Configuration options

Common configuration options are inherited for pie charts, but there are also some options that are specific to pie and doughnut charts. These are listed in the following table:

Property	Value	Description
cutoutPercentage	Number. Defaults: 0 for 'pie', and '50' for doughnut	A percentage of the chart that is cut out from the middle
rotation	Number. Default: -0.5 * Math.PI	The starting angle to draw the arcs
circumference	Number. Default: 2 * Math.PI	The circumference of the pie

Configuration options for pie and doughnut charts

These options are merged (and override) global configuration options. Default options for each type of chart can also be set through the Chart.defaults.doughnut and Chart.defaults.pie objects, which support the same properties listed earlier.
