Stylistically, throughout this PR it would be preferable to not put spaces between function/method keyword argument definitions. e.g.

cset = ax.contour(X, Y, Z, zdir='z', offset=-100, cmap = cm.coolwarm)

becomes

cset = ax.contour(X, Y, Z, zdir='z', offset=-100, cmap=cm.coolwarm)

cset = ax.contour(X, Y, Z, zdir='x', offset=-40, cmap = cm.coolwarm)
cset = ax.contour(X, Y, Z, zdir='y', offset=40, cmap = cm.coolwarm)

ax.set_xlabel('X')
ax.set_xlim(-40, 40)
