API reference

| Method | Description | Default | | --- | --- | :--: | | data(array) | Getter/setter for the pie chart data, as an array of series objects, each representing a pie slice. | [] | | width(number) | Getter/setter for the chart width in px. | <window width> | | height(number) | Getter/setter for the chart height in px. | <window height> | | label(string or fn) | Getter/setter for a series object label accessor, used to display labels on the slices and their tooltips. | name | | size(string or fn) | Getter/setter for a series object size accessor, used to compute the angular length of the slices. | value | | color(string or fn) | Getter/setter for a series object color accessor, used to color the slices. | () => 'grey' | | sort(fn) | Getter/setter for the compare method used to sort the series. A value of null (default) maintains the existing order found in the input data structure. This method receives two arguments representing two series objects and expects a numeric return value (-1, 0 or 1) indicating the order. For example, to order slices by size, use: (a, b) => b.size - a.size. | <existing order> | | showLabels(boolean) | Getter/setter for whether to show labels in the slices. Regardless of this setting, labels too large to fit within a slice's boundaries are automatically hidden. | true | | tooltipContent(fn) | Getter/setter for a series object tooltip content accessor function. Use this to specify extra content in each of the slice's tooltips in addition to the series name that's included by default. | <value (%)> | | onClick(fn) | Callback function for click events. Includes the series object as single argument. | | | onHover(fn) | Callback function for mouse hover events. Includes the series object (or null if hovering outside the pie area) as single argument. | |
