How to create 3D plots?

Hi,

I would like to create 3D plots. A search revealed the following page:

http://www.scipy.org/Cookbook/Matplotlib/mplot3D

which explains to install matplotlib version 0.99 to use the 3D code.
Unfortunately, after installingmatplotlib-0.99.1.1 (from
matplotlib-0.99.1.2.tar.gz) I am not able to use the 3D code. The
command that show that the correct version is used together with the
error is shown below.

Any idea how I can use this code? Do I have to downgrade to the 0.91.x
maintenance branch? Or do you suggest to use mayavi
(http://code.enthought.com/projects/mayavi/docs/development/html/mayavi/mlab.html)?
I also tried to install the latter, after 1 hour of installing code
and requirements and cmake and easyinstall.. I got the error that VTK
is not installed. So: Any idea how to create a simple 3D scatter plot,
seen from any arbitrary angle?

Thanks
  Alex

Hello,

Unfortunately, the mplot3D page on the SciPy cookbook is not up to date.
The 3D code in mplot3d has been moved to a toolkit and needs to be imported as is seen in the examples found here:
http://matplotlib.sourceforge.net/examples/mplot3d/index.html

So: Any idea how to create a simple 3D scatter plot,seen from any arbitrary angle?

You can rotate the axis in mplot3d :slight_smile:

I would say from your error log (the file matplotlib/axes3d.py exists whereas it does not in my mpl 0.99.0) that you did not uninstall the old matplotlib cleanly. I suggest that you clean the existing matplotlib completely and reinstall from the tarball).
