I came across a problem and hope that you can help me.
I was trying to produce a contour plot of scattered x,y,z data, therefore I was using griddata. So far everything works fine, but when my mesh is too fine the following error message
appears and the script quits:
gnuplot (as of v4.2) only supports 3D filled triangular patches
Since the data is from a FEM software I have to plot it using a fine mesh to see the details. Does someone know a solution or a workaround to that?
