expandingMethods

 

Name

Description

public method

Assign(TPersistent)

Represents method Assign(TPersistent). (Overrides FMX.RS.BarCharts.TRSCustomBarChart.Assign(TPersistent).)

protected method

CreateChartValues

Creates the FMX.RS.ChartPanel.TRSChartValues class for the   Values property

alert_noteNotes to Inheritors

Override this method to create your TRSChartValues descendant

public method

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)

noteNote

Set the Preview property to false to have the design-time sample values show up at run-time

protected method

DrawAverageLine(TCanvas,TCanvasRect,TRSHighLowAverageChartValue,THighLowAverageStyle,Boolean)

Draw the line for the average on the side of the bar

public method

DrawGlyph(TCanvas,TRSChartValue,TCanvasRect)

Represents method DrawGlyph(TCanvas,TRSChartValue,TCanvasRect). (Overrides FMX.RS.BarCharts.TRSCustomBarChart.DrawGlyph(TCanvas,TRSChartValue,TCanvasRect).)

protected method

DrawHLABar(TCanvas,TCanvasRect,TRSHighLowAverageChartValue,Boolean)

Draw the High/Low/Average Bar Shape

protected method

GetBarRect(TCanvasRect,TRSBarChartValue,TRSCustomChart,TRSChartValueType,TRSChartValueType,TRSChartValueType)

Returns the canvas rectangle in pixels for the bar value. (Overrides FMX.RS.BarCharts.TRSCustomSparseBarChart.GetBarRect(TCanvasRect,TRSBarChartValue,TRSCustomChart,TRSChartValueType,TRSChartValueType,TRSChartValueType).)

public methodClass member

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.BarCharts.TRSCustomSparseBarChart.GetChartType.)

protected method

InitializeChart

Creates and initialize structures and values of chart. This method is the safe place to initialize chart values without change events occurring.

alert_noteNotes 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)

protected method

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.

alert_noteNotes to Inheritors

The default InternalDraw method implementation assigns the     Brush, Pen , and Font to the Canvas.

protected method

WantsCaptions(TRSChartAxis)

Returns true if the chart prefers Captions over Values for its labels on the input Axis. This method provides a hint to the TRSChartAxis when LabelStyle is alsAutomatic. (Overrides FMX.RS.BarCharts.TRSCustomSparseBarChart.WantsCaptions(TRSChartAxis).)
