Description
|
|
Assign(TPersistent)
|
Represents method Assign(TPersistent). (Overrides FMX.RS.ChartPanel.TRSCustomChart.Assign(TPersistent).)
|
|
BuildPoints(TCanvasRect,Integer,Integer)
|
Creates an array of points for all the values in the chart and returns the FirstIndex in FI and LastIndex in LI.
|
|
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
|
|
|
DrawArea(TCanvas,TRS2DChartValue,TCanvasRect,TCanvasPixel,TCanvasPixel,Boolean)
|
Draws the area under the line for that line segment
|
|
DrawLine(TCanvas,TCanvasRect,Boolean)
|
Overloaded. Draws the entire line for the chart. The method calls other methods depending on the LineStyle.
|
|
DrawLine(TCanvas,TRS2DChartValue,TCanvasRect,TCanvasPixel,TCanvasPixel,Boolean)
|
Overloaded. Draws the line for the line segment (from last point value to this point value)
|
|
DrawSmoothline(TCanvas,TCanvasRect,Boolean)
|
Draws the smooth line for the entire values collection (i.e., the LineStyle is lsCurveInterpolation or lsCurveApproximation). If the LineStyle is lsCurveInterpolation, it uses the DrawSmoothSegment method for each segment of the line.
|
|
DrawSmoothSegment(TCanvas,TRS2DChartValue,TCanvasPoint,TCanvasPoints,Boolean)
|
Draws a smooth line segment using the SegmentPoints. The Line is assumed to touch all the segment points (i.e., the LineStyle is lsCurveInterpolation)
|
|
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.)
|
|
GetPoints(TCanvasPoint,TCanvasPoint,TCanvasRect)
|
Returns an array of points from StartPoint to EndPoint based on the LineStyle and LineChartElements
|
|
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.
|
|
|
SetOptions(TChartOptions)
|
Represents method SetOptions(TChartOptions). (Overrides FMX.RS.ChartPanel.TRSCustomChart.SetOptions(TChartOptions).)
|
