QML QtCharts 极坐标图(PolarChartView)
极坐标图(PolarChartView)
极坐标图使用极坐标系而不是笛卡尔坐标系来显示数据，适用于周期性数据的可视化。
PolarChartView常用属性
| 属性 | 类型 | 描述 |
|---|---|---|
| angularAxis | AbstractAxis | 角度轴(通常为CategoryAxis) |
| radialAxis | AbstractAxis | 径向轴(通常为ValueAxis) |
| theme | enumeration | 图表主题 |
| animationOptions | enumeration | 动画选项 |
| antialiasing | bool | 是否启用抗锯齿 |
极坐标图支持的系列类型
- LineSeries
- SplineSeries
- AreaSeries
- ScatterSeries
