This example shows how to apply a c
Hi Jeff,
I computed the convex hull for the points in paths returned by
Basemap.drawcountries() and I got the attached map (convex hull algorithm:
http://www.scipy.org/Cookbook/Finding_Convex_Hull). You can see the magenta
convex hull polygon with U.S. border lines drawn in black as a reference
Hi,
I'd like to show a background image after plotting dates. I use imshow,
which works, but makes the plotted line erased.
If somebody can help, it would be valuable.
thanks in advance

Here is the code. If the line "ax.imshow(img,alpha=0.5)" is commented out,
the graph is correctly displayed.

Indeed, I was able to extract the necessary pieces from the source
code. In fact I split the function

Dear all,
I am trying to draw a bar graph in which the bars are filled with a striped
pattern rather than a solid color. For example an alternating pattern of red
and yellow stripes with an equal width, at a 45 degree angle with respect to
the bar. Is there some easy way to do this in matplotli

Neal,
I do something similar to this where data that I'm plotting in a 2D line
plot comes from a UDP socket and some memory mapped files. To
accomplish the live updating I have a mix of your #2 and #3. I have a
main GUI thread that displays the plots, then I have a second thread
that gets da
I just put together an animated bargraph to show results from a realtime
process.
I used this as an example:

The tricky part for me was that in the original design, there was a realtime
process running. I have to writ
Dear List,
is it possible to not only assign once color per polygon that is

a properly smooth function. Even if I sample the points closely
enough, in the current approach in almost all of your examples you
always see the underl
