TRSCustomChartPanel Methods

AxesPointToPoint(TRSPoint,TRSChartAxis,TRSChartAxis)

Converts axes coordinate to canvas coordinates using the specified X and Y axes. The AxesPointToPoint uses the TRSChartAxis AxisToPixel method. Unlike the AxisToPixel method which converts only the x value or y value, the AxesPointToPoint method converts a point to the canvas coordinates.

AxesRectToRect(TRSRect,TRSChartAxis,TRSChartAxis)

Converts axes coordinates to canvas rectangle coordinates using the specified X and Y axes. The AxesRectToRect method uses the TRSChartAxis AxisToPixel method. Unlike the AxisToPixel method which converts only the x value or y value, the AxesRectToRect method converts an entire chart rectangle to canvas rectangle coordinates.

Pan(Integer,Integer,Boolean,Boolean)

Overloaded.  Moves the visual window (or the zoomed window) that the chart panel displays. The zoomed area is not changed. By default, the Pan method uses the     BottomAxis and the     LeftAxis to pan. By changing the UseBottomAxis and UseLeftAxis parameters, you can change which axes are used. The MoveX and MoveY parameters, which is based on pixels, are first converted into the equivalent amounts based on chart axis values.

Specifying a positive MoveX amount moves the zoomed window right and a negative amount moves it left. Specifying a positive MoveY amount moves the zoomed window up and a negative amount moves it down.

Use the overloaded Pan method to move the visual window using chart axis values directly.

Pan(TRSChartValueType,TRSChartValueType,Boolean,Boolean)

Overloaded.  Moves the visual window (or the zoomed window) that the chart panel displays. The zoomed area is not changed. By default, the Pan method uses the     BottomAxis and the     LeftAxis to pan. By changing the UseBottomAxis and UseLeftAxis parameters, you can change which axes are used. The MoveX and MoveY parameters, which are based on chart values, specify the movement amount.

Specifying a positive MoveX amount moves the zoomed window right and a negative amount moves it left. Specifying a positive MoveY amount moves the zoomed window up and a negative amount moves it down.

Use the overloaded Pan method to move the visual window using canvas pixel values.

PointToAxesPoint(TCanvasPoint,TRSChartAxis,TRSChartAxis)

Converts a canvas coordinate to axes coordinates using the specified X and Y axes. The PointToAxesPoint uses the TRSChartAxis PixelToAxis method. Unlike the PixelToAxis method which converts only the x value or y value, the PointToAxesPoint method converts a point to the internal point coordinate.

RectToAxesRect(TCanvasRect,TRSChartAxis,TRSChartAxis)

Converts pixel rectangle coordinates to axes coordinates using the specified X and Y axes. The RectToAxesRect method uses the TRSChartAxis PixelToAxis method. Unlike the PixelToAxis method which converts only the x value or y value, the RectToAxesRect method converts an entire rectangle to the internal rectangle coordinates.

Resize

Represents method Resize.

ScreenToChart(TCanvasPoint)

Converts the screen coordinates of a specified point on the screen to chart panel coordinates. Use ScreenToChart to convert a point in screen coordinates to local, or chart panel area, coordinates. In chart panel area coordinates (0, 0) corresponds to the upper left corner of the chart panel's client area. In screen coordinates (0, 0) corresponds to the upper left corner of the screen.

Select(TCanvasRect,TRSChartSelectionAction)

Selects or deselects any chart values displayed within the SelectionRect. Use the Select method to select chart values within the SelectionRect.

SelectionColorChanged

Represents method SelectionColorChanged.

SenderChanged(TObject)

Overloaded. Represents method SenderChanged(TObject).

Unzoom(Boolean,Boolean)

Resets the visual window for the two chart axes to their full visual range (e.g.,   ZoomMinimum =   Minimum and   ZoomMaximum =   Maximum for both the horizontal and vertical axis). Usually, it unzooms the   BottomAxis and the   LeftAxis to change displayed area for charts associated with those axes. Set the UseBottomAxis parameter to False to use the   TopAxis and the UseLeftAxis parameter to False to use the   RightAxis.

UpdateChartColorScheme

Updates the Charts and their values (if Preview is True) to the current color scheme

UpdateLegend(TRSCustomChart,TRSChartValue)

Represents method UpdateLegend(TRSCustomChart,TRSChartValue).

ValueChanged(TRSCustomChart,TRSChartValue)

Represents method ValueChanged(TRSCustomChart,TRSChartValue).

ValueSelectionChanged(TRSCustomChart,TRSChartValue)

Represents method ValueSelectionChanged(TRSCustomChart,TRSChartValue).

ValueVisibleChanged(TRSCustomChart,TRSChartValue)

Represents method ValueVisibleChanged(TRSCustomChart,TRSChartValue).

VisibleChanged(TRSCustomChart)

Represents method VisibleChanged(TRSCustomChart).

Zoom(TRSPoint,Single,Single,Boolean,Boolean)

Overloaded.  Zooms the chart panel to desired point in chart coordinates. The magnification of the zoom area is specified by the ZoomX and ZoomY parameters, e.g., ZoomX/ZoomY = 2 means 2x magnification. A value less than or equal to 1 unzooms that axis.

Usually, this method zooms the     BottomAxis and the     LeftAxis to change displayed area for charts associated with those axes. Set the UseBottomAxis parameter to False to use the TopAxis and the UseLeftAxis parameter to False to use the     RightAxis.

Use the     ZoomPixelArea method to zoom the visual window by using a pixel coordinate rectangle of the chart panel's canvas. Use the     Zoom method to zoom the visual window by using a chart value coordinate rectangle directly.
 

Zoom(TRSRect,Boolean,Boolean)

Overloaded.  Zooms the chart panel to the desired rectangle. Usually, it zooms the     BottomAxis and the     LeftAxis to change displayed area for charts associated with those axes. Set the UseBottomAxis parameter to False to use the TopAxis and the UseLeftAxis parameter to False to use the     RightAxis. The Zoom method accepts a chart value coordinate rectangle and zooms the visual window to that rectangle.

Use the ZoomPixelArea method to zoom the visual window by using a pixel coordinate rectangle of the chart panel's canvas.

The Zoom method uses the TRSChartAxis.Zoom method to change the ZoomMinimum and ZoomMaximum properties of the specified horizontal and vertical axes.
 

ZoomPixelArea(TCanvasRect,Boolean,Boolean)

Overloaded.  Zooms the chart panel to the desired rectangle. Usually, it zooms the     BottomAxis and the     LeftAxis to change displayed area for charts associated with those axes. Set the UseBottomAxis parameter to False to use the TopAxis and the UseLeftAxis parameter to False to use the     RightAxis. The ZoomPixelArea method accepts a pixel coordinate rectangle within the chart panel, converts that rectangle to a chart value coordinate rectangle for the desired axes, and zooms the visual window to that rectangle.

Use the Zoom method to zoom the visual window by using a chart value coordinate rectangle directly.

The ZoomPixelArea method uses the RSChartPanel.TRSChartAxis .Zoom method to change the ZoomMinimum and ZoomMaximum properties of the specified horizontal and vertical axes.
