[Matplotlib-users] Trying to reproduce R plot

[Michael K. <mi...@kl...>]

Hello,

I really like Python and Matplotlib, and recommend it to all my colleagues.

I have found this plot:

http://en.wikipedia.org/wiki/File:Operating_system_usage_share.svg

I think it looks good, it is made in R. The code looks clean, not many
settings etc.
I wanted to see if I could make a similar plot in Matplotlib.

So far, this is what I got:

from pylab import *

data = [37.92, 29.72, 13.09, 7.40, 2.80, 2.07]
x = arange(len(data))
ax = subplot(111)
bar(x, data)
xticks( x + 0.5,  ("Windows\nXP", "Windows\n7", "Windows\nVista",
"MacOS X", "iOS", "Linux") )
title("Usage share of web client operating systems: May 2011")
ylabel("Percent Usage")

savefig('barplot.png',format='png')

I have stolen most of the code from an example:
http://matplotlib.sourceforge.net/examples/pylab_examples/custom_ticker1.html

I havent figured out how to color the bars differently, does anybody
know how to do this?


Sincerely
Michael
