Thanks alot for the reply objo. I prefer to manipulate the axes. but the Minimum/Maximum seems to be ineffective after I drag the plot, no matter using the method
now I manually compare the scales on X and Y axes and change the ActualMaximum/ActualMinimum of one of the axes before plotting. but because I need to plot some spatial features to be shown as a map. i need to keep the same scale all the time. I am struggling
to keep the same scale on both axes when doing zooming. Do you have any suggestions?
Is it possible to implement a property setting the axes at same scale in the future. Thank you very much.
