I fought some time with NumPy, SciPy, and Matplotlib under the same configuration -- in the end I settled for re-installing Python via homebrew. Everything worked like a charme out of the box.

Any ideas? Also, as in the example http://matplotlib.sourceforge.net/examples/pylab_examples/multiple_yaxis_with_spines.html here , the legend seems to be behind the quantity being plotted against the one of the secondary y-axis....does this have anything to do with that?...it is that maybe the legend is draggable but I am not getting to it? gsal -- View this message in context: http://old.nabble.com/legend-not-draggable-when-secondary-y-axis-present-tp33162008p33162008.html Sent from the matplotlib - users mailing list archive at Nabble.com. |

Trying to place a colorbar in a figure. The code below, placed in a file and executed with python, draws 4 maps using basemap. I've been unable to get a colorbar to show up anywhere on the figure. Ideally I would like the option of placing a colorbar across the bottom, spanning across both bottom map panels. Also would need the option of placing a colorbar either to the right of or below each map. Uncommenting the two lines under "Here make a colorbar" cause an error.

For several of the graphic on that page, dropping the code into a file and running also produces various errors.

We will have to get that fixed on the website (not sure why it is happening). I have attached an example file for you to try. Also, which version of matplotlib are you running? Without the error message you are getting, it would be hard to tell you what is wrong (most likely it is a version issue). Ben Root Version 0.99.1.1 installed through Synaptic package manager on system running Ubuntu 10.04. I'd rather not attempt a fresh install from sources just yet. Adding a colorbar alonside each map panel is possible. Anyone able to modify that code to make that work? I'm assuming it very simple for an experienced user. Also, is it possible to add axes_grid1.py to my directory? If I want to get fancy in the future I will install version 1 and use axes_grid1.py.

Hi Per, I think you want to use the 'ticklabel_format' method: http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.ticklabel_format Here's your example modified some. 'some_point2A.pdf' produces exactly the same as the default. 'some_point2B.pdf' does not use an offset, and maybe produces more of what you were looking for. import pylab as pl some_points = [0.94589396231920286, 0.94593953605915637, 0.94601787712257401, 0.94597530431819743, 0.9459922123931529, 0.94622433138703055] pl.plot(some_points, '.-') pl.ticklabel_format(style='plain',useOffset=0.9458,axis='y') pl.savefig('some_point2A.pdf') pl.ticklabel_format(style='plain',useOffset=False,axis='y') pl.savefig('some_point2B.pdf') -Yann On Wed, Jan 18, 2012 at 4:15 AM, Per Nielsen <ev...@gm...> wrote: > Hi all > > I get a rather strange scaling / choice of y-axis ticks for the following > script: > > import pylab as pl > > some_points = [0.94589396231920286, 0.94593953605915637, > 0.94601787712257401, 0.94597530431819743, 0.9459922123931529, > 0.94622433138703055] > pl.plot(some_points, '.-') > pl.savefig('some_point2.pdf') > > output here: > > http://dl.dropbox.com/u/2244215/some_point2.pdf > > This is a rather simple plot, but matplotlib choses a strange scaling of > the y-axis by default.

Hi all
I get a rather strange scaling / choice of y-axis ticks for the following
script:
import pylab as pl
some_points = [0.94589396231920286, 0.94593953605915637,
0.94601787712257401, 0.94597530431819743, 0.9459922123931529,
0.94622433138703055]
pl.plot(some_points, '.-')
pl.savefig('some_point2.pdf')
output here:
http://dl.dropbox.com/u/2244215/some_point2.pdf
This is a rather simple plot, but matplotlib choses a strange scaling of
the y-axis by default. How do I get a more standard scaling without
specifying the yticks manually?
Best
Per

Problem: Installation of matlibplot for Python 2.7's .exe file requires that Numby be installed first. But the Numby installation list does not include a version for Python 2.7. The highest available version is for Python 2.6. So, Numby 2.6 won't install because it can't find a Python 2.6 and matlibplot for Python 2.7 won't run because it can't find an installed Numby. Is there a work around? |
