color interpolation across the fairly large grid cells of your data is causing the "skewed" effect you are referring to. You can reduce that by using Refine to reduce the size of the grid cells before coloring.

All! I want to make a color shaded plot of a 2D data defined on a regular grid. The data has a symmetry plane which is parallel to y-axis. If I plot isosurfaces (contour lines), they show the correct symmetry. However, if I use color shading, the resulting image does not have the symmetry and looks rather distorted. I wonder if any of you can help me with this problem. Thank you. Hanchul Kim PS. Attached is the tar.gz file which contains the .net, .general and data files.
