Scaling the Z Axis
Posted: Sat Mar 07, 2015 12:26 am
I am trying to plot the surface of a sphere.
The problem I'm having is the Z axis is not displayed using the same scale as the X and Y axes. The Z axis is about 1/2 the height of the X and Y axes for the same displacement. The result is an oblate spheroid (a football) rather than a sphere (a basketball).
How do I manually control the height of the Z axis?
If the equatorial diameter of the sphere is 6", I want the polar diameter to also be 6". Right now, Z is only about 3" (a 2:1 ratio).
Yes, the data set is correct.
Yes, the current display is technically correct but aesthetically unacceptable.
I have tried changing the extents for X and Y to no avail. I tried changing the aspect ratio of the window Dplot uses, to no avail. The software seems to rescale the Z axis whenever I change anything.
