[Matplotlib-users] How do I use a grid geometry manager in a matplotlib tk backend
Hi matplotlib list, I am a resonably experienced python and matplotlib user, when it comes to make cmd line programs for batch processing, but I have never tried to make python GUI before. I am working on a prototype product, where I want the typical matplotlib plotting window, but extended with controls, such that I can control certain parameters determining what is being plotted. I have looked at the embedding_in_tk.py example http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_tk.html which uses the pack manager. That example works like a charm for me, and it seems like i should be able to extend it for my needs I have also managed to add controls to that using the Tkinter module and pack(), i.e., the tedious to maintain pack manager However, I would really like to use a grid geometry manager instead as I find it much easier to manage. I have therefore tried to modify the example to use grid instead by moifying the two pack lines in the example ... #canvas.get_tk_widget().pack(side=Tk.TOP, fill=Tk.BOTH, expand=1) canvas.get_tk_widget().grid(row=0) ... #canvas._tkcanvas.pack(side=Tk.TOP, fill=Tk.BOTH, expand=1) canvas._tkcanvas.grid(row=1) ... However, when I try to run that code, I just get an empty form I have tried other options in the grid method, with no success. I am sure i must be missing something obvious? Admittedly, these backend things are close to voodoo for me, so i am just trying to get a prrof of concepts, but i would not claim that i really undertsnad what is going on. I have tried to look for useful documentation for doing these kinds of things, but I have had only limited success. Directions/links to relevant material would be appreciated as well.

[Matplotlib-users] get current line cycle (color cycle), how to
Hello all, Does anyone know how to get the current line cycle or color cycle for a particular line. I'm plotting a collection of lines on 2 axes. After I finish plotting on the 1st axis, I then want to plot on the 2nd axis and resume where the line color left off in the 1st axis but so far I resets to the first line color in the color cycle. LMK if anyone knows how to set this. I've been digging on the website but don't have much luck.

Re: [Matplotlib-users] Problem with plotting fast spiking data
Just to conclude the problem. I've just installed a fresh svn matplotlib (1.0-svn to be exact) and the problem with path optimisation disappeared, meaning with path.simplify False plots are correct as far as my data is concerned. BTW it very nicely builds out-of-the-box on 10.6 in 64-bit mode.

For raster formats the workaround is to save the data in higher resolution, using DPI option. Below I included links to examples. This sounds like a problem with the path simplification algorithm. If so, the question is whether it is a bug that has been fixed or a new bug. What mpl version are you using? Can you build and install from svn?

I've experimented with different backends and the problem is persistent on GUI and 'file-writting' back ends. I also tested it on Linux and Mac, and the outcome does't change. Creating larger figures sometimes helps a bit but not always solve the problem. Just to mention that plotting this kind of data is possible 'out of the box' in Matlab or XPPAut (which is not the most fancy plotting tool) I get a proper outcome. Maybe there should be a option to plot raw data in some sense, or join style function that deals with such a plots in a proper fashion. If you need some additional information do not hesitate to ask.

[Matplotlib-users] figure save problem

When I try to save a figure, in the Save the figure dialogue box, the Save As: window does not recognize any keyboard entries. If I copy and paste, that works (at first). But I remembered reading about this problem people were having with Snow Leopard. Originally, copy/pasting worked to workaround this problem, but I find that after trying a few other things, I can no longer even paste anything into the Save As: Box. Further, when I click the Save or Cancel buttons, they flash like normal, however the dialogue box does not go away, the file is not saved, and I can't escape! Ahh! I can still navigate through my folders with the mouse in the dialogue box, but clearly something is not right. Last week, I had Python 2.5, matplotlib 0.98.6 and everything worked just fine.

Now that I've written this, I really should go and look and see if I remember correctly: I've found this: http://scikits.appspot.com/delaunay Though I see no reference to license in there, so I presume it's under the same license as scipy. So I guess I was thinking of the natgrid toolkit, which I guess is not Robert's work, and is a substitute for nn interpolation, not triangulation. Sorry for writing too quickly.

Originally, copy/pasting worked to workaround this problem, but I find that after trying a few other things, I can no longer even paste anything into the Save As: Box. Further, when I click the Save or Cancel buttons, they flash like normal, however the dialogue box does not go away, the file is not saved, and I can't escape! Ahh! I can still navigate through my folders with the mouse in the dialogue box, but clearly something is not right. Last week, I had Python 2.5, matplotlib 0.98.6 and everything worked just fine.

Re: [Matplotlib-users] Contour Plotting of Varied Data on a Shape

Yes, it would use the existing delaunay code by default, and hopefully optionally use the not-as-good-a-license code the Robert Kern put in SciPy. I did what now? I thought you'd put a wrapper of a delaunay code that is GPL'd or something (not BSD compatible anyway) into a scikit or something? optional -- so it doesn't screw up licensing for those that don't want it. Anyway, the point is, for any code that might be put into MPL, we want a properly licensed compatible default, but ideally with the option of easily plug in in other, better, delaunay code that may not be license compatible. Now that I've written this, I really should go and look and see if I remember correctly: I've found this: http://scikits.appspot.com/delaunay Though I see no reference to license in there, so I presume it's under the same license as scipy. So I guess I was thinking of the natgrid toolkit, which I guess is not Robert's work, and is a substitute for nn interpolation, not triangulation. Sorry for writing too quickly. Instead of addressing the misconceptions point by point, let me just lay out the situation: natgrid is a GPLed library for doing Delaunay triangulation and natural neighbor interpolation. The author is presumed to be deceased, so this code will always be GPLed. It seems to fail less often when doing the Delaunay triangulation on datasets in the wild; however, it is not using robust geometric primitives, so there probably still are cases where it fails. I wrote a BSD library for doing natural neighbor interpolation using the Delaunay triangulation code using the sweepline algorithm. This algorithm does not (and cannot) use robust geometric primitives, so there are datasets for which it fails to produce a valid triangulation. This is the code in scikits.delaunay. I have not pushed it to a 1.0 release because of this issue. However, this *was* put into matplotlib. matplotlib can optionally use natgrid if it is installed. While I've got your attention, though -- I suspect you have looked for license compatible delaunay code and the stuff in the scikits package is as good as it gets? Pretty much. I do have some code for constructing the Delaunay triangulation using robust primitives and an insertion algorithm, but it is an order of magnitude slower than scikits.delaunay. Ideally, we would be able to find or write a divide-and-conquer algorithm using Jon Shewchuk's robust geometric primitives. -- Robert Kern I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth. -- Umberto Eco -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

[Matplotlib-users] Yet another Tk backend
Hello, I just uploaded just another Tk backend for matplotlib. It can connect to any Figure instance, also with multiple Axes (although only one will be active for interactive zooming and panning). I hope the package is useful because of its special mouse usage. To pan, click right, hold, and pan. To zoom, click left, hold, and pan. To auto-zoom, click double-left. To open a window for adjusting title, xy labels, limits, and also for saving the figure to hdd, click double-right. I attach an screenshot of the settings dialog to attract some attention ... You can download from github.com/friedrichromstedt/matplotlib_backend_fr . Please find also the README there and the screenshot is also placed under Downloads. If anyone would like the package _and_ would have some wxPython knowledge or other widget packages, I would appreciate code for porting it to that widget platform. Currently only Tk is supported. But the framework is such that other widgets can reuse some parts of the implementation.

Re: [Matplotlib-users] contourf doesn't like a rectangular grid
I deem it useful if you would add a print map_XX.shape, map_YY.shape, y.shape . I'm suspicious about their shape. _check_xyz() accepts 2D X,Y-arrays only if their shape is equal to that of y (y in your case).

Re: [Matplotlib-users] Fixing Figure Size
I would suggest that you add the axes with: axes = figure.add_axes((left, bottom, width, height)) instead of .add_subplot(). I think you have too many subplots, it seems that the algorithm isn't designed for this. With .add_axes(), you can add more space. Note that you have then maybe to call the axes.plot() method directly, which may be an disadvantage or advantage, depending on you mood :-) hth, Friedrich -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Right now, public setter method is not supported for these attributes. While this is possible it is a bit tricky. I need to double-check but you need to change the dimension of not only the associated artist (e.g., lines) but also its container (offsetbox). The current design recommends you to create a new legend (by calling legend again) if you want to change its attribute. If this approach is not applicable, please describe your use case.
