Labels Page - Pie Charts and Doughnut Plots
Data point labels can be shown on most plot types in Grapher. For pie charts and doughnut plots, the labels can show the information in the labels column, data values, or the percentage the data value is of the whole pie. Labels can also be customized to appear in specific locations and can use a variety of formats, fonts, and colors to optimize the look and feel of the graph.
Pie charts and doughnut plots are automatically labeled with two labels. The top label is the text in the worksheet's label column. The second label is the percentage of the pie for that slice. Either label can be altered to display data value, as well.
The following information is for the options contained on the pie chart and doughnut plots Labels tabs. To edit the labels, click on a pie chart or doughnut plot to select it. In the Property Manager, click on the Labels tab.
