Re: [Matplotlib-users] Problem with matplotlib.colors.LogNorm
I think the problems with imshow and matshow of integer arrays are fixed now in svn. Eric Suresh Pillai wrote: So I been using the log scale provided by matplotlib.colors.LogNorm, but have been seing bizarre behaviour. Basically, high values are not displayed properly. I give simple examples below with just two possible values in the matrix, but all the same issues arise with more varied values. First notice that the high value (10) is displayed as being of value=1: from pylab import * from matplotlib.colors import LogNorm matrix = ones((30,30)) matrix = matrix*440 matrix[29,29] = 10 matshow(matrix, norm=LogNorm(vmin=1, vmax=100)) colorbar() show() The cutoff value for incorrect display (for the scale I am using) seems to be at 32000: from pylab import * from matplotlib.colors import LogNorm matrix = ones((30,30)) matrix = matrix*440 matrix[29,29] = 32000 matshow(matrix, norm=LogNorm(vmin=1, vmax=100)) colorbar() show() However, if the value is really high, the color displayed changes again, although still not to the correct color (please try with values 918000, 92, and 999000 to see see it progress): from pylab import * from matplotlib.colors import LogNorm matrix = ones((30,30)) matrix = matrix*440 matrix[29,29] = 918000 matshow(matrix, norm=LogNorm(vmin=1, vmax=100)) colorbar() show() And if one specifies no limits to LogNorm, the colorbar displayed is incomplete and the colour displayed is wrong in a different way then when specifying the limits (try value = 999000 as well). from pylab import * from matplotlib.colors import LogNorm matrix = ones((30,30)) matrix = matrix*440 matrix[29,29] = 918000 matshow(matrix, norm=LogNorm()) colorbar() show() Either I am completely missing something or there is a major bug.

[Matplotlib-users] question about standalone small software and teaching
Hello Dear All, I just have a question for all that uses python/numpy/scipy/matplotlib for making science. I use with no problem in my computer python+numpy+scipy+matplotlib and I'm very satisfied with them. I was a matlab user. I still not have unearthed the power ot python but I'm happy to use a programming language and not a metalanguage. When I gave people my software (in matlab) the all ask me if I could compile and create some interface. I tried to use matlab GUIs, succeded in creating, but then I had a lot of problems. Compiling not always worked. after compiling you have not a workspace and so I had to make all output as txt files... and so on. Now that I use python I'm again with the same problem. I create easy routines (for chemometrics) and then people ask me if I can make a standalone program with interface. I used orange and for NN it's surely one of the best, but I'm not good at programming widgets. Then I think about it, searched the web and didn't find anything. What I'm searching is something similar to labview :) At first I thought ... hey why people wat an interface, just use the console, and then after listening to their reason I have to agree. What do I generally do ? I have a matrix in txt, I apply my routines (a SVD, a PCA, a filter etc etc written in python), plot them (using maplotlib) and then I want an output. that's it. I started looking at various Qt etc. etc. but for me it's overhelming, because I think that the most important part should be dedicate to the routines creation and not to making a gui, compiling, etc. etc. I need simple command like people wants. grids, paste and copy, small working plots :) I mean I can get crazy with setting my program, importing etc. etc. but I also have to say that needs and claim about writing simple guis, common paste and copy etc should be considered from someone there (we wait for the help of some guru that makes things easier ;) thanks for reading the mail Giorgio - Take Surveys.

Re: [Matplotlib-users] question about standalone small software and teaching
First, Please don't cross-post quite so much. I've only sent this to the matplotlib list. Maybe the scipy-users would be better, but I'm not on that one. First: What you want to do really is hard. One of the reasons is that each app is going to have its own simple needs. Also, GUIS really do take a lot of work. I've written simple command line scripts, then found wrapping a GUI around them takes three times as long to write as the scripts took in the first place. Yes, it could be easier, but it's always going to be a lot of work. Second: Matlab is an expensive, proprietary application, thus, if you don't build a stand-alone, your users need to buy Matlab to use your code. Python/scipy/numpy/mpl are all freely re-distributable, so you don't' have that problem. Maybe your users don't really need a stand-alone, but rather need an easy to install and use environment for running your code, command line and all. Granted, there is no such complete package available at this point but there are efforts to make then, and you could also build your own. The Enthought build is good for Windows. Also be sure to check out qme-dev: http://sourceforge.net/projects/qme-dev/ It's not complete yet, but looks pretty promising. There are also efforts afoot to make it a bit easier to use py2exe, py2app, etc. for building stand-alones. If you really do want to build a stand-alone GUI tool, there are a lot of ways to make really full-featured GUIs, though you're right, it takes quite a bit of work. Given the state of affairs right now, I'd take a look at Dabo (it's not just for database apps): http://dabodev.com/ or PythonCard http://pythoncard.sourceforge.net/ And figure out how to integrate MPL with them (probably with wxMPL). Both of these projects seek to make it easier to build GUIs with wxPython, which I think is the best choice for cross-platform GUIs. Dabo, in particular, is oriented toward data-aware widgets, which could be a very good match for small scientific computation tools. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] - Take Surveys.

Re: [Matplotlib-users] Memory leak using matplotlib
Eric, Not much progress, I think. Memory leaks seem endemic to the gui backends, although Tk is by far the worst. I have been trying to understand the gtk case in the hope of discovering some simple change in mpl code that might eliminate the problem there and turn out to be applicable to the other backends as well. But I have not found the source of the problem, and it seems to occur even in a very simple test gui script using pure pygtk, with no mpl. I need to do more testing to find out whether the gtk problem is specific to use of gtk.Toolbar, or whether it will occur with any nested widgets. It seems that widgets are not getting destroyed completely; maybe there are some references lurking somewhere in the dark. With gtk, the garbage collector does not find any cycles that it can't deal with, but if I remember correctly from earlier testing, this is not the case with Tk. As a partial workaround, if you don't need the toolbar, try setting rcParams['toolbar'] = None This may make the leak much smaller. I think the toolbar causes problems in all guis simply because it increases the complexity and number of widgets being tracked, if for no other reason. I would be delighted if a gui guru would emerge with a thorough explanation and solution for the memory leaks occurring with repeated opening and closing of windows.

[Matplotlib-users] Numpy 1.0.2: some improvements for matplotlib
Hi there, A few months back, I complained about the slowness of the image function in matplotlib. One of the cullprit was a slow clip function; I've done a bit some work to improve the situation on numpy's side, efforts which were integrated in numpy 1.0.2. Now, when you clip a numpy array with scalar min and max values, you get a 5 to 30 fold speed-up; to get the maximum efficiency, you need inplace clipping (using the syntax a.clip(min, max, a) for a a numpy array). This makes image significantly faster (between 100 and 200 ms on recent computers), and I am sure in other functionalities of matplotlib as well. cheers, David - Take Surveys. Earn Cash.

Re: [Matplotlib-users] matplotlib and py2exe
Hello I saw your thread and I have a related problem. I use matplotlib (0.90.0.win32-py2.5) with wxPython (2.8-win32-unicode-2.8.3.0-py25). I use matplotlib with WXAgg and got the following error msg: This application has failed to start because wxmsw26uh_vc.dll was not found. Re-installing the application may fix this problem. The error msg appears on import _wxagg in the file backend_wxagg.py # try to load the WXAgg accelerator try: import _wxagg the msg appears here except ImportError: _wxagg = None I already had this problem with previous versions of both libraries. Thanks for any help Daniel -Original Message- From: Werner F.
