Creating a Graph using OpenOffice
Sometimes, it is more useful to display data graphically: for this reason, the OpenOffice spreadsheet module allows you to transform numeric data into graphs or charts. In this section, we will use the spreadsheet updated in the previous section on spreadsheet formatting as an example. Open the file using:
File->Open
Select the data that you want to graph - including the headings:

Now select the following:
Insert->Chart

A wizard will open up, displaying the available chart/graph types:

Click "Finish" to select the default chart type (a bar chart):

This looks good, but the legend is superfluous, so let's remove it by clicking over the whitespace on the graph image and select "Delete Legend":

Now, grab the bottom right corner and drag it out until you can read all the values on the x axis:

To add a title, click over the graph area and choose "Insert Titles..":

Type in the required title text and click "OK":

Right click one of the bars in the chart and select "Insert Data Labels":

The bar chart should now look as follows:

However, we now decide that this data is better represented by a pie chart: simply right click over the chart and choose "Chart Type..":

Select the exploded pie chart and click "OK":

But now we need the legend (key), so right click the white space around the pie chart and select "Insert Legend":

Finally, it would be nice to have the pie values shown in percentages, so double-click over the graph area, then right click one of the pie segments and choose "Format Data Labels.." option:

Select the "Show value as percentage" options and deselect the "Show value as number" option before clicking "OK":

The pie chart should now look as follows:

Finally, Save the file using CTRL+S or File → Save:

Once saved the application can be exited, using File → Exit or CTRL+Q:
