mplot3d update

Reinier_Heeres1 · June 8, 2009, 4:33pm

Hi John,

Hi all,

I just updated mplot3d with some refactoring, more examples and the
start of documentation. Also semi-3D text is available again.

Great -- I made a minor change to special case atan2 with inputs 0,0,
which raises an error on my solaris box. I took a look at the
documentation commit -- I see the reference

See :ref:`toolkit_mplot3d-index` for more documentation and examples.

in docs/users/toolkits.rst, but there is nothing in doc/mpl_toolkits.
Did you forget to svn add the file?

Oops, they are there now.

One other feature request that I think you could add w/o too much
difficulty is colormapping on the surface plots (eg inherit from
cm.ScalaraMappable. I did this in a local branch of the old axes3d
code which I might be able to dig up, but I think it should be pretty
forward to implement de novo.

I've been thinking about this too. It would be great if you could dig
this up as an example! (I haven't looked at ScalarMappable yet, so it
might indeed be relatively straightforward). I was also thinking about
a sort-of pcolor3d or voxel generation although I'm not sure how to
best implement it. But maybe allowing the surface plots to be colored
is enough.

Regards,
Reinier

Please let me know what you think, perhaps mostly about the
user-facing API. It would be good to get that 'right' so that we don't
have to change it in the future.

You may want to take a look at what other popular toolkits do:
gnuplot, matlab, vtk. These are time worn implementations so we could
benefit from seeing what they've done for the interface.

The exclude-members tag is causing problems for my build
(.Sphinx-0.6dev_20090302-py2.5.egg) I don't know if the usage is too
new for my sphinx version but this line

./mpl_toolkits/mplot3d/api.rst: :exclude-members: contour3D,
contourf3D, plot3D, scatter3D

is causing the following error listed below. For now I am just
removing the exclude-members line.

http://matplotlib.sourceforge.net/mpl_toolkits/mplot3d/index.html#toolkit-mplot3d-index

w/ the exclude-members tag I am getting::
