Let's say I have the following data:
500 objects:
-100 are red
-300 are blue
-the rest are green
Is there some python package which can represen the above information
in a pie chart?
Thanks

There are many.
One choice would be Tkinter's Canvas.
def frac(n): return 360. * n / 500
import Tkinter
c = Tkinter.Canvas( width=100, height=100); c.pack()
c.create_arc((2 ,2,98,98), fill="red", start=frac(0), extent = frac(100))
c.create_arc((2 ,2,98,98), fill="blue", start=frac(100) , extent = frac(400))
c.create_arc((2 ,2,98,98), fill="green", start=frac(400) , extent = frac(100))
c.mainloop()

It looks like in python there is more than one way to make a pie
chart. Here's another
from pylab import figure, pie, show
N, red, blue = 500, 100, 300
green = N - (red + blue)
figure(figsize= (6,6))
pie( (red, blue, green),
labels=('red', 'blue', 'green'),
colors=('red', 'blue', 'green'),)
show()
A screenshot of a slightly more elaborate example is at http://matplotlib.sourceforge.net/sc....html#pie_demo

Those python pie chart add ons are not very useful. For my specific pie
chart, I have some 6-8 items to show up and some of them occupy only
2-5% of the pie. This cause the names and percentages to overlap each
other. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hi there,
Are there Excel charting gurus here?? If so then please read on...
Sorry for the cross-post but I'm not familiar with the Excel groups. I've
posted to asp.general because if I have to code a solution to this it'll
probably be done in ASP on a web server, unless there's a significantly
better way.
I'm looking for a way to create over 100 Excel *charts* programmatically.

I'd like to create my own output streams, in order to be able to

could output a string on stderr to start with, and when I have written
a nice GUI, it could be output to a status window or a log file or
something.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
