Re: [Matplotlib-users] Problems with pyplot and cm in Matplotlib ver. 1.4.3
Per request my question is being resubmitted here. I'm attempting to generate contour and a color map in Matplotlib ver. 1.4.3 on a MacBook Pro under Mac OS X ver. 10.10.2 in Python 2.7.3 with the Anaconda environment. A zip file has been attached to this note. Two sub-directories, mathplotlib_1.4.3 and mathplotlib_1.1.1rc are included. mathplotlib_1.4.3 contains the python script that generates the contour and color map plots, jpeg files showing the resultant plots and the input data. mathplotlib_1.1.1rc contains the screen snaps (jpeg files) showing the correct contour and color map plots generated by the same python script and input data under Linux2 using Python 2.7.3 and Matplotlib 1.1.1rc. The questions I have include: 1. What are the differences between Matplotlib vers. 1.1.1rc and 1.4.3? 2. What is going on where? 3. How can I fix this problem?

Re: [Matplotlib-users] Problems with pyplot and cm in Matplotlib ver. 1.4.3
Eric, I took your suggestion and it worked. Thank you. To all the others who responded so quickly, thank you as well. P.S. - I'm still wondering what other differences between vers. 1.1.1rc and 1.4.3 I'll run into. I'll worry about those when I run into them. -- View this message in context: http://matplotlib.1069221.n5.nabble.com/Problems-with-pyplot-and-cm-in-Matplotlib-ver-1-4-3-tp45002p45009.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

The questions I have include:
1. What are the differences between Matplotlib vers. 1.1.1rc and 1.4.3?
Well, you just found one of them. You should be able to find most
substantial changes in http://matplotlib.org/users/whats_new.html.
2. What is going on where?
The plt.axis('scaled') call is freezing the xlim and ylim at values
resulting from a call to nonsingular, which is handling the fact that
when you call axis(), nothing has been plotted and there is no
information about what you want the limits to be. In addition, 'scaled'
is one of the axis options that turns off autoscaling. It has always
been intended to be called *after* plotting with autoscaling on, or
otherwise setting the xlim and ylim to the desired values. I don't know
why it worked for you in 1.1.1rc; I think it was long before this that
it had the behavior of turning off autoscaling, but I haven't checked.
3. How can I fix this problem?
Put the plt.axis('scaled') line after your pcolor or plot line.
As a side note, in general pcolormesh will yield the same result as
pcolor, but *much* faster, so it is recommended in most cases.
Eric

Re: [Matplotlib-users] Problems with pyplot and cm in Matplotlib ver. 1.4.3
Can you re-send this with that error message formatted a bit better (It is
really hard to make any sense of it all squashed into one line like that).
From what I can make it out looks like it is mostly warnings, not errors.
Does it correctly save the figure? Can you show us the two outputs?
v1.1.1 is from Jun, 2012, there are over 5k new commits across 301 files
between the two versions (see
https://github.com/matplotlib/matplotlib/compare/v1.1.1...v1.4.3 but it
chokes and only will show you 250 commits)
Can you put together a minimal working example (which does not rely on any
external files)? That will really help the list pin down exactly what is
wrong and how to fix it.

Hey Starfighter, I want to help, but I also don't like unzipping files from strangers. Can you make a simple script that generates some fake with numoy and the handful of matplotib commands you need to make the figure. -p — Sent from Mailbox On Sat, Feb 21, 2015 at 7:34 PM, Starfighter sdup...@speakeasy.net wrote: Per request my question is being resubmitted here.
