Hello, I was playing around with Mathematica the other day and was attempting to graph the modulus of the complex-valued gamma function. When I use a PlotPoints value of 120 the graph looks fine. However, the following command yields a corrupt graph (PlotPoints value of 150). Plot3D[Abs[Gamma[x + I y]], {x, -5, 5}, {y, -5, 5}, PlotPoints -> {150, 150}, PlotRange -> {0, 10}, BoxRatios -> {1, 1, 0.8}, AxesLabel -> {x, I y, Abs[Gamma[z]]}] Anyone know the reason for this and possible solutions? Thank you, Paul
