I take every opportunity to manage my data sharing. I normally do not share my data when given the choice, but I'm not proactive. I only share my data with companies I trust. I use a VPN, private browsing or other tech tools to improve privacy.
Managing my data effectively is too much trouble, so I don't bother. Privacy in the digital age is impossible. Trying to protect it is a waste of time. Technically, these are contiguous sequences of digits which may have a separator symbol between the thousands and another symbol indicating the decimal separator.
These symbols follow the English convention by default comma as thousand separator, period as decimal symbol but will adopt the symbols appropriate for a different locality if Gnumeric is launched in a particular way see Section For instance, in a French setting the period is the thousand separator symbol and the comma the decimal separator symbol. By default, Gnumeric displays numeric values lined up against the right side of the cell. Several other types of input are recognized as numeric values which means that calculations can be performed on the values in the cells.
For more information on numbers, see Section 5. If Gnumeric cannot understand the formula which is entered, it will open a dialog box which may have an explanation and gives you a chance either to re-edit the expression or to accept the entry as a text entry instead of a formula.
The second choice makes it easy to re-edit the entry into a valid formula simply by fixing the formula and removing the leading apostrophe ' before the equals sign. Formulas can be quite complex since the power of spreadsheets comes from these formulas. A simple example of the use of a formula is as follows: first, select cell B2 and input the value "3" into that cell. Cell D4 should display the value "5". If the value of cell B2 is changed from "3" to "", Gnumeric will automatically update the value of cell D4 to "".
Formulas may include calls to functions. These are statements which indicate that more complex operations should be performed. The cell would then display "2. Certain functions return not just a single value but an array of values.
For more details see Section 5. As was shown in the example above, formulas may contain references to the contents of another cell. In the example given above, the contents of the cell in the second column and the second row was used in a calculation by using the cell name "B2".
These references mean that complex calculations can be automatically updated when one of the original values change. You can make references to the cells in other worksheets and even to those in other workbooks files. The basic format of a complete reference is made of the name of the file the reference is in, enclosed by square brackets, followed by the name of the sheet, followed by an exclamation point, followed by the letter s of the column name, followed by the number of the row.
These complete references can be shortened if the filename or sheet names are the same as that of the reference. References can identify a contiguous range of cells. For instance, the reference "A1:E5" refers to all the cells from the top left corner of the current sheet to the cell five rows down and five rows over.
This can be useful in a formula which uses a function such as MAX. For more information on references see the complete discussion in Section 5. For more on the use of formulas see Section 5. Error values are almost never entered into the spreadsheet directly but generally arise when formulas cannot calculate valid results.
The data in Gnumeric are stored in the cells of the spreadsheet, each of which has a cell format which dictates how the data will be displayed, whether the cell will have borders and other information. Cell formatting can be quite confusing at first because it combines simple changes, such as the colour of the characters being displayed, with more complex ideas, such as how future changes to the cell will be interpreted.
All of the cell formatting commands can be reached through a context menu by right clicking on a cell and selecting the Format Cells This will open a dialog window with tabs which group together similar types of formatting. Clicking on the Font tab allows you to change the font family, style, size and colour. For instance, if the cell B2 contained the text "Hello, this is my first spreadsheet" then you can make this text bigger by selecting a larger font size.
Simple changes to the format of a cell include changing the alignment of the characters, changing the font type or colour, changing the border, and changing the colour or pattern of the background. The Alignment , Font , Border , and Background tabs are simple to understand simply by playing around with the settings and looking at the effect on a cell which contains text. The Protection and Validation tabs are advanced functionality which you can ignore at the beginning.
For explanations of these tabs, see the advanced description in Section 5. Cell formats are most difficult to understand when they address the type of data stored and the visual display of that data. This only arises with the options selected in the Number tab of the Format Cells dialog. While these ideas are complex, you need to understand them early on as they are fundamental to spreadsheet use. When you enter data into Gnumeric , the spreadsheet interprets the entry based on the input format of the cell.
The default format of empty cells is the General format which instructs Gnumeric to guess both the type of the data being entered and a suitable display format for that data type.
However, you can change the General format to a specific format in order to alter both the way Gnumeric interprets any future data input to the cell and the way data in the cell are displayed. Changing the format does not alter the data type of data already in a cell but does alter the display format of that data.
This means that the input format will only affect future input whereas the display format will affect both the data currently in the cell and any data placed later into the cell. Usually, the value Gnumeric uses for dates is the number of days since January 1st, The order in which the formatting operations occur is critical. It is not possible to alter the type of a datum currently in a cell by formatting. To alter the interpretation of the data type in a cell, formatting must occur prior to the entry of the data.
It sometimes becomes necessary to override the "General" type if Gnumeric is making an incorrect assessment of the data being entered. Postal Zip Codes in the United States, for instance, are incorrectly interpreted to be numbers. Some of these Zip Codes start with a leading zero which the "General" format type drops so the user must intervene to keep that zero displayed.
In order to input these Zip Codes, the following steps must be performed. First, the cell must be selected. Next, the cell must be formatted to hold a "Text" value. This formatting changes both the interpretation of any future data entry into this cell and alters the display formatting of the cell. Finally, the Zip Code can be entered. Following these steps, the data value will be considered to be a "Text" value, any leading zeros will be retained and the data will be left justified since this is the default display format for "Text" values.
If you need to alter the data type of a whole column prior to data entry, you can do this in one formatting operation.
You can click the right mouse button on the column header the letters at the top and select Format 1 Column from the context menu, or you can first select the whole column by clicking on the column header, then selecting the Format menu and the Cells This quick approach to pre-formatting cells can be done for any group of selected cells. Selections can be more complex than a single cell at a time. Selections may describe a continuous rectangular block of cells, an arbitrary shaped group of cells or even a discontinuous group of cells.
The most common way to select a continuous rectangular block of cells uses a click and drag mouse motion. You can select the cells in this continuous block by clicking and holding the left mouse button down on one of the corner cells for instance, the top, leftmost cell and dragging the mouse cursor to the opposite corner for instance, the bottom, rightmost cell before releasing.
The selection box will expand to include all of the cells in this range. The most common way to select an arbitrary shaped or discontinuous group of cells is to hold down the Ctrl key while using the mouse to select cells. If the cell containing the mouse cursor when you click is not part of the selection, it is added, as are any other cells enclosed in the selection box when the mouse button is released. If the cell initially containing the mouse cursor is already selected, the click or click-and-drag action instead removes all the enclosed cells from the selection.
As long as you hold the Ctrl key down, all of the cells included by a click or a click and drag motion will be added to or removed from the selection. For example, to perform an operation on all the cells in a square area except those on its diagonal, begin by clicking and dragging to select the square area.
Next press and hold the Ctrl key and click on each of the cells on the diagonal, removing them from the selection. There are several operations which cannot be performed with odd shaped or discontinuous groups of cells. For more information and other ways to select multiple cells, see the complete discussion in Section 5. The contents of cells, both data values and formatting, can be moved from one part of a spreadsheet to another so that data do not have to be re-entered if the spreadsheet is reorganized.
New cells can be added to a spreadsheet and old cells removed but these latter operations cause the layout of the spreadsheet to be altered. The simplest way to move cell contents around a spreadsheet involves selecting a block of cells containing the contents to be moved, either "cutting" or "copying" those cells, selecting the location where these contents are to be moved and then pasting the data.
Moving data can only be performed with a single selection of cells which means that only continuous rectangular blocks of cells can be moved. This does mean, however, that columns or rows can be moved as a unit. By default, Gnumeric moves the entire contents of the cells including both the data values and the formatting of the cells.
If cells are "cut" the contents will be removed from the current location. If cells are "copied", the contents will be duplicated in the new location. These two operations treat cell references in formulas slightly differently.
If cells are "cut", any references in the cells in the new location will remain pointed at the original cells. If cells are "copied", the references in the cells in the new location will point to cells in the same relative position.
You can select the new location for the cells in two ways. The simplest is to select the top, left cell of the new location. Alternatively, you can select the whole new range of cells but the shape of this new range must match exactly the dimensions of the original range which is more difficult. An alternative way to move cells in a current worksheet involves dragging and dropping the original selection.
You select the cells to be moved as above. You then place the mouse cursor on the thick white selection border.
If you click and hold the left hand button, you can drag the selected cells to a new location resulting in the same operation as a "cut" and a "paste". If you hold down the Ctrl key during the click and drag of the mouse, the result is the same as a "copy" and "paste" operation and can be repeated several times.
Both the Edit menu and the context menu have an extra menu entry called Paste Special This option allows the transfer of only the cell contents, only the cell formats or only the calculated values of the cells. The transferred contents can also be mathematically combined with the current contents of cells in the new location.
Alternatively, the selection can be transposed. See Section 5. A worksheet can also be altered by inserting or by deleting cells. These operations actually alter the locations of cells in a workbook. Inserting and deleting columns and rows are easy to understand. If you select a group of columns or rows, selecting the Column or Row menu entries in the Insert menu will add the same number of columns to the left of the selected columns or of rows above the selected rows.
You can also use the context menu for the insert operation. The context menu can be used to delete the currently selected columns or rows.
Insert operations can result in the loss of data if the last columns or rows currently contain information. Individual cells or contiguous rectangular blocks of cells can also be inserted and deleted. During this operation, you are asked which way to shift the current cells to allow the insertion or deletion of the selected cells.
The movement can be along the rows or along the columns and will result in the relative movement of cells which were previously contiguous.
This shift is the fundamental difference between insert and delete operations compared to cut or copy and paste operations. The worksheets in a workbook can be altered in several ways. The name of a particular worksheet can be altered.
New sheets can be added. A current sheet can be duplicated or removed. The sheets can be reordered. Other sheets operations can alter the colour of the tabs or change the "protection" status of a worksheet to allow cells to be locked or hidden. To change the name of a worksheet, right-click on its tab to access the Worksheets context menu and select Rename.
Edit the New Name field and click on OK to set the new worksheet name. You can insert a new empty sheet after the current sheet through the Sheet menu entry in the Insert menu or through the context menu which appears when you click the right mouse button on a tab. Instead of an empty sheet, you can add a copy of the current worksheet to the workbook after the current sheet by selecting the Duplicate menu entry from the context menu. You can remove the current sheet using the Remove menu entry from the context menu.
You can re-order worksheets from the Manage Sheets dialog. Many of these operations can be performed at once from the Manage Sheets dialog which can be opened through the Manage Sheets A major function of moderns spreadsheets is to provide a quick and easy way to plot numerical data in graphical charts of various kinds. The use of graphs provides users a way to explore data to discover relationships and trends in the data values.
Graphs also provide an effective way to present data so as to demonstrate relationships in the data and summarize large amounts of data in an effective image. In Gnumeric , both of these can be done easily and efficiently.
When graphs are used to explore data, the aim is usually to produce a plot quickly with a minimum of effort. These plots are not designed to look polished but must present the required information as quickly as possible. To produce these graphs, users must learn a simple series of operations which will produce the desired plots.
For speed, the most critical operation involves selecting the cells on the spreadsheet which will be used as data before starting the graphing process. Graphs which are used to present data must be carefully crafted to communicate effectively.
Clarity of communication is the critical factor and the plot may include a large amount of work to ensure that the visual result of the plot helps to communicate the desired result. The use of a graph may not be the best way to communicate information. A verbal explanation or a simple table are often sufficient and, because they are more compact, may be more effective ways to communicate.
Graphs which use a large number of the graphical features available in Gnumeric often appear cluttered. The visual richness of such images can often obscure the message contained in the presentation of the data.
Sparse, elegant and direct graphs will communicate results most effectively. This section will introduce the process of creating a graph by presenting an example of a side-by-side column plot. Because a graph requires data, it is first necessary to create some simple data to use in these examples. First we have to input these data into a worksheet. The data used are shown in Figure For clarity in this discussion, the word "Interval" should be in cell A1.
A column plot presents a series of data points as columns whose height depends on the value of each datum. This is a useful type of plot to show the number of eggs produced in each interval.
The quickest way to make a plot starts with the selection of the data. Using the mouse, first select the range A1:C5 which includes the data both for the number of Eggs and for the number of Females.
Next, click on the graphing toolbar button which looks like three colored pillars. This launches a new window called the graph guru. Next, click on the word "Column" next to the icon with vertical colored bars which will move the selection to that row. Click on the "Insert" button. This will make the druid disappear and leave the mouse cursor as a thin cross hair. Finally, we will place and size the graph on a sheet. Click on the sheet and drag downward and to the right.
As the mouse is dragged, a rectangle will expand. When the mouse button is released, a simple column chart should appear. The simple graph should look like Figure The graph can be customized with titles, extra charts, overlaid plots, label boxes and lots of extra information. To customize the graph, right click on the plot to open the graph custom menu. The graph context menu will appear as shown in Figure This menu provides access to several functions.
Users can customize the appearance of graphs by selecting the Properties menu item, can save the graph into PNG or SVG formats using the Save as image menu item, can reorder the various graphical elements displayed in the worksheet using the Top , Up , Down , and Bottom menu items or can delete graphical elements with the Delete menu item. If we wanted to add a title and a legend to the graph, we could use the Properties menu item to open the graph editor and customize the graph as follows:.
Right click on the graph to open the context menu and select the Properties menu item. This will open the graph editor. The graph editor opens with the top-level "Graph" entry selected in the element tree displayed in the top left pane of the editor. The top right pane of the editor displays a preview of the eventual graph. The bottom pane of the editor has a single or several tabs presenting the elements which can be modified for the particular item selected in the element tree.
Click and hold on the Add button to open the menu of elements addable to a graph. Note that this menu changes depending on the element selected in the element tree when the Add is clicked. Drag the mouse cursor down until the selection highlights the "Title" entry and release the mouse button. This will add a "Title" node in the graph element tree and change the selection to this "Title" node. The bottom pane of the graph editor will also change to display the modifiable characteristics of the "Title" element.
In the text field of the tab displayed in the bottom pane of the graph editor, add a title such as "Egg Production and Female Productivity" and type the Enter key. Note that the title appears at the top of the graph in the preview pane. In the graph tree, select the node labelled "Chart1". Next, click and hold on the add button, drag down to the Legend menu item and release. Note that this adds a legend on the right of the graph in the preview pane.
Click on the "Apply" button. The plot should now have a title and a legend. Note that Gnumeric has used the words in the column headers automatically to label the two data series in the legend. The modified graph should look like Figure Printing can be done using the toolbar buttons or can be accessed through the File menu.
Printing usually involves configuring the page properties like the paper type and margins , then previewing the document to be printed and finally actually printing the document. In order to configure a worksheet for printing several parameters must be set such as the correct size of the paper sheet, the layout of the spreadsheet, headers and footers and such information.
These parameters can be set once for all of the worksheets in a file or separately for each worksheet. The Page Setup The Print Preview By default, printing only applies to the current worksheet but this can be changed in the print dialog explained next. The Print Various printers can be selected and the parameters of the job, such as whether to print all the worksheets or only the currently selected worksheet, can be altered.
Clicking on the Print button will perform the printing task. When you first start Gnumeric a new workbook will be opened. This brings up the file dialog where you can pick the filename and format for the book you are saving.
It is best to save the book in the Gnumeric XML file format the first time. This allows you to easily edit the file without worrying about changes in the format and look of the book. Once the file has a name and a file format, saving subsequent changes can be done easily either through the File menu, through the toolbar or through a keyboard shortcut. Saving with the menu requires selecting the File and then the Save menu item.
Saving with the toolbar simply requires clicking on in the tool bar. Sometimes you want your book to be saved often so you do not lose any work. The Auto Save dialog appears. When the interval is shorter more of your work will be potentially saved, but Gnumeric might appear sluggish. If Gnumeric is sluggish increase the time between saves. The button Prompt Before Saving brings up a dialog to ask if you want to save the book. Using the automatic saving feature of Gnumeric can save time but is dangerous.
Gnumeric does not create a new file each time a file is saved but instead Gnumeric modifies the existing file which destroys the previous work.
In certain situations, this feature can lead to the loss of possibly important work. Users are highly recommended to backup their work by copying the original file to a new name or by saving files to newly named files. An existing spreadsheet file can be opened in several ways. If the file has an icon on the desktop, this icon can be clicked or double-clicked with the mouse button.
Similarly, if a file manager, such as the Nautilus file manager, lists the file, then the file name can be clicked and opened. If Gnumeric is already opened, a file can be opened by clicking on the File and selecting the Open menu item. Alternatively, the "Open file" button on the toolbar, , can be used or the F3 key clicked.
All three of these open the Open File dialog. You can then select the spreadsheet file you wish to open. Gnumeric can open many different types of spreadsheet file formats. If the file has recently been opened in Gnumeric , the file name will appear in the File menu and can simply be clicked to re-open the file.
There are several ways to close Gnumeric. The simplest is to select the File menu and then the Quit menu option at the bottom of the File. Gnumeric can also be closed through the window manager by clicking on a close box in the window frame or through a pop-up menu. The placement of the box and the invocation of the menu depend on the particular window manager and the theme being used. If the GNOME panel is running the window list applet, clicking with the right mouse button opens a context menu with a Close which can be used to close Gnumeric.
If any changes have been made to the workbook since the last time it was saved, a dialog will open to ask what is supposed to happen to the contents of the workbook. At this point the contents of the workbook can be saved Save , the request to close gnumeric can be cancelled Don't Quit or the most recent changes can be discarded Discard.
If the user decides to save the content, a second dialog may open requesting a file name, location and type for the saved workbook. To delete files that were created by Gnumeric any graphical file manager such as the GNOME file manager Nautilus or the shell command rm can be used. This part of the Gnumeric manual explains the pieces of the software that users can manipulate. The menus, the toolbars and the cell grid area comprise what is called the graphical user interface of an application because it is an interface a way to interact with Gnumeric which is made of graphical elements pictures designed to be used by human users.
Gnumeric opens by default with a view of an empty workbook which is called "Book 1" and which contains three worksheets: "Sheet1", "Sheet2", and "Sheet3" as can be seen in Figure The outermost portion of the window is not actually part of Gnumeric and may look different on different machines. Gnumeric attempts to place its name and the name of the workbook on this outer portion. The majority of spreadsheet work is done while interacting with this view of Gnumeric.
All of the functions which Gnumeric provides can be accessed quickly from here. The graphic elements of Gnumeric are made of several independent pieces. Figure shows a newly opened, empty Gnumeric with the principle elements labelled. The elements names are listed below along with a reference to the section that discusses that element. Those reading this document on their computers may be able to click on the references to jump to that section of the manual.
Almost everything that can be done in Gnumeric can be done through the menus. The menus and menubar are discussed in Section 4. The toolbars are discussed in Section 4. It is presented in Section 4. This toolbar enables the user to draw graphic elements on the sheet, such as text labels, big red circles or thin green arrows.
These can be used to bring attention to a particular part of a worksheet. The object toolbar is explained in Section 4. It is discussed in Section 4. The use of these elements is explained in Section 4. This area is used by Gnumeric to give feedback on the status of certain operations. This information is explained in Section 4.
