mplot3d update

Development matplotlib-devel
1

Hi all,

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

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.

Regards,

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?

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.

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.

I'd very much suggest having a look at Mayavi's mlab interface too.
When Gael and Prabhu worked on it, they took strong inspiration in
mpl.pylab, to try to 'keep the spirit' of MPL while implementing high
level 3d support in mayavi, at a time when it seemed that MPL would
not have its own 3d. Now that this is changing, I think it would be
great if API-wise, MPL and Mayavi.mlab were as compatible as is
reasonable. This would make code reuse across tools much easier.

Reinier, I'm sure if you ping Gael he'd be happy to share some
thoughts with you, he's very interested in code reusability (he may be
on this list for all I know, but I did CC him just to be safe).

Thanks a lot for mplot3d!

Cheers,

I am around. :slight_smile:

Have a look at

for an overview on the mlab API.
You might also be interested in

for the reference of all functions.

Indeed, it would be great if mayavi.mlab and the 3D plotting module of
matplotlib were drop-in replacements, with regards to the simple API. We
really designed mlab's API looking at matplotlib's API and used the
similar API where possible.

Hi,

Could you please tell me how not to see the dashed line in the middle of 3d plotting scene? It’s also there on a saved png file as well.

Next, could it be possible to plot 3d box-whiskers plots via mplot3d interface?

Thanks…

I really appreciate your good work.

Hi,

I'm not sure what line you are referring to; do you mean the grid
lines? If not, please provide an image.

At the moment these lines can't be turned off, but it sounds like a
good plan to override the grid() function for that.

Hello,

Please see the uploaded image: http://img40.imageshack.us/img40/3909/dashedline.png

There is dashed line in the middle of the figure coming from the top of the plot. I didn’t mean grid lines, however would be nice to add a functionality like pylot’s x-yticks commands, ahh we also need zticks for your case :slight_smile:

Hi,

Could you post the code that resulted in this image? I don't see the
dashed line here if I use the example. If it is the example, do you
perhaps have some extra settings in your rc file(s)?

Hi,

I just fixed this issue and implemented setting/unsetting of the grid.
I also added a parameter axes3d.grid to matplotlibrc, which defaults
to True. Is that ok?

Ok, that strange line doesn’t show anymore. Thanks for the fix.

axes3d.grid works well from matplotlibrc file.

Could you tell me how to import axes3d module from within Ipython?

I get the following error when I try: (Seems to me something needs to be updated?)

In [3]: from matplotlib import axes3d

John,

Shall I update this file and change the error to say something like
"mplot3d is now available as a toolkit, use import
mpl_toolkits.mplot3d"?

The other option would be to just do a "from mpl_toolkits.mplot3d.axes3d".

Actually, I prefer removing axes3d from the matplotlib dir directly.
After the release, I will make sure it gets plenty of visibility in
the announcement and in the news box on the website main page.
Between that and the gallery, people will be able to find it.

So please just go ahead and remove lib/matplotlib/axes3d.py
