Hello,
I've got a surface plot of some X, Y, Z data that is correct. However, when I add contour lines (or do the 2D contour plot), there are extra contours that do not exist in my data. My Z axis should only have data from 200 to 1100, but in the picture, you can see data well below 200 into the negative values, and some data that exists above 1100. It appears mathcad is trying to interpolate data that isn't there to fill whitespace. When I fill the backplane, it only tints the contours that don't exist with the shade of the backplane fill.
Any fixes, or is this a glitch in 15?
Thanks
