TRSChartGraphic Class

Create

Initializes a new instance of the TRSChartGraphic class.

Destroy

Represents the destructor of the TRSChartGraphic class.

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

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.

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.
 

Assign(TPersistent)

Copies the contents of another similar object to the current object

Changed

Overloaded. Represents method Changed.

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.

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)

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 ).

Drawing(TCanvas,TCanvasRect)

Represents method Drawing(TCanvas,TCanvasRect).

Drawn(TCanvas,TCanvasRect)

Represents method Drawn(TCanvas,TCanvasRect).

FreeNotification(TObject)

Represents method FreeNotification(TObject).

Initialize

Represents method Initialize.

InitializeEvents

Represents method InitializeEvents.

InternalDraw(TCanvas,TCanvasRect)

Represents method InternalDraw(TCanvas,TCanvasRect).

SenderChanged(TObject)

Overloaded. Represents method SenderChanged(TObject).

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.

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.

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.
