Sorry, it is "line_collection_2d_to_3d()".

 Well, there is the new 3D quiver feature:
 http://matplotlib.org/examples/mplot3d/quiver3d_demo.html. Not quite
 streamlines, but it might do in a pinch.

 Another approach:
 There is the 2d streamplot() function that returns a specialized
 object. From the docstring:
 ```
 Returns:

 *stream_container* : StreamplotSet
 Container object with attributes

 - lines: `matplotlib.collections.LineCollection` of
 streamlines

 - arrows: collection of
 `matplotlib.patches.FancyArrowPatch`
   objects representing arrows half-way along stream
   lines.
 ```

 You might be able to get away with using the "lines" object and feeding
 it through art3d.line_collection_2d_to_3d(), kind of like how it is done
 for pathpatch objects here:
 http://matplotlib.org/examples/mplot3d/pathpatch3d_demo.html. You
 might also be able to pass the individual objects in the "arrows" list
 through art3d.patch_2d_to_3d(), but I have no clue if that would actually
 work or not.

 I hope that helps!

Re: [Matplotlib-users] How to plot a 2d streamline in 3d view in matplotlib

2015-05-21 Thread Benjamin Root 
(keeping the discussion on the mailing list)

The object you get back have two attributes: "lines" and "arrows". This is
just psuedo-code, but it would look something like this:

```
stream = ax.streamplot(..)
art3d.linecollection_2d_to_3d(stream.lines, )
for p in stream.arrows:
art3d.patch_2d_to_3d(p, ...)
```
Again, I have no clue if this actually would work. I haven't tried doing
this myself.
