TRSChartAxis.Pan(Integer) Method

Contents

Comments (0)

Moves the visual window, specified by the ZoomMinimum and ZoomMaximum properties, by the amount. The Amount parameter, which is based on pixels, is first converted into the equivalent amount based on chart axis values. Specifying a positive amount moves the zoomed window right and a negative amount moves it left.

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

The Pan method does nothing if the chart axis is not zoomed in ( Zooming = True).

Namespace: FMX.RS.ChartPanel

Delphi

public
procedure Pan( Amount: Integer ); overload;

Parameters

Amount

Type: Integer

The following example shows how to zoom and pan within the axis:

Delphi

begin
   // first, define the range of the axis
   RSChartPanel1.BottomAxis.Minimum := 0;
   RSChartPanel1.BottomAxis.Maximum := 100;

   // let's zoom the bottom axis to 25 to 75
   RSChartPanel1.BottomAxis.Zoom( RSRect( 25, 0, 75, 0 ) );
   RSChartPanel1.BottomAxis.UnZoom;

   // This is equivalent
   RSChartPanel1.BottomAxis.ZoomMinimum := 25;
   RSChartPanel1.BottomAxis.ZoomMaximum := 75;

   // now, lets pan the zoomed window to the right
   RSChartPanel1.BottomAxis.Pan( 10.0 );
end;
