[Matplotlib-users] Questions about 3D plotting
Hi,
First off, I'd like to congratulate the devs who wrote the 3D plotting
module. Its great and fits a lot of my plotting needs without
resorting to vtk, mayavi etc.
But I've had some issues with 3D plots
1. If i do a
import pylab as p
import matplotlib.axes3d as p3
fig=p.figure()
ax = p3.Axes3D(fig)
ax.scatter3D(ravel(x),ravel(y),ravel(z))
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
p.show()
then things work well.
But if I do an "from pylab import *",
the plot command does'nt work. Any ideas?
2. In the scatterplot, as well as other 3D plots, I would like to plot
different datasets with different colors. While in plot(), "r." etc
change color, in plot3d etc the option does'nt work.
So, is there a way to use different colors in the same plot.
3. Is there any documentation on the 3D plotting functions. There are
examples at http://scipy.org/Cookbook/Matplotlib/mplot3D, but I
could'nt find any documentation on function calls, options etc.
help(plot3d) just says plot3d(**args) without any other info.
cheers,
anirudh.

Perhaps you could > give a short explicit example of what used to work and now does not. - from pylab import * import matplotlib.axes3d as p3 fig=figure() ax= p3.Axes3D(fig) ax.scatter3D(x,y,z) show() - this causes an error. x,y,z are valid 1D arrays. They work using the method you've posted in your mail. Perhaps a wrapper can be wriitten around mayavi's mlab module. 3D plotting is too important to leave out of something like matplotlib. Its perfect for all other things. It would be a pity if one has to switch to gnuplot or dislin just for 3D. - Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

[Matplotlib-users] plotting numbers on axes in scientific notation
Hi, How can I plot numbers on the x and y axes in scientific notation? I have very large values on the y axis which I'd like to show as 1e9 and not 1 followed by 9 zeros. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
