ZoomCharts Documentation

This setting determines how much of the available visual container area is used to draw the pie chart. The default value is 60%, but you can use a custom percent value between 20 and 100.

Smaller pie chart radius values will reduce the pie chart’s radius and create more blank space, while higher values will create a larger pie chart within the available container.

Keep in mind that a large pie chart radius value may not leave enough space for Detail Labels (with Outside as Label Placement) or Legends to be displayed properly.
