Detailed Description

An item to render a pie chart.

This item will render a Pie chart based on the valueSources supplied to it. By default it will set indexingMode to IndexSourceValues, meaning that it will use the individual values of the valueSources to render sections of the chart.

Usage example

import QtQuick
import QtQuick.Controls
import org.kde.quickcharts as Charts
Charts.PieChart {
width: 400
height: 300
valueSources: Charts.ModelSource {
roleName: "data";
model: ListModel {
id: listModel
ListElement { data: 12 }
ListElement { data: 19 }
ListElement { data: 10 }
ListElement { data: 13 }
ListElement { data: 13 }
colorSource: Charts.ArraySource { array: ["red", "green", "blue", "yellow", "cyan"] }
nameSource: Charts.ArraySource { array: ["Red", "Green", "Blue", "Yellow", "Cyan"] }
thickness: 50
The resulting pie chart.

Multiple Value Sources

Multiple valueSources are rendered as consecutive pie charts in the same item. The first valueSource will become the outermost circle and consecutive valueSources will be rendered as continuously smaller circles. When rendering multiple value sources, filled will only affect the last value source. All other value sources will be rendered according to thickness, with spacing amount of space between them.

Property Documentation

◆ backgroundColor

QColor PieChart::backgroundColor

Sets a colour to use to fill remaining space on the pie.

The default is transparent.

Definition at line 99 of file PieChart.h.

◆ filled

bool PieChart::filled

Whether to use a filled pie or not.

If true, the last pie rendered will be rendered as a filled circle. The default is false.

Definition at line 72 of file PieChart.h.

◆ fromAngle

qreal PieChart::fromAngle

The starting angle of the arc used for the entire pie.

When set, instead of rendering a full circle, the pie will be rendered as an arc. The default is 0.

Definition at line 109 of file PieChart.h.

◆ range

RangeGroup * PieChart::range

The range of values to display in this PieChart.

When set to "automatic", the values will be divided across the entire chart.

Definition at line 64 of file PieChart.h.

◆ smoothEnds

bool PieChart::smoothEnds

Smooth the ends of pie sections.

When true, this will try to smooth the ends of sections. This works best when filled is false. The default is false.

Definition at line 130 of file PieChart.h.

◆ spacing

qreal PieChart::spacing

The amount of spacing between pies when rendering multiple value sources.

The default is 0.

Definition at line 90 of file PieChart.h.

◆ thickness

qreal PieChart::thickness

The thickness of an individual pie, in pixels.

If filled is set, this is ignored for the last pie. The default is 10px.

Definition at line 81 of file PieChart.h.

◆ toAngle

qreal PieChart::toAngle

The end angle of the arc used for the entire pie.

When set, instead of rendering a full circle, the pie will be rendered as an arc. The default is 360.

Definition at line 118 of file PieChart.h.
