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.
