640 units on the x - Axis on Contour Graph but the auto scalling option is scalling upto 800 units which is undesirable whereas on the Y -Axis the auto scalling is working good exactly 480 units, I have tried with all the default options but unsuccessfulChange the tick spacing to be by units:
On the Axes property page, Tick Spacing sub page, click the "By Units" option and set Major units to 160 and Minor units to 40.
