Creating a chart in gnumeric is a simple process. After entering the data, select the range of data that you want to be represented in the chart.

Go to Insert > Charts, and a chart wizard should appear. The Chart wizard in Gnumeric is known as the Chart Guru. There are sixteen kinds of charts available by default - others are available using plug-ins. Select on of the chart types, and select the variables in the wizard. Once you are done configuring the Chart Guru, the chart does not immediately appear on the sheet. You have to manually click and drag the chart across the sheet, which is a welcome deviation from the norm in spreadsheet applications. This allows you to position and set the size of the chart without having to manipulate it later on. The chart is linked to the selected contents, so every time you change the data in the cells you selected to make the chart, these changes are reflected in the chart in real time.
