TRSGuideChart Methods

Name

Description

CreateBrush

Represents method CreateBrush. (Overrides FMX.RS.ChartPanel.TRSCustomChart.CreateBrush.)

CreateChartValues

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

Notes to Inheritors
Override this method to create your TRSChartValues descendant

CreatePen

Represents method CreatePen. (Overrides FMX.RS.ChartPanel.TRSCustomChart.CreatePen.)

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

DoUpdateAxisInfo(TRSChartAxis)

Represents method DoUpdateAxisInfo(TRSChartAxis). (Overrides FMX.RS.ChartPanel.TRSCustomChart.DoUpdateAxisInfo(TRSChartAxis).)

DrawGuide(TCanvas,TCanvasRect,TCanvasPixel,TCanvasPixel,TLineOrientation,Single)

Draws one guide

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.ChartPanel.TRSCustomChart.GetChartType.)

InitializeChart

Creates and initialize structures and values of chart. This method is the safe place to initialize chart values without change events occurring.

Notes to Inheritors
The constructor calls this method. Use this method to actually create and initialize properties. Do not assign event properties in this method (use the InitializeChangeEvents method instead)

InternalDraw(TCanvas,TCanvasRect)

Overloaded. Paints the chart graphic to the specified canvas at the specified rectangle. The InternalDraw method is called by the Draw method.

Descendant classes of TRSCustomChart override the InternalDraw method to actually paint themselves.

Notes to Inheritors
The default InternalDraw method implementation assigns the Brush, Pen , and Font to the Canvas.

MouseHover(TCanvasRect)

Represents method MouseHover(TCanvasRect). (Overrides FMX.RS.ChartPanel.TRSCustomChart.MouseHover(TCanvasRect).)
