X and Y label position in axes_grid1.AxesGrid/ImageGrid

Russell_Hewett · January 24, 2011, 7:56pm

Hi All,

I can’t get the x label on the top row of an ImageGrid to display if there is more than one row in the grid. I suspect that something is being clipped somewhere, but have no idea what to do to fix it. (Note, this also happens on the right edge of a ride-sided y axis label.)

I have included some minimal sample code below. I’d appreciate it if anyone can point me in the right direction.

Cheers,
Russ

Hi Russ,

thanks for the report - at a glance, it appears to be a bug in
AxesGrid removing redundant labels for shared axis when they
align. I've included a temporary workaround for your script, but
don't have time to look into it further at the moment. By the
way, calling grid[0].axes is redundant, so I just modified it to
use grid[0].xaxis, which is equivalent.

Isn't it a feature? Axes_grid lets you choose the label mode which is
'L' by default. This means that only the outer labels are shown. Or
am I missing something in the description of the problem?

This is indeed correct. Somehow I missed this. Setting label_mode = ‘all’ gets the behavior I wanted.

Though, the top and right side are technically on the outside too. Perhaps that should be an available or the default setting? Perhaps the top row should default to labeling on the top, the right column default to labeling on the right, etc?

As the mode name "L" implies, it means "left" and "bottom" side (of
the whole grid).

Maybe we can have an "outer" mode. Any contribution will be welcomed.
