10 Pie chart
| Toolbar icon: | ![]() |
A pie chart is actually a special case of a 100% chart with only one category (column) of data.
Each segment of a pie chart shows three handles, when selected. Each of the handles can be dragged with the mouse to rotate the pie. When rotating, the handles snap at positions 0∘, 90∘, 180∘ and 270∘, making it easy to create an aesthetically pleasing layout.
The pie chart remembers which handle you were dragging when rotating the chart and preserves the correct orientation even when the data is changed. In addition, you can drag the handles away from the pie in order to explode the respective pie segment.
The labels of the pie chart support the label content property, which lets you choose if you want to display absolute values, percentages, or both (‘Label content’). Additionally you can move each outside label to place it anywhere on the outer edge of the respective segment.
Universal connectors can be used to connect pie charts with other chart types (see ‘Universal connectors’).
