Re: [Matplotlib-users] boxplot behaviour in an extreme scenario

Even though I'm familiar with the boxplot source code, I largely use IPython for quick investigations like this. In IPython, doing something like "matplotlib.Axes.boxplot??" shows the full source code for that functions\. Then I saw/remembered that boxplot now just calls matplotlib.cbook.boxplot_

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: fig.savefig('map_and_

Chad, My recollections is that matplotlib doesn't distribute the source code to FreeType, it only uses it as a dependency. As such, MPL is in the clear with its more permissive licensing. -Paul On Fri, Feb 17, 2017 at 12:45 PM, CAB wrote: > Hi, All, > > I just went to install matplotlib version

[Matplotlib-users] Setting boxplot confidence intervals manually

Hey folks, I'm working on a patch to axes.boxplot that will allow the user to manually specify the median and confidence intervals (notches) on a boxplot. My need for this arises since I compute the notch locations using the BCa-method, which depends on Scipy. My question relates to how to best h

Re: [Matplotlib-users] use shapefile to create a mask?

To the best of my knowledge, this beyond the scope of matplotlib. Scipy or Shapely *might* have something for you, but you best bet is to look into the raster clipping functionality of GDAL/OGR. Hope that helps, -paul On Thu, Nov 3, 2011 at 3:40 PM, questions anon wrote: > Hi All, > Is there a w

I always taylor a matplotlibrc file for a given project, but you can modify the rc parameters on the fly: http://matplotlib.sourceforge.net/users/customizing.html#dynamic-rc-settings You need to set themodified rc parameters at the top of your script. Hope that helps. -paul On Wed, Jan 25, 2012

There is undoubtedly a more efficient way to do this, but give this a shot: import numpy as np import matplotlib.pyplot as plt x = np.arange(0, 10.5, 0.5) y = -3.0*x + 0.5*x**2 color_list = ['FireBrick', 'Orange', 'DarkGreen', 'DarkBlue', 'Indigo'] limits = np.arange(0, 11, 2) fig, ax1 = plt.sub

Re: [Matplotlib-users] open ascii grid data and plot

In my GIS experience, rasters don't have prj files. That's something that seems to be pretty specific to ESRI shapefiles. Point is, I don't think that's going to help you. All of the basemap examples use netcdf files. I think your path of least resistance right now is to figure out how to convert
