TRSChartLayer Class

Create

Initializes a new instance of the TRSChartGraphic class. (Inherited from RSChartPanel.TRSChartGraphic.)

Destroy

Represents the destructor of the TRSChartLayer class. (Overrides RSChartPanel.TRSChartGraphic.Destroy.)

Brush

Determines the color and pattern for filling graphical shapes on the layer. Set the Brush property to specify the color and pattern to use when filling in graphical shapes. The value of Brush is a TBrush VCL or FMX object. Set the properties of the TBrush object to specify the color and pattern or bitmap to use when filling in spaces on the layer.
 

HorizontalAxis

Represents property HorizontalAxis.

Image

Specifies the picture that appears in the layer. Use Image to specify the image for the TRSChartLayer object. Image is a reference to a TRSPicture object (TPicture in VCL and TBitmap in FMX). Use properties and methods of TRSPicture to specify a bitmap, icon, metafile, or user-defined graphic to be displayed by the chart layer. The     ImageMode property specifies how the Image will be drawn within the bounds of the chart layer.

Setting Image at design time brings up the Picture Editor, which can be used to specify the file that contains the image.
 

ImageMode

Controls how the Image is painted within the layer. See RSChartConsts|TImageMode for more information.

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.

Opacity

Represents property Opacity.

Pen

Specifies the kind of pen the chart graphic area uses for drawing lines and outlining shapes in the layer. Set Pen to specify the pen to use for drawing lines and outlining shapes in the layer. The value of Pen is a TRSPen object (TPen in VCL, and TStrokeBrush in FMX). Set the properties of the TRSPen object to specify the color, style, width, and mode of the pen

Transparent

Specifies whether the layer is transparent or not. If the layer is not transparent, it is filled with the   Brush before drawing any Image.

VerticalAxis

Represents property VerticalAxis.

Visible

Represents property Visible.

Zoomable

Specifies whether the layer is zoomable or not. If the layer is not zoomable, when you zoom the chart, the layer is still drawn as if unzoomed.

Assign(TPersistent)

Copies the contents of another similar object to the current object

Changed

Overloaded. Represents method Changed. (Inherited from RSChartPanel.TRSChartGraphic.)

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 RSChartPanel.TRSChartGraphic.)

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.

Draw(TCanvas,TCanvasRect,TRSChartAxis,TRSChartAxis)

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 RSChartPanel.TRSChartAxis ).

Drawing(TCanvas,TCanvasRect)

Represents method Drawing(TCanvas,TCanvasRect). (Inherited from RSChartPanel.TRSChartGraphic.)

Drawn(TCanvas,TCanvasRect)

Represents method Drawn(TCanvas,TCanvasRect). (Inherited from RSChartPanel.TRSChartGraphic.)

Initialize

Represents method Initialize. (Overrides RSChartPanel.TRSChartGraphic.Initialize.)

InitializeEvents

Represents method InitializeEvents. (Overrides RSChartPanel.TRSChartGraphic.InitializeEvents.)

InternalDraw(TCanvas,TCanvasRect)

Represents method InternalDraw(TCanvas,TCanvasRect). (Overrides RSChartPanel.TRSChartGraphic.InternalDraw(TCanvas,TCanvasRect).)

SenderChanged(TObject)

Overloaded. Represents method SenderChanged(TObject). (Inherited from RSChartPanel.TRSChartGraphic.)

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.

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.

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.

VisibleChanged

Represents method VisibleChanged. (Inherited from RSChartPanel.TRSChartGraphic.)

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 RSChartPanel.TRSChartGraphic.)

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 RSChartPanel.TRSChartGraphic.)
