Has anybody given any further thought to the implication of having Basemap set adjustable as "box-forced" instead of "box"? So far, it has been working just fine for me, but I have no clue if there are any unintended side-effects.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.

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 adjustable"box" (you can set box-forced in stead). -JJ On Tue, Jun 1, 2010 at 2:45 PM, Benjamin Root <ben.r...@ou.edu <mailto:ben.r...@ou.edu>> wrote: > > On a related note, I have noticed an incompatibility between AxesGrid and > Basemap.
