The TRSChartPointInfo class publishes the properties of the TRSCustomPointInfo class. It encapsulates the points metadata for a FMX.RS.Charts.TRSPointChart (or FMX.RS.Charts.TRSCustomPointChart) component. The TRSCustomPointChart component uses this class for its PointsInfo property, which specifies the appearance of all points in a point chart.

Namespace: FMX.RS.Charts

Name

Description

published property

Brush

Represents property Brush.

published property

DefaultStyle

Represents property DefaultStyle.

published property

Height

Represents property Height.

public property

OnChange

Occurs immediately after the chart graphic object changes. Write an OnChange event handler to take specific action when the chart graphic changes. The properties of the chart graphic reflect the new settings when OnChange occurs.

alert_cautionWarning

For chart graphics that a chart or chart panel creates, you shouldn't assign a handler to this event. The chart or chart panel has already assigned an event handler.

public property

Opacity

Specifies the opacity of the graphic when drawn. The opacity is a value between 0 (invisible) and 1 (fully opaque). Any value in-between controls the transparency of the value.

alert_cautionImportant Note

This is an FMX only feature. Any value > 0 is drawn fully opaque in the VCL version

public property

Owner

Represents property Owner. (Inherited from FMX.RS.Charts.TRSCustomChartPointInfo.)

published property

Pen

Represents property Pen.

published property

Style

Represents property Style.

public property

Visible

Indicates whether this graphic should be drawn or not. The chart panel uses the Visible property to determine if it should call the Draw method for the chart graphic.
 (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)

Width

Represents property Width.

expandingMethods

 

Name

Description

public method

Assign(TPersistent)

Copies the contents of another similar object to the current object

alert_noteNotes to Inheritors

Most objects override Assign to handle the assignment of properties from similar objects. When overriding Assign, call the inherited method if the destination object cannot handle the assignment of properties from the class of the Source parameter

protected method

Changed

Overloaded. Represents method Changed. (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)

public method

Clone

Creates a "deep" copy of the chart graphic. It constructs a new chart graphic of the correct type and then calls the   Assign method to copy its properties to the new copy. (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)

public method

Draw(TCanvas,TCanvasRect)

Overloaded. Paints the chart graphic to the specified Canvas in the specified location. It uses the current canvas' brush and pen. Use the Draw method to paint the chart graphic to any canvas and anywhere and with any size on the canvas.

alert_noteNotes to Inheritors

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

public method

Draw(TCanvas,TCanvasRect,TRSChartAxis,TRSChartAxis)

Overloaded.  Paints the chart graphic to the specified Canvas in the specified location. It uses the current canvas' brush and pen. Use the Draw method to paint the chart graphic to any canvas and anywhere and with any size on the canvas.

The VertAxis and HorizAxis parameters can be used to provide point to pixel conversions (see FMX.RS.ChartPanel.TRSChartAxis ).

alert_noteNotes to Inheritors

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

protected method

Drawing(TCanvas,TCanvasRect)

Represents method Drawing(TCanvas,TCanvasRect). (Overrides FMX.RS.ChartPanel.TRSChartGraphic.Drawing(TCanvas,TCanvasRect).)

protected method

Drawn(TCanvas,TCanvasRect)

Represents method Drawn(TCanvas,TCanvasRect). (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)

protected method

DrawPoint(TCanvas,TCanvasRect,Single)

Represents method DrawPoint(TCanvas,TCanvasRect,Single). (Inherited from FMX.RS.Charts.TRSCustomChartPointInfo.)

protected method

FreeNotification(TObject)

Represents method FreeNotification(TObject). (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)

protected method

Initialize

Represents method Initialize. (Overrides FMX.RS.ChartPanel.TRSChartGraphicArea.Initialize.)

protected method

InitializeEvents

Represents method InitializeEvents. (Overrides FMX.RS.ChartPanel.TRSChartGraphic.InitializeEvents.)

protected method

InternalDraw(TCanvas,TCanvasRect)

Represents method InternalDraw(TCanvas,TCanvasRect). (Overrides FMX.RS.ChartPanel.TRSChartGraphicArea.InternalDraw(TCanvas,TCanvasRect).)

protected method

SenderChanged(TObject)

Overloaded. Represents method SenderChanged(TObject). (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)

public method

TiledDraw(TCanvas,TCanvasRect,TTileGraphic,TCanvasPixel,TCanvasPixel)

Overloaded.  Tiles the image across the entire input rectangle.

The Image is drawn at full size from the top left of the ARect across and down until outside of the input rectangle. Use the overloaded TiledDraw methods to constrain the size of the Image.

public method

TiledDraw(TCanvas,TCanvasRect,TTileGraphic,TCanvasPixel,TCanvasPixel,TCanvasPixel,TCanvasPixel)

Overloaded.  Tiles the image across the entire input rectangle.

The Image is drawn at ImageWidth, ImageHeight size from the top left of the ARect across and down until outside of the input rectangle.

public method

TiledDraw(TCanvas,TCanvasRect,TTileGraphic,TCanvasRect)

Overloaded.  Tiles the image across the entire input rectangle.

The Image is drawn at ImageRect size from the top left of the ARect across and down until outside of the input rectangle.

protected method

VisibleChanged

Represents method VisibleChanged. (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)

expandingEvents

 

Name

Description

public event

OnDraw

Occurs just after the chart graphic is painted. Write an OnDraw event handler to take specific action when the chart graphic has finished painting. The OnDraw event also allows you to do custom painting after the chart graphic has painted. (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)

public event

OnDrawing

Occurs just before the chart graphic is painted. Write an OnDrawing event handler to take specific action when the chart graphic is about to paint. If the event handler sets the DoDraw parameter to False, the chart graphic will not be painted. The OnDraw event also allows you to do custom painting before the chart graphic has been painted. (Inherited from FMX.RS.ChartPanel.TRSChartGraphic.)
