matplotlib-users Mailing List for matplotlib

I wrote a program that draws grids manually on mpl plots a while back. If
you can't find a solution can you write back here and I'll try to get that
dusted off?

Well, the first part is easy... it is called twinx(). If you look up axis
twinning in the documentation, you will find a lot of examples of this.
As for the grids part... that would be tricky. I would first just see if
matplotlib "just does the right thing". Doubtful, but who knows? Then I
would likely go the route of lining up the major ticks on both axes so that
the grid lines for one axes match up with the ticks for the other.
Let us know what you find out. Maybe it might be a useful feature to add
for twinning.
Cheers!

I need to overlay 2 different plots. They will share an x-axis, but will have 2 
different y axis with 2 different sets of units. I want one y-axis on left and 
one on right.
But to make it harder, I want a grid. That means, there are either 2 different 
grids, which is ugly, or one plot has to be scaled vertically so that the same y 
grid can be shared between them.
Anyone know how to do this?
