Mar 9, 2016 · The cmap kwarg is the colormap that should be used to display the contour plot. If you do not specify one, the jet colormap (cm.jet) is used. You can change this to any other colormap that you want though (i.e. cm.gray). matplotlib has a …

I am trying to create a 2D Contour Map in Python that looks like this: In this case, it is a map of chemical concentration for a number of points on the map. But for the sake of simplicity, we could just say it's elevation.

Oct 16, 2020 · A simple way to visualize your 4D function, call it W(x, y, z), could be producing a gif of the cross-section contour plots along the z-axis. Package plot4d could help you do it. An example plotting an isotropic 4D function:
