Re: [Matplotlib-users] AxesGrid problem.

[Ryan N. <rya...@gm...>]

Thank You,
I think I have a better understanding. In my figure, there are six axes,
three for the plots: grid[i] and three for their colorbars:
grid.cbar_axes[i].
I changed my code as you suggested and got something like:
[image: UKM0g.png]
I tried all sorts of things, but finally, by setting aspect=False I got it
to work. In the documentation, the table says this defaults to True and the
explanation of aspect below says it defaults to False. Although I don't
entirely understand what is going on, I think this threw me off.
So then I had this:
[image: 84Kna.png]
... which looks much better, except that there are two sets of x and y axis
labels? This seems to have something to do with the colorbar. I've got:
                    label_mode = "L",
                    cbar_location="right",
                    cbar_mode="each",
                    cbar_size="2%",
                    cbar_pad="0.5%"

Now I'm trying to get scales and labels on my colorbars.
I tried:
for i,parameter in enumerate(z_dim):
    ax = my_grid[i].pcolor(x_grid,y_grid,z_dim[parameter]) # This is the
pcolor plot
    my_grid[i].set_ylabel('Depth') # Correctly puts a y label on every plot.
    cb = my_grid.cbar_axes[i].colorbar(ax) # Puts in a colorbar for this
axes?s
    cb.set_ylabel(parameter) #It would be nice if this was on the far right
next to the colorbar. I don't see it anywhere. Perhaps underneath something?
[image: DPkWz.png]
It looks like perhaps the colorbar axes is inside the ax axes rather than
besides it?
In the demo_grid_with_each_cbar<http://matplotlib.sourceforge.net/examples/axes_grid/demo_axes_grid.html>example,
how would you put a scale and label on the colorbar like in this
plot:?
[image: 58dFK.png]
I can put a y_label on each contour plot, but since they all have depth, I'd
like to label this only once.
Is there a way to label the entire AxesGrid (or is that subplot?)?

Thank you very much for your help,

-Ryan
