Edgelines vanish in mplot3d surf when facecolors are specified

Question

I have produced the following surface plot in matlab:

and I need to create this in .N

Answer 1

You can put the lines in the surface plot adding the keyword argument edgecolors

# Add black lines in the edges
surf = ax.plot_surface(X, Y, volatility, rstride=1, cstride=1, facecolors= UWR(heatmap), linewidth=1, shade=False, edgecolors='#000000')

Directions over how to format the axis tick labels and locations here: http://matplotlib.sourceforge.net/api/ticker_api.html#matplotlib.ticker.FormatStrFormatter

Solved - Moved up from comments:

Adding surf.set_edgecolor('k') after plot_surface overrides the edge color. I think that may be related to the fact that facecolors is an option of plot_surface, but the edgecolors is an option of Poly3DCollection. More details here.
