Zoom the axis in on (or magnify) a portion of the axis' range. The Zoom method accepts a rectangle using chart axis coordinates and changes the ZoomMinimum and ZoomMaximum properties to zoom the axis into that visual portion of the range. It allows you to change the portion of the axis that is being visually displayed.
The ZoomPixelArea method zooms the axis using canvas rectangle values instead of chart values.
