Description
|
|
Assign(TPersistent)
|
Represents method Assign(TPersistent). (Overrides FMX.RS.ChartPanel.TRSCustomChart.Assign(TPersistent).)
|
|
CreateChartValues
|
Creates the FMX.RS.ChartPanel.TRSChartValues class for the Values property
 Notes to Inheritors
|
Override this method to create your TRSChartValues descendant
|
|
|
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
|
|
|
DoUpdateAxisInfo(TRSChartAxis)
|
Represents method DoUpdateAxisInfo(TRSChartAxis). (Overrides FMX.RS.ChartPanel.TRSCustomChart.DoUpdateAxisInfo(TRSChartAxis).)
|
|
DrawBar(TCanvas,TCanvasRect,TRSBarChartValue)
|
Represents method DrawBar(TCanvas,TCanvasRect,TRSBarChartValue).
|
|
DrawGlyph(TCanvas,TRSChartValue,TCanvasRect)
|
Represents method DrawGlyph(TCanvas,TRSChartValue,TCanvasRect). (Overrides FMX.RS.ChartPanel.TRSCustomChart.DrawGlyph(TCanvas,TRSChartValue,TCanvasRect).)
|
|
GetAdjOffsetVertical
|
Returns the vertical offset ( OffsetVertical).
If coUseVerticalOffset is not in Options, this method always returns 0. If coUseVerticalOffset is in Options, the function returns the OffsetVertical value.
|
|
GetAdjOrigin
|
Returns the adjusted origin for the bar chart. If the UseOriginproperty is set, this value is the Origin. If the UseOrigin property is false, the adjusted origin equals 0.
Note that when bar charts are stacked (see GroupStyle=gsStacked), the bottom-most bar chart adjusted origin is used as the origin for all the bar charts.
|
|
GetAxisCaption(TRSChartAxis,Integer,TRSChartValueType)
|
Returns a label for an axis ( FMX.RS.ChartPanel.TRSChartAxis ) based on the input Value. The Index specifies where to start looking in the chart Values (for optimization purposes) and decrements from there until the closest chart value is found. (Overrides FMX.RS.ChartPanel.TRSCustomChart.GetAxisCaption(TRSChartAxis,Integer,TRSChartValueType).)
|
|
GetBarRect(TCanvasRect,TRSBarChartValue)
|
Overloaded. Returns the canvas rectangle in pixels for the bar value
|
|
GetBarRect(TCanvasRect,TRSBarChartValue,TRSCustomChart,TRSChartValueType,TRSChartValueType,TRSChartValueType)
|
Overloaded. Returns the canvas rectangle in pixels for the bar value.
|
|
GetBarStyle(TRSBarChartValue)
|
Returns the bar style of the value
|
|
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.)
|
|
GetGroupDimension
|
Represents method GetGroupDimension. (Overrides FMX.RS.ChartPanel.TRSCustomChart.GetGroupDimension.)
|
|
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.
|
|
|
Notification(TComponent,TOperation)
|
Represents method Notification(TComponent,TOperation). (Overrides FMX.RS.ChartPanel.TRSCustomChart.Notification(TComponent,TOperation).)
|
|
UpdateAxisInfo(TRSChartAxis)
|
Represents method UpdateAxisInfo(TRSChartAxis). (Overrides FMX.RS.ChartPanel.TRSCustomChart.UpdateAxisInfo(TRSChartAxis).)
|
|
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.ChartPanel.TRSCustomChart.WantsCaptions(TRSChartAxis).)
