Ok, I'll go for Mayavi. I am reasonably impressed by the demos. I haven't been to far into the documentation and I hop I won't regret my choice. But it looks great so far. Thanks for your help !! -Etienne Etienne Gaudrain wrote: > Hello list ! > > This is probably a recurrent topic, or even

Waouuuh ! These screenshots look awsome ! A shame this package is not in my Ubuntu repository. I'm a bit lazy, and I want a long-term solution, which supposes auto-update... -Etienne Andy Buckley wrote: > > You might also be interested in Nicholas Rougier's SciGL project, which > (IIRC) was st

Re: [Matplotlib-users] 3D plots

Thanks Barry. I still don't know whether I want to use Gnuplot.py or Mayavi. Gnuplot is built on a very stable base, so I would be sure to have few surprises with future developments. But maybe it is too old and will not pass the Python3k step... I gave a look to Mayavi, and the start is prett

Re: [Matplotlib-users] 3D plots

Thanks for all these pointers! I am well aware and respectful of the open source philosophy, and please do not see a criticism toward the work of the developers in my e-mail... just a lost user seeking advice, wanting to understand what happened to catch the train I apparently missed during the

Re: [Matplotlib-users] 3D plots

Thanks a lot for the link, and for the suggestions! I will probably give a go to Mayavi2, but given how heavy it seems to be (compared to matplotlib) it probably requires some custom wrapping... which means again a lot time investment... thanks for the tips anyway! Cheers, -Etienne Gary Ruben

Hi Etienne, Sorry to hear about your disappointment. You can read about the attempt to resurrect the 3D plotting capabilities here: Unfortunately, this doesn't help you right now. Depending on the type of 3D pl

Hello list ! This is probably a recurrent topic, or even more probably HAVE been a recurrent topic... So sorry, sorry, sorry... I wanted to search the archives but Sourceforge is very slow today (...). Anyway, here is my question: Is it right that Matplotlib can no longer plot 3D graphes? The

[Matplotlib-users] 3d + log

Hi all, Is there a way to define logarithmic axes when using axes3d ? lines like ax = axes3d.Axes3D(fig) ax.semilogx() or ax.set_xscale('log') fail ! Thanks, yves -- (o o) oOO--(_)--OOo--- Yv

[Matplotlib-users] 3D histogram

Hi, I would like to generate (or simulate) 3D histogram... How I can do this with matplotlib/pylab (if I can) ? I tried different ways : - 2D histogram in 3D but the result is not usable for me (because I have lot of small bars) - generation of bars with, for each bar, 5 Polygons but I didn't

[Matplotlib-users] 3d filled triangle (polygon)

Hi , I am trying to plot a filled triangle (or if possible any filled polygon) in 3D. I am afraid, I am missing something very basic here. I'd like to do something like: x=[0,1,1] #coordintes of the three corners y=[0,0,1] z=[3,8,1] ax.plane(x,y,z,facecolor='r') So far I tried the "plot_surfac

[Matplotlib-users] 3d graph combined with a 2D contour

Hi people Using the axes3d functionality, I am able to create 3D graph of desired mathematical functions ala the cookbook example. However, it would be useful to be able to have a 2D contour plot upon the xy plane of a graph at the same time. I've googled to no avail and wondered if someone

[Matplotlib-users] 3D plot tick labels overlap axes

When I updated from Matplotlib 0.90 to 0.90.1 the axis tick labels started overlaping the axes themselves. In 0.90 they are slightly offset and are readable, but in 0.90.1 they are very hard to read. Is there some way I can fix this easily? I guess I can roll back to 0.90 since I don't seem t
