[Matplotlib-users] pcolor - color values argument
Quote: matplotlib.pyplot.pcolor(*args, **kwargs) Create a pseudocolor plot of a 2-D array. C is the array of color values. I tried to see how can I map custom color values to example array, but seems hard to understand. I created 2x2 mesh, and appropriate C array for it. Changing values in this C array changes colors on plotted mesh in what it seems irregular way. Does C array map colors from default colormap? If yes, in which way they are plotted according values in this C array? Or how can I tell matplotlib to use this RGB value for this cell in a mesh, then another RGB value for other cell and so on Thanks -- RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

... just wanted to report this problem.
At the heart of the issue is the decision to have too many dependencies in
matplotlib (which is why I am posting here). That, although viewed as good
style, leads to an installation process that is, ultimately, practically
impossible - except by buying a prepackaged solution. (which is possible
but probably not the original intention)
What ultimately thwarts my installation attempts is the dependency on TeX.
While a good thing in principle, most packaging tools do not realize that
there is already a working TeX distribution there from another source, and
will only accept their own - which, in the case of debian/fink, can no
longer be postinstalled. It appears that I would have to uninstall and
reinstall my entire pre-existing setup just to get matplotlib to work.
Has anyone seen this problem before? Is there a workaround?

Hi Volker,
I have installed matplotlib with Fink. I had a similar issue, because I
didn't need to GTKAgg backend and didn't want to install all of the GTK+
packages that were required. I ended up making my own fink package called
matplotlib-py27-nogtk by editing the matplotlib-py.info and
matplotlib-py.patch files in my /sw/fink/10.6/unstable/main/finkinfo/sci
directory, to remove the dependencies and turn off the GTK+ check in
setup.py, respectively. I put the resulting files in
/sw/fink/10.6/local/main/finkinfo. You could try something like that,
although it's kind of messy.
There may also be a virtual fink package for TeX that doesn't install
anything, but counts as a proxy for a previous installation. If this is
true, it's a much better solution that what I did.
I hope this helps. If you need more info, I suspect that your question is
actually better suited for the fink-users list.
Good luck,
Jeff

Others are probably more suited for explaining the hows and whys of
mlab.py, but I will give it a crack. mlab.py was originally made to help
assist users transitioning from Matlab over to matplotlib. Some functions
that were probably considered to be top-tier in Matlab had to be accessed
in sub-modules in NumPy, or were only available in the scipy packages.
mlab.py attempted to address that.
There is also the issue where we were attempting to bridge compatibility
with the old Numerix package which did not have many of these things at
all. Support for Numerix has long been deprecated and so the need for many
of the functions in mlab.py has gone away. This is why we now refer to the
equivalent numpy function in the deprecation messages.
In v1.1.0, the norm() function is completely removed and you will not even
get a deprecation message at all. The easiest solution is to adapt your
scripts to use the numpy equivalents as suggested in the messages.
Cheers!

Volker, The simple answer to your question about safety is no, if safety in the long term requires that the code you write now must work with any future version of mpl. This is true throughout the software ecosystem of interdependent libraries--even in non-free software. It is particularly applicable to organically evolving libraries like mpl. We want the evolution of mpl to be as comfortable for users as possible, balanced with the need to improve. This includes the need to remove functionality that is marginal, obsolete, or inappropriate. All code has a maintenance cost. In addition, marginal or redundant functionality has a cost to users: increased learning time and likely confusion for anyone working with the library.

Re: [Matplotlib-users] Matplotlib.tests sub-modules missing
Hi Micheal, I didn't see your response, apologies for the frustrated post. I am building a completely fresh VE and when the testing fails I blow it away and start from scratch. I will try your suggestion on my next iteration and see if that fixes the problem. Ideally, I'd like to pip install the module into my VE, but the same problem persists with that approach.

Re: [Matplotlib-users] Triangulations and Polar Plots
On 15 November 2011 00:18, Daniel Welling dantwell...@gmail.com wrote: Greetings. I recently found myself in the position of needing to plot polar, irregularly spaced data. I've done similar using regularly spaced values with no problem. However, I've found that when the points become greatly scattered, the triangulation does not translate from rectangular to polar very well. Below, find a code example that shows this; though it is much better than my real-world case that uses simulation results. Essentially, in the translation from regular to polar axes, many of the triangles overlap others, many features of the plot are lost, and the plot looks mangled in certain regions, esp. across the theta=0 boundary. While subtle here (but MUCH worse in the results I'm trying to visualize), some of the triangles lie outside of the triangulated region. It isn't merely that the polar plot is suffering from poor data coverage; the triangulation is not working properly in polar coordinates and the results are quantitatively different than the rectangular plot. The obvious work-around for this problem illustrates the issue more clearly. If we convert rad, theta back to x, y and do a rectangular plot, the triangulation is much better (not only is there no issue around theta=0, but there are no overlapping triangles), all of the details of the non-polar version are maintained, and the plot looks great. This is not the best solution, as polar plots in Matplotlib are quite elegant. Any help here would be appreciated. It could be that triangulations are just not suited for polar plots; it could be that the theta=0 issue throws things off, etc; I'm just not sure. It would be perfect if I could use the polar axes in the end. Thanks. -dw Daniel, I can't give you much help but I can provide some explanation. If you don't specify a triangulation of your own, the matplotlib tri* functions use lib/matplotlib/delaunay/triangulate as a black box. You are right in saying that it is not suited to polar plots; it assumes cartesian axes. The lib/matplotlib/tri/* functions use triangulations that comprise a number of triangles with vertices ordered in an anticlockwise manner. The delaunay triangulation returns such triangles on a cartesian grid. But if you transform a cartesian triangulation to a polar grid, you invariably end up with some triangles which are ordered clockwise and hence also overlap each other. Tricontour doesn't like this and gives the best results it can given that is has been passed an incorrect triangulation, which from your point of view means the wrong results. In addition, as you have noticed there are other problems around theta=0. In a polar plot points near theta=0 are visible both from the low and high theta ends of the plot, whereas in a cartesian plot they are only visible from one side unless you take steps to repeat such points so the wraparound works. The answer, unfortunately, is to specify your own triangulation using the 'triangles' keyword in your calls to the tri* functions. I suspect that most people who regularly use the tri* functions obtain their triangulations from elsewhere rather than using the matplotlib delaunay code. It should be possible to pass your polar coordinates to delaunay to obtain the triangulation in polar space, then use this triangulation in your tri* polar plots. However, I've tried it (albeit briefly) and it appears to hang the delaunay code. An alternative may be to take a look at griddata (there is an example in matplotlib's pylab_examples directory). It is difficult for me to recommend such an approach, however, as I wrote the tri* functions so that I wouldn't have to use griddata!

lable -- label
Fix that, and it will work.

Re: [Matplotlib-users] AttributeError: 'AxesSubplot' object has no attribute 'set_ylable'
Much appreciated!
It works!

Hi, All
I am trying to add ylable to:
ax1 = plt.subplot2grid((1,3), (0,0), colspan=2)
But got the following error: no 'set_ylable';
Here is my code:
import matplotlib.pyplot as plt
import numpy as np
ax1 = plt.subplot2grid((1,3), (0,0), colspan=2)
ax2 = plt.subplot2grid((1,3), (0,2), colspan=1)
N = 2
Spot = (6.29, 3.47)
Avg = (20.11,18.47)
Ody = (6.39,3.98)
Medium = (6.7,6.12)
ind = np.arange(N)+0.10 # the x locations for the groups
width = 0.15 # the width of the bars
ax1.bar(ind, Spot, width, color='0.35',hatch=\\)
ax1.bar(ind+width, Avg, width, color='0.55',hatch=//)
ax1.bar(ind+2*width, Ody, width, color='0.75',hatch=+)

Re: [Matplotlib-users] Visualizing data for scientists and engineers
It's same problem for which I asked assistance here: http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg22520.html There, Johann provided nifty script with slider, with which help user can shift colormap and get more meaningful image Also speaking about great Basemap package, only shifting colormap can be of no use for different regions, as one region could have elevation from 200m to 3000m for example, while other -2000m to 4000m, making two region images incomparable. This is where set_clim function can help - if we make, let's nice hypsometric colormap from -13000 to 9000m we can use this function to plot region images with same visual information. Some new hypsometric colormaps in Basemap package could find usage On Wed, Nov 16, 2011 at 4:32 AM, Ben Root ben.v.r...@gmail.com wrote: I just came across this paper in my twitter feed.
