Those of you who are PSF mentors for the summer of code, could I ask you to take a look at Edin's resubmitted proposal for enhancing mathtext http://code.google.com/soc/psf/app.html?csaid=edin.salkovic%40gmail.com%3A048a69f9%3A96f5f65b Google will be funding 25 PSF projects, and this one will need a higher score to make the cut. I think the work he is proposing will be a nice enhancement to the mathtext facility which is used by both matplotlib and chaco, and since one of Edin's goals is to refactor mathtext into a standalone project, it should see some usage beyond those two projects. Thanks! JDH
Hello,
I am trying to generate a short movie using matplotlib.
The core of my code looks like
for i in range(1,len(t)):
U0,U1x,U1y,H1 =3D list(sig[i,:])
for x in arange(0,1.001,0.05):
for y in arange(0,1.001,0.05):
xx,yy=3Dtrace(U0,U1x,U1y,H1,x,y)
ts[(x,y)].set_data(xx,yy)
for j in range(0,nobs):
tr[j].center =3D (obs[i,2*j],obs[i,2*j+1])
savefig("f%04d.png"%i)
where the entries of the dictionary 'ts' are lines and the entries of
the dictionary 'tr' a patches (circles). Moving the lines around with
set_data works quite fine, but moving the patches by setting 'center'
does not.
My question: how do I move a patch?
Many thanks,
Jochen

Work around: break up the data into pieces and plot() the pieces rather than the entire data set.

HI,
sorry I just found the way to change the edgecolor of my "bars" by just
changing the global option:
rc('patch', edgecolor='r')
before I use
p1 = bar(......)
cheers

Hi, how would you easily set the EDGEcolor of the bars (using "bar")? I see a "set/get_edgecolor" in the output of the bar command (p1 = bar ...) but I cannot manage to change the edgecolors of my bars... thanks Eric
