PieChart

fun PieChart(values: List<Float>, labelPositionProvider: LabelPositionProvider, modifier: Modifier = Modifier, slice: @Composable PieSliceScope.(Int) -> Unit = { val colors = remember(values.size) { generateHueColorPalette(values.size) } DefaultSlice(colors[it]) }, label: @Composable (Int) -> Unit = {}, labelConnector: @Composable LabelConnectorScope.(Int) -> Unit = { StraightLineConnector() }, holeSize: Float = 0.0f, holeContent: @Composable () -> Unit = {}, minPieDiameter: Dp = 100.dp, maxPieDiameter: Dp = 300.dp, forceCenteredPie: Boolean = false, animationSpec: AnimationSpec<Float> = KoalaPlotTheme.animationSpec)

Creates a Pie Chart or, optionally, a Donut Chart if holeSize is nonZero, with optional hole content to place at the center of the donut hole. Pie slices are drawn starting at -90 degrees (top center), progressing clockwise around the pie. Each slice occupies a fraction of the overall pie according to its data value relative to the sum of all values.

Parameters

values

The data values for each pie slice

labelPositionProvider

A provider of label offsets that can be used to implement different label placement strategies. See the PieChart override for a version that uses labels placed around the circumference of the pie.

modifier

Compose Modifiers to be applied to the overall PieChart

slice

Composable for a pie slice.

label

Composable for a pie slice label placed around the perimeter of the pie

labelConnector

Composable for label connectors connecting the pie slice to the label

holeSize

A relative size for an inner hole of the pie, creating a donut chart, with a value between 0 and 1.

holeContent

Optional content that may be placed in the space of the donut hole.

minPieDiameter

Minimum diameter allowed for the pie.

maxPieDiameter

Maximum diameter allowed for the pie. May be Infinity but not Unspecified.

forceCenteredPie

If true, will force the pie to be centered within its parent, by adjusting (decreasing) the pie size to accommodate label sizes and positions. If false, will maximize the pie diameter.

animationSpec

Specifies the animation to use when the pie chart is first drawn.
