Hallo all, 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:

xfine=arange(min,max,step)
subnr=250+i+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!
