Yes, the left hand axis is shrinking in the vertical because it is applying the aspect ratio appropriate for 15 N and the N/S extent of your data. Either make the N/S extent of the map larger; make the left hand column wider; or make the figure shorter. Cheers, Jody > On 25 Apr 2016, at

Re: [Matplotlib-users] subplot layout

Your basemap plot is likely setting the aspect of the axes to "equal", so it resizes the plot accordingly. Otherwise you'd have a pretty nasty amount of vertical distortion. When you save the figure, using bbox_inches='tight' will trim the excess white space from the margins:

Could you try using faulthandler and post the traceback please? That'll help us isolate the problem better. Ben Root On Wed, Feb 24, 2016 at 3:04 PM, Claude Falbriard wrote: > Dear colleagues, > > I've done a build from source of latest *Matplotlib* package and > deployed

[Matplotlib-users] Matplotlib 1.5.1 - Function pcolormesh throws Segmentation Fault

Dear colleagues, I've done a build from source of latest Matplotlib package and deployed it at our IBM z13 machine (s390x). It uses the current release 1.5.1. During the unit tests I found an issue with a test case from NOAA which uses a pcolormesh draw function with basemap. Example 2:

Thanks for your input Fernando. I thought about cross-posting to Jupyter, but I'm glad you also saw it here :) That would help, but not solve all problems. I guess the Figure could hold a tag for referencing, too. It would be nice to get a tag and caption from matplotlib. Maybe Benjamin's

Re: [Matplotlib-users] pyplot.hexbin

Hmm, you are right, there is no way to get back the information that hexbin computed. The hexbin function is massive (in lib/matplotlib/axes/_axes.py) and is a bit tangled up with the artist-handling code, too. I think it would make sense to factor out the hexbinning component into its own

[Matplotlib-users] pyplot.hexbin

Is there a simple way to hexbin using "pyplot.hexbin" and to return the ids of the set of points in each hexbin? That is to output an array of n elements (one for each hexbin), and each element itself an array with the point ids? The sum of the number of inner elements would be equal the sum of

Factor it out and give it to numpy! On Fri, Jan 29, 2016, 17:27 Benjamin Root wrote: > Hmm, you are right, there is no way to get back the information that > hexbin computed. The hexbin function is massive (in > lib/matplotlib/axes/_axes.py) and is a bit tangled up with

Re: [Matplotlib-users] applying an image's colormap to another image

You might have better luck asking the scikit-image people, or the Pillow people. ImageMagick might also have what you are looking for. Cheers! Ben Root On Wed, Jan 27, 2016 at 11:23 PM, Matteo Niccoli wrote: > Can something like this (which by the way I can't get to work):

[Matplotlib-users] Looking for feedback on figures using matplotlib and jupyter notebook

Hi all. This is about a joint jupyter-notebook / matplotlib problem I've been thinking about. So I'm writing a book using jupyter-notebook, and all my figures are generated using matplotlib. In books, there is usually a figure caption with a running number and some description. From what I

[Matplotlib-users] Hide overlapping tick marks in axes corner

Hello, I am looking for a way to hide tick marks (not the labels!) that coincide with axis lines. I think this is a problem for me because of the relative line thicknesses of my axis lines and tick marks, but I want to leave those thicknesses unchanged (I like the look of the thickness settings I

Re: [Matplotlib-users] Looking for feedback on figures using matplotlib and jupyter notebook

In mpl, our figure objects get numbers assigned to them by default, but they can also be strings. These labels are used in the figure window title bar. Perhaps that existing data could be hijacked? Admittedly, most people use the string name to give nice short names to their figures, so maybe
