replaced gca(projection="3d") with plt.axes(projection="3d")

Replaced gca(projection="3d") with plt.axes(projection="3d") as is needed for matplotlib 3.4.2 and later.

The gca() command does not acept keyword arguments anymore.

Maybe I typed in my comment at the wrong place. Here we go again:

Thanks, but I think this might be a problem when you do 3D subplots and even more so on matplotlib 3.3. What seems to work with both matplotlib 3.3&3.4 and also with both standard plots&subplots is this:

PyPlot.version <= v"3.4" ? ax = gca(projection="3d") : ax = plt.subplot(projection="3d")

Ok, I changed it to your proposed version.
