Dear Mathgroup, When I plot a 3D plot in mathematica, I found that some part of the surface has been cut off in the graph. For example, z = x^5*y Plot3D[z, {x, -1, 1}, {y, -1, 1}, PlotPoints -> 40, Mesh -> False, BoxRatios -> {1, 1, 0.4}] Mathematica plot for z values only in the range -0.2 to 0.2. Actually when x=1, y=1, z value will be 1. But in the graph, the surface goes flat for z>0.2.Why? How can I get the graph for full range of z?
