Description
The ZoomRect method does zoom on Chart contents. The Rect parameter defines the pixel rectangle coordinates of the chart area to be zoomed. Calling this method is similar to manually drawing a zoom box at run-time by dragging the left mouse button.</sup>

^{You can perform a zoom in by specifying a Rect parameter enclosed on Chart dimensions, and zoom out by specifying a bigger rectangle parameter.}

^{Zoom in example:}

^Delphi

^{Chart1.ZoomRect( Rect( 5,5,Chart1.Width-5,Chart1.Height-5 ) );}

^{Visual Basic}

^{TChart1.Zoom.ZoomRect 5, 5, TChart1.Width - 5, TChart1.Height - 5}

^{Zoom out example:}

^Delphi

^{Chart1.ZoomRect( Rect( -5,-5,Chart1.Width+5,Chart1.Height+5 ) );}

^{Visual Basic}

^{TChart1.Zoom.ZoomRect - 5, - 5, TChart1.Width + 5, TChart1.Height + 5}
