If there are one or more narrow wedges on a pie graph, narrow enough that
the percentage values overlap and are hard to read, there seems to be a
knife-thin missing wedge from the pie, including a break in the
circumference.
Is this configurable, even if it means that the border completely covers the
colored interior of ultra-thin wedges?

How can I customize a pie graph autopct format string to display the value
for one of the regions to a specified precision? If I have category A
presenting 5ドル.25, category B representing 1ドル.30, and category C representing
2ドル.00, how do I get the numeric value (not the label) displayed for category
A to be "5ドル.25" instead of "NN.N%"?

You will have to extract the x and y values, and convert them from
strings to values matplotlib can understand (for example dates and
floating point numbers). Eg
In [30]: d = {'00:00:00':'23', '00:01:00':'29', '00:02:00':'13',
'00:03:00':'78',
'00:04:00':'45', '23:59:00':54}
In [32]: from dateutil.parser import parse
In [33]: items = [(parse(date), float(val)) for date, val in d.items()]
In [34]: items.sort()
In [35]: items
Out[35]:
[(datetime.datetime(2008, 7, 30, 0, 0), 23.0),
 (datetime.datetime(2008, 7, 30, 0, 1), 29.0),
 (datetime.datetime(2008, 7, 30, 0, 2), 13.0),
 (datetime.datetime(2008, 7, 30, 0, 3), 78.0),
 (datetime.datetime(2008, 7, 30, 0, 4), 45.0),
 (datetime.datetime(2008, 7, 30, 23, 59), 54.0)]
In [36]: dates, values = zip(*items)
In [37]: plot(dates, values)
Out[37]: [<matplotlib.lines.Line2D object at 0xb45a5ec>]

Hi,
Wondering if anyone has done something similar and could point me in the
right direction.
I have a dictionary like this:
Dict{'00:00:00':'23', '00:01:00':'29', '00:02:00':'13', '00:03:00':'78',
'00:04:00':'45', >....> '23:59:00':54}
So as you can see there is 24 hours worth of minutes, with a value attached
to each minute.
Firstly, just to note the Dictionary "Dict" is not actually in order as
above, it is all jumbled up.
However is it possible to plot a dictionary using MatPlotLib, and using the
time along the x-axis and values up the y?
Thank you in advanced

Ho you got the point...
self.clutter_low.GetPosition() didn't returned an int...
self.clutter_low.GetValue return an int an it works now.
I missed this because I thought that 
self.norm = plt.Normalize(vmin=self.low_clutter_val,
vmax=self.high_clutter_val)
would have crashed before in this case, but seems it does not do any
computation on Normalize call.
Anyhow, thank you a lot, sorry to have send this error, I could have read my
code deeper first.
Regards,
Lauent

Maybe this is what you need:
self.ax.set_xlim(xmin, xmax)
?

I am using matplotlib to draw and show my plot, now I want to know how may I
add manual axes scale to it.
I need to manually show the axes scale (from min to max value that I have)
the below is some part of my code.
.
.
.
from matplotlib.figure import Figure
self.fig = Figure( figsize =5, 4 ))
yLine = self.ax.plot( xData, yData, 'ro-', linewidth = 2 )
fitLine = self.ax.plot( xData, fitData,'bo-', linewidth = 1 )
self.ax.set_xlabel('X')
self.ax.set_ylabel('Y )

Charlie was kind enough to build a windows installer for the release
candidate for testing, which is available here
 http://matplotlib.sourceforge.net/tmp/matplotlib-0.98.3rc2.win32-py2.5.exe
We aren't going to wait around for too long, so if you are able to
test, please do so sooner rather than later. In the absence of
serious problems, we'll be pushing out a release in the next day or
two.

I would like to see what
 self.low_clutter_val = self.clutter_low.GetPosition()
 self.high_clutter_val = self.clutter_high.GetPosition()
low and high clutter val are (can you print them, as well as their type, eg
 print low', type(self.low_clutter_val), self.low_clutter_val
and likewise for the high val. From the error, it looks lik they are
not scalars.
