Re: [Matplotlib-users] Single color transparent colormap

[Benjamin R. <ben...@ou...>]

The underlying mechanism is a pcolormesh(). The key thing to remember when
going back and forth between imshow and pcolors is that coordinates for
imshow refer to the center of the pixel, while coordinates for pcolors
refer to the corners, IIRC (I might have that backwards).
