pcolormesh and clim?

Hi all,

In 1.2.0:

pcolormesh(x,z,U,rasterized='True',cmap=cm.RdBu_r,clim=(-1.,1.))
#clim((-1.,1.))

Doesn't seem to work, where as

pcolormesh(x,z,U,rasterized='True',cmap=cm.RdBu_r,clim=(-1.,1.))
clim((-1.,1.))

does work. Is this a bug or am I misunderstanding "clim" in the context of pcolormesh?

Thanks, Jody

Jody,

There is no clim kwarg, only a clim pyplot function. You can do this, though:

pcolormesh(..., vmin=-1, vmax=1)

Hi Eric,

The docs seem to indicate "clim" is an acceptable kwarg, hence my confusion...

Jody,

You are right, that chunk of the docs is completely fouled up with respect to kwargs. Thanks for pointing it out. The whole table of supposed QuadMesh properties should not be there. Doc autogeneration has run amok here. Pay attention only to the listed keyword arguments above that table.

Sounds good....

OTOH a clim argument for pcolormesh would be nice, as I often end up calling "clim" after I've made a contour overtop of my pcolor, and then call clim, which is obviously not what I mean to do, but...

Thanks, Jody

The problem is that it would be entirely redundant, given the vmin and vmax kwargs that have been there for a long time. I see your point, but we can't get rid of vmin and vmax (they provide more flexibility than clim would), so I think that the clutter disadvantage of adding clim outweighs the advantage.

Fair enough - I just often play with symmetric axis limits (i.e. [-1.,1.]) and so its helpful to be able to specify as an array and do something like clim = array([-1.,1.])*0.2 (for instance). Of course matplotlib probably has some other fancy way to rescale the vmin and vmax simultaneously...

Thanks a lot, Jody
