Name

Description

CreateChartValues

Creates the FMX.RS.ChartPanel.TRSChartValues class for the Values property

Notes to Inheritors
Override this method to create your TRSChartValues descendant

CreatePreviewValues

Creates sample values for illustrating how the chart will look. This function is automatically called at design-time to fill the chart with sample values. It can also be called at run-time to add more values to the chart (i.e., the chart is not cleared first)

Note
Set the Preview property to false to have the design-time sample values show up at run-time

DrawSlices(TCanvas,TCanvasRect,TPieSliceOptions)

Draw all the pie slices of the chart (Overrides FMX.RS.Charts.TRSPieChart.DrawSlices(TCanvas,TCanvasRect,TPieSliceOptions).)

GetChartType

Returns the chart type enumerated value for this class. Each chart class overrides this class function to return the RSChartConsts|TRSChartType enumerated value (Overrides FMX.RS.DonutCharts.TRSDonutChart.GetChartType.)

GetRadius(TRSPieChartValue,Single,Single)

Returns the InnerRadius and OuterRadius of the pie chart (Overrides FMX.RS.Charts.TRSPieChart.GetRadius(TRSPieChartValue,Single,Single).)
