Zoom-GraphPage
Use these features to change the view of the graph page:
If you select View: Zoom In/ View : Zoom Out menu or use the hot keys Ctrl + I, to zoom in/ out the desired zoom location in the graph window, you need to click the location after you select the menu command or press the hot keys. After that, if you want to zoom in/ out further, you need to re-select the menu command or re-press the hot keys.
In contrast, the hot keys, Ctrl + M, Ctrl + mouse wheel, A key + mouse wheel and A + +/-, can zoom in/out on the desired zoom location consecutively.
