Ben Root Ben: To summarize the discussion so far, it seems that box-forced should not be used, and either Basemap should continue to use adjustable=box (for the reasons Eric gave in his post yesterday) or adjustable should not be set at all by Basemap and that job should be left to the user (since adjustable='box' is the default anyway, as Jae-Joon pointed out today). Perhaps it would help if you could provide a usage example for AxesGrid axes sharing with Basemap, so we can see what the consequences of changing the current behavior are. -Jeff Jeff, Maybe it isn't a use-case per se, but I have found that it is much easier to use axes_grid1 instead of subplots to produce multiple radar plots that all use the same colorbar. For example, I have 3 radar plots to show, and I want a single colorbar on the right-hand side. To a newbie, one would add three subplots with a .colorbar() command for the last one. Unfortunately, the newbie will discover that the third plot will be smaller than the other two because that last axes has to be split between two objects. To someone a little more advanced, you would create 4 subplots, but fool around with the size of the last axes (and also have to discover to use ColorbarBase instead of the regular colorbar call). But, with axes_grid, this is quite trivial and the results look very nice. This is a png image of a time series I recently included for a publication shows the result using AxesGrid: http://dl.dropbox.com/u/7325604/NWRT_TimeSeries.png Ben Root P.S. - I have found a 'bug' of sorts with using 'box-forced' for Basemap and AxesGrid. For the displayed plot, if one were to zoom in on one of the plots, the other plots will zoom in as well (which I think is neat), but they won't update their bbox to completely match the zoomed-in axes. I guess this would be an argument against using 'box-forced'? On Tue, Jun 1, 2010 at 6:00 PM, Benjamin Root ben.r...@ou.edu wrote: Right, that is sort of what I am asking. My thinking is that Basemap could use 'box-forced' instead of 'box' for the adjustable parameter in order to make it and AxesGrid compatible. Usually, if one wants to use AxesGrid, they all should have the same domain and aspect ratio. I just have no clue what sort of repricussions that has for other use cases. So far, this has worked just fine for me, but I hardly represent the normal use cases of Basemap and AxesGrid.

You need to somehow avoid the set_aspect call with adjustablebox (you can set box-forced in stead). -JJ On Tue, Jun 1, 2010 at 2:45 PM, Benjamin Root ben.r...@ou.edu wrote: On a related note, I have noticed an incompatibility between AxesGrid and Basemap. It appears that Basemap will explicitly set adjustable='box' when it calls ax.set_aspect(), but AxesGrid will error out, saying that it has to be 'datalim'.

Suppose I have a figure canvas with 3 plots... 2 are images of the same dimensions plotted with imshow, and the other is a scatterplot. I'd like to be able to link the x and y axes of the imshow plots so that when I zoom in one, the other zooms to the same coordinates, and when I pan in one, the other pans as well.

By default, x-axis is shared along the axes in a same column and
y-axis is shared along the axes in a same raw. i.e., in your example,
only the y-axis are shared which I think is the source of your issue.
http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/overview.html#axesgrid
I think what you want is to use share_all=True.
grid = AxesGrid(fig, 111,
nrows_ncols=(1, 3),
axes_pad=0.1,
share_all=True,
cbar_mode='single',
cbar_pad=0.05,
cbar_size=0.08,
)
Is this solve your problem?

Thanks Jae-Joon: Since I couldn't see any problem with removing
adjustable='box' from Basemap, I went ahead and did it (and added an
example that uses AxesGrid). AFAICT, a problem will only occur if the
user explicit does ax_set_adjustable('datalim').
