(Ultimately, I will obviously need to upgrade to 0.9, at which point I can report back on if this fixed the problem on my machine, but I can't do that until after the semester is over, mid May). I'm running MacPython 2.4.4. I've got matplotlib 0.87.7 w/TkAgg. I'm using IPython 0.7.4.svn.r2010, called with the -pylab flag. I'm running the tests reported here on a G5 (I've also seen them on a G4), using OS X 10.4.8. Belinda, I was not paying close enough attention and did not realize that you are all the way back at 0.87.7. I think that trying to do any kind of piecemeal updating of that to get 3d working decently is an exercise in futility; a lot of things have changed since then, some problems in 3d have been fixed but it still can't be considered operational, and Tim's recent work has been post-0.90, so upgrading to that is still not likely to be very satisfactory. A new release is planned soon--maybe next week?--and that would certainly get you closer. But overall, I think that trying to use mpl 3d functionality for a class this term is not a good idea. There is a lot you can do in 2d with 0.87.7; I think you would really be best advised to find a way to make that adequate for the purposes of your class this term. The easiest way to see some of the things that have changed is to go to http://matplotlib.svn.sourceforge.net/viewvc/matplotlib/trunk/matplotlib/ and browse the archive, especially lib/matplotlib, where the pure python parts are. 0.87.7 was released at revision 2835. You can also get an overview from CHANGELOG and API_CHANGES. Eric - Take Surveys. Earn Cash.

I'm kind of afraid to upgrade to the SVN version b/c I fear something else might break (I've yet to install matplotlib from source b/c of a few nagging Mac OS X issues). What would you recommend? I don't know; I see from your earlier message that Tim Leslie says some of the things you are trying to do are still broken, and his patches are what John committed, so svn is certainly no better than what Tim is working with now. I don't think that anything has changed since 0.90 in such a way as to require changing both the compiled parts and the pure python parts, so you could try simply replacing the pure python part. There's also the issue of having to upgrade student machines for which I'm not admin. Grrr. That certainly makes the prospect of doing any kind of upgrade less attractive. I don't have a good solution. --b On Apr 11, 2007, at 6:19 PM, Eric Firing wrote: Belinda, John has checked in some fixes for axes3d recently, and your test code now runs with the version in svn--except for the problem that you should use P.show() only once in a given script.

belinda thom wrote: Me neither :-). I will try and get permission to upgrade axis.py w/my quick fix commenting out the kwargs in line 2131 of axes.py, as this is the quick option and I need something ASAP. You seem to know quite a bit about matplotlib. If you have any idea what this hack might break, I'd appreciate your insight so I know what to be wary of. Your fix is rendering the scalex and scaley kwargs of Axes.plot ineffective, so that both axes will be autoscaled regardless of the value of these kwargs. It might have no practical consequence for what you are doing. The larger concern is that I can't figure out how making that change would be needed--the error message you show doesn't make sense to me, given what I see in the code, which means I don't understand something critical--and in fact this fix doesn't seem to be needed on my system. So, maybe this particular problem really has been fixed since 0.9, and Tim is referring to some other sort of problem in the 3d code. (I am simply assuming he is working from svn, but I don't know this for a fact.) All very confusing and unsatisfactory. Eric - Take Surveys. Earn Cash.

Re: [Matplotlib-users] 3D curve and errors in axes3d
Hi, I'm replying to this older thread http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/ msg02100.html because it relates very much to my recent problem, posted at http:// www.mail-archive.com/matplotlib-users@lists.sourceforge.net/ msg03037.html. This problem seems more general than just the two circumstances you mentioned. I'm finding the problem w/any use plot3D in matplotlib.axes3d, e.g.: import copy import pylab as P import matplotlib.axes3d as P3 fig = P.figure() ax = P3.Axes3D(fig) ax.plot3D(P.ravel(X),P.ravel(Y),P.ravel(Z)) # this command will fail with the errors identical to those you report. I modified matplotlib's axis.py in a similar way as your suggestion. Line 2131 went from: self.autoscale_view(scalex=scalex,scaley=scaley) to: self.autoscale_view() #scalex=scalex,scaley=scaley) It took me a while to verify that this fixed the problem b/c I didn't at first realize I'd have to kill ipython and restart it (so that it sees the new axes.py file). I wonder what this change to axes.py will break. Any ideas? Thx, --b - Take Surveys. Earn Cash.

Re: [Matplotlib-users] 3D curve and errors in axes3d
Belinda, John has checked in some fixes for axes3d recently, and your test code now runs with the version in svn--except for the problem that you should use P.show() only once in a given script. (I think there is some backend for which you can get away with using it more than once, but this is not good practice.)

Re: [Matplotlib-users] 3D curve and errors in axes3d
Hi, the same problem occurred, when I also tried to plot some chaos systems the solution I found (and works just fine) is to comment axes.py:2131 I didn't send a patch, 'cos I'm not sure that it wasn't really an common bug (I played with my overall python distribution) some OT: 1) trajectories - you could use pydoc numpy.hsplit 2) IMHO to plot chaotic behaviour with iterations over 500k the matplotlib on an ordinary computer is a little bit slow compared to creating a data file and using gnuplot ...
