Description

|
Assign(TPersistent)
|
Represents method Assign(TPersistent). (Overrides RSCharts.TRSCustomLineChart.Assign(TPersistent).)
|
![protected method protected method](protmethod.gif)
|
CreateChartValues
|
Creates the RSChartPanel.TRSChartValues class for the Values property
Notes to Inheritors
|
Override this method to create your TRSChartValues descendant
|

|
CreatePointsInfo
|
Creates the default PointsInfo object
|

|
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

DrawGlyph(TCanvas,TRSChartValue,TCanvasRect)
|
Represents method DrawGlyph(TCanvas,TRSChartValue,TCanvasRect). (Overrides RSChartPanel.TRSCustomChart.DrawGlyph(TCanvas,TRSChartValue,TCanvasRect).)
|
![protected method protected method](protmethod.gif)
|
DrawPoint(TCanvas,TCanvasRect,TRSPointChartValue)
|
Draws one point at the specified rectangle

|
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 RSCharts.TRSCustomLineChart.GetChartType.)
|

|
GetColor
|
Represents method GetColor. (Overrides RSChartPanel.TRSCustomChart.GetColor.)
|

|
InitializeChangeEvents
|
Initialize the OnChange events of structures. Use this method to assign event handlers for structures (e.g., Pen.OnChange := MyChangeMethod).
Notes to Inheritors
|
The constructor calls this method after it calls the InitializeChart method, which is where the structures should be actually created and initialized.
|
|

|
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)
|
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.

Notification(TComponent,TOperation)
|
Represents method Notification(TComponent,TOperation). (Overrides RSChartPanel.TRSCustomChart.Notification(TComponent,TOperation).)
|

|
SetCanvasResources(TCanvas,TRSChartValue,Boolean,Boolean)
|
Represents method SetCanvasResources(TCanvas,TRSChartValue,Boolean,Boolean). (Overrides RSChartPanel.TRSCustomChart.SetCanvasResources(TCanvas,TRSChartValue,Boolean,Boolean).)
|

|
SetColor(TCanvasColor)
|
Represents method SetColor(TCanvasColor). (Overrides RSChartPanel.TRSCustomChart.SetColor(TCanvasColor).)
