[Matplotlib-users] How to set axis limits with text objects ?
Hi,
I'm trying to draw a bar chart according to
http://matplotlib.sourceforge.net/examples/api/barchart_demo.html, and I'm
having to difficulties :
- when the first bar has a zero height, it is no taken into account during
the axis limits calculation and is not visible
- texts objects can exceed chart area and collide with the chart title.
Is there a way to calculate the axis limit to use to include all texts
objects into the chart area ?
Here is the code I used :
[code]
#!/usr/bin/env python
import numpy as np
import matplotlib.pyplot as plt
menMeans = [0., 998., 1210., 1449. ,
1496., 1493., 1593.40002441, 1517.5 ]
ind = np.arange(len(menMeans)) # the x locations for the groups
width = 0.8# the width of the bars
fig = plt.figure()
ax = fig.add_subplot(111)
rects1 = ax.bar(ind, menMeans, width, color='r')
# add some
ax.set_ylabel('Scores')
ax.set_title('A very very long title for testing.')
def autolabel(rects):
# attach some text labels
for rect in rects:
height = rect.get_height()
ax.text(rect.get_x()+rect.get_width()/2., 1.05*height,
'%d'%int(height),
ha='center', va='bottom')
autolabel(rects1)
plt.show()
[/code]
Best regards,

[Matplotlib-users] Need help with a local install of matplotlib under Linux
Hi, I would like to make a local install of matplotlib under Linux, but I've got 2 problems : 1) I didn't find how to setup the build to use the PGI C compiler. I tried python setup buil --help-compiler but there seems to be no preconfigured options for this compiler, and the default doesn't work (see log2, below) How should I configure this ? 2) I have a problem with the configuration of gtk dependencies. Theses dependencies are also locally installed and the setup.py script didn't find them (see log1 below) But, the strange thing is that, if I modify the setup.py script and add "import gtk" on the top of it, the configuration seems to run nicely (see log2). Indded, it seems that "import gtk" works in setup.py but doesn't in setupext.py, which is very weird to me Have you got any ideas on how to solve this ?

[Matplotlib-users] how to customize informations given by the navigation toolbar ?
Hi, I'm using the twiny fonction to plot two functions on the same axes. I would like to have both informations displayed on the navigation bar. Now, I have : pan/zoom : x=220, y=80 Is-it possible to customize the toolbar in order to have pan/zoom : x1=220, x2=300, y=80 -- LB -- Come build with us!

[Matplotlib-users] Missing files on the web documentation
Hi, The documentation presented on http://matplotlib.sourceforge.net/examples is a very good source of information but on some pages it doesn't give all the data needed to have the example running. Indeed, some example needs external files and they are not given in the web documentation, for example : http://matplotlib.sourceforge.net/examples/user_interfaces/mpl_with_glade.html needs "mpl_with_glade.glade" http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_wx3.html needs "../data/embedding_in_wx3.xrc" I thing there should be some links on the web pages to download theses files. At least, it should be said in the docstring where to find them, don't you think ? -- LB -- ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
