In your first email you said you were using latex, but you were actually us=
ing=20
mathtext. I can confirm the problem when I disable usetex and instead use=20
mathtext. Mike, is this something easy to fix?
Darren

Oups I found the problem, I don't know why because it was working fine befo=
re=20
the upgrade to gutsy but I have to change matplotlib configuration and=20
everything is working fine if I put in the file:
rc('text', usetex=3DTrue)
sorry to have bother you with this,

I don't think the problem is in dvipng because I have exactly the same when=
=20
I'm using GtkAgg and before your message I didn't have dvipng installed. I'=
m=20
using ubuntu gutsy so perhaps there are a change in the lib.

I don't think its a problem with matplotlib; I can't reproduce the problem on 
my machine. Maybe its an issue with your dvipng? I'm using version 1.9.

Hey, Ive got 10 strings of data that i plot into 1 big window, but somehow
matplotlib gives me a very strange set-up. I am rather new to matplotlib and
python so im kinda stuck now!
heres an image of what i get and part of my code:

def residuals(p, y, x):
 A,k,theta,C = p
 err = y - (A*sin(k*x+theta)**2+C)
 return err
def peval(x,p):
 A,k,theta,C = p
 return A*sin(k*x+theta)**2+C
for i in range(len(data)):
 dat = data[i,:]
 x=arange(1,17,1)
 y_meas = dat[2:]
 freq1=dat[0]
 freq2=dat[1]

 pylab.subplot(subnr)
 pylab.plot(xfine,peval(xfine,plsq[0]), 'r')
 pylab.errorbar(x,y_meas,yerr=sqrt(y_meas),fmt='bo')
 pylab.xlabel('Number [...]')
 pylab.ylabel('Value [...]')
 pylab.grid(True)
pylab.legend(('Fitting', 'Measured Data'),
 'upper right', shadow=True)
pylab.title('Least square fit for Mira')
pylab.show()

I just want the graph to be arranged properly into the window.
Later i need to add a main title, a title for each graph and return the
values that the computer used to fit the graph (meaning A, k, theta and C)
Thanks a lot!

What is argument to do that? In API I didn't find this.

If if decrase the width, my pie isn't rounding but eliptical.

In the examples subdirectory of the mpl distribution, see contour_image.py.

Hi,
when I plot 2D data with imshow() and then add a contour plot, my
contours have an offset in relation to the data. At the same time there
is white space at the edge of my plot, so I assume that it is the
imshow plot that actually gets shifted. I'm new to Python and
matplotlib, so I don't really understand that. Can anybody give me a
hint about how to get rid of this offset?
Cheers,
Christian
