Pie charts (the following figure) are most often used to display a few components that are easily distinguishable. Typically, each slice of a pie chart displays statistics from one variable. For example, a pie chart can display one employee's High, Medium, and Low tickets. When you display a pie chart flashboard, the individual percentages of each slice are displayed. You can display both percentages and actual values of each slice by setting the showvalues parameter to 1. (See Customizable parameters.)
Pie charts are not recommended to display:
- Subtle or slight changes in the segments.
- Many components at once.
- Relative size of components.
- Variables using a double Group By option.
You cannot use a pie chart flashboard to display historical data or summary data. If you try to use a pie chart to display this type of data, an error is displayed.
