[Matplotlib-users] mplot3d stays?

Hi, I have quite general question. Since mplot3d now back in matplotlib, the question is: is it going to stay there? Or is it some test release? I was just wondering cause sometimes I use 3d plotting and use Mayavi2 for that but in many cases it's like killing the spider with a shotgun, not men

[Matplotlib-users] mplot3d: large numbers scatter plot

Hi, I was hoping to use mplot3d to visually examine the density of points in a 3D plot. However, the number of points i am displaying is of the order 10,000-100,000. I use scatter or scatter3D to plot x,y,z for the points. The pan and zoom functions become unworkable. Does anyone have any bright

Re: [Matplotlib-users] mplot3d bar3d errors

Thanks Reinier, Yes, upgrading to 0.99.1 seems to have fixed the problem. One slight oddity: the package I downloaded from the SF page linked at [2] had a filename of matplotlib-0.99.1.2.tar.gz however inside the tarball is a directory named matplotlib-0.99.1.1 and the PKG-INFO file also says 0.99

Re: [Matplotlib-users] mplot3d bar3d errors

Hi Derek, I just tried your program with the latest svn version and that seems to work fine, so I'd suggest you try that as well [1]. It looks to me like the fix should be present in 0.99.1-2 too [2]. Please let me know if you still run into the same problem. Cheers, Reinier [1] http://matplotl

[Matplotlib-users] mplot3d bar3d errors

Hi all, I'm getting strange errors trying to use the bar3d method in mplot3d (I'm using matplotlib 0.99.0 in Ubuntu 9.10 and Python 2.6). I'm doing something roughly like the example at http://matplotlib.sourceforge.net/examples/mplot3d/hist3d_demo.html I've pasted my sample program below, which ha

Re: [Matplotlib-users] mplot3d scatter3d marker sizes?

Hi Erik, I can reproduce your finding on my site. Maybe this kind of specifying the coloring is not yet fully supported. I think Reinier Heeres is the one how knows almost everything about mplot3D - maybe he can comment on this. Kind regards, Matthias On Wednesday 20 January 2010 00:14:39 Erik

Re: [Matplotlib-users] mplot3d scatter3d marker sizes?

Apparently it wasn't recent enough - I updated to the latest svn and now they are sizing properly - thanks! Another oddity I've noticed, though - if I do ax.scatter3D(x,y,z,s=30*rand(20),c=rand(20)) I would expect to see the points colored based on a color map for the supplied scalar values. In

[Matplotlib-users] mplot3d scatter3d marker sizes?

Is there a way to change the sizes of scatter plot markers for mplot3d.Axes3D.scatter3d ? I do from mpl_toolkits.mplot3d import Axes3D ax = Axes3D(gcf()) x,y,z = randn(3,20) ax.scatter(x,y,z,s=30*rand(20)) and I expect to see 20 points of a range of sizes from 1 to 30... but instead I see them a

Re: [Matplotlib-users] mplot3d animations

Hi, Animations of 3d scenes is a bit tricky, because set_data() functions for wireframe and surface plots are not available. However, you can still do it by creating new surfaces or wireframes every frame, and removing the old one. I've attached an example that does this and will be added to svn s

Hi Matthias, I have a similar patch lying around somewhere, and I will try to apply it soon. I've been terribly busy lately, but I expect some nice mplot3d enhancements in the very near future. Regards, Reinier On Wed, Dec 2, 2009 at 4:22 PM, Matthias Michler wrote: > Hi Andrew, > > do you have

Hello, I would like to do animations of a 3d scene. Thus I would need do to animation of some mplot3d-generated plot. Has somebody already tried it ? Is it possible at all ? My first test don't work, but I never did an animation in matplotlib before. I would like to be sure this is not a dead end
