Why is water leaking from this hole under the sink? Carcassi Etude no. I can't check the code without having the data, but I suspect that the problem is that you are using the default fill_value=nan as a griddata argument, so if you have gridded points that extend beyond the space of the (x,y) points, there are NaNs in the grid, which mlab may not be able to handle (matplotlib doesn't easily). So in my case, I assume it would be as following: ValueError: shape mismatch: objects cannot be broadcast to a single The scipy.interpolate.griddata() method is used to interpolate on a 2-Dimension grid.
