Hi,
This is my function which does the plotting. The "coeffarr" is a 2D
array (function uses 7 first columns) with first column being
frequencies, other columns being real/imag part of whatever I'm
plotting.
#################
import matplotlib
matplotlib.use('ps')
import pylab
def plot(coeffarr):
'Do the actual plotting.'
nfreqs, ncoeffs = coeffarr.shape
legends = []
for i in range(1, 6, 2): # real part columns
pylab.plot(coeffarr[:,0], coeffarr[:,i], RE_STYLE)
legends.append('l = %i' % int((i + 1) / 2))
pylab.plot(coeffarr[:,0], coeffarr[:,i+1], IM_STYLE)
legends.append('l = %i' % int((i + 1) / 2))
pylab.legend(legends)
pylab.xlabel('Frequency [eV]')
pylab.ylabel('$A_{lm}R^{-l-1}$')
pylab.savefig(PLOTFILE)
####################
My matplotlibrc file is essentially this:
####################
backend : MacOSX # added by paulanto on 16. feb. 08
numerix : numpy # numpy, Numeric or numarray
lines.linewidth : 1.0 # line width in points
font.family : serif
font.size : 10.0
text.usetex : True
axes.linewidth : 1.0 # edge linewidth
legend.fontsize : 10.0
figure.figsize : 3.0, 2.3 # figure size in inches
####################
Is this complete enough? If you do the plot, you'll see that the plot
is about one column wide (7 cm-ish) and that the legend is relatively
large. I made similar size plots in Gnuplot before, at font size 10,
but the legend was somehow less dominant.
Also, will it help getting rid of the rectangle?
cheers,
Paul.
