making publication quality plots

Hi Chaitanya (and everyone else),

thanks for some nice advice! The font and legend frame tips worked quite well.

I would appreciate it if it was possible to remove the legend frame by default, i.e. in the matplotlibrc file, if possible. In my opinion, this frame clutters the plot unnecessarily; I rarely see such frames in publications.

Thanks!
Paul.

Hi Paul,

Can you try
font.size: 10
legend.fontsize: small [or medium] in your rc file.

Defining the fontsize and then defining the fontsize of the xtick
labels, legend etc with respect to this font size seems to work better
than defining everything by hand.

Switching off the legend frame does seem to save some place. You can
use pylab.legend('your legend').draw_frame(False)

Cheers,
Chaitanya

Hello again,

I can set the figure size and font size, that all works fine.
However,
the legend is prohibitively large: for a plot 3 inches wide (why
doesn't matplotlib use centimeters or similar?), the legend takes up
about one third of the plot. This does not look too good...

Please post a complete example. As for inches vs cm, that is my fault
-- I can't remember if it was for matlab compatibility, or due to my
provincial ways this side of the pond.

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.

I frequently make the frame semi-transparent, though this won't work for EPS

  leg = ax.legend(...)
  lege.get_frame().set_alpha(0.5)

Some rc default for the legend frame (on/off, alpha) would be useful.
