Hi Maike,
I found that the use of pylab allows a lot more control over your
plots. Example:
import pylab
x1 = srange(0,1.1,0.01)
d1 = [2*x+x^2 for x in x1]
d2 = [3*x+0.9*x^2 for x in x1]
title='Test plot'
pylab.clf() # clear the figure first
pylab.figure(1)
# plot some data and add a legend
pylab.plot(x1,d1, label="d1")
pylab.plot(x1,d2,label="d2")
pylab.axvline(x=0.5,ls='-.')
pylab.legend(loc=0) # print the legend
pylab.title(title)
pylab.ylabel("$f(x)$") # label the axes
pylab.xlabel("$x$")
pylab.savefig('foo.png') # fire!
I have not found out how to make the adjustments you asked for, but
there is some helpful literature around that explains how to use pylab
in detail (look for matplotlib on the web). I heard that the plot
functionality in sage is being worked on but I don't know how far it
is at the moment. Perhaps it is possible to do all this already. I do
know that you can set the axes ranges for both the x- and y-axes quite
easily:
P=fun.plot(x,0,1)
P.axes_range(xmin1,xmax1,ymin1,ymax1)
P.axes_labels(['$A_v$', '$B_v$'])
P
Where fun is the function to plot, x is the variable on the x-axis,
and P.axes_range defines the ranges of the axes.
Hope this helps until someone more knowledgeable helps out.
Stan
