Re: [Matplotlib-users] Missing something with parasite axes (AxesGrid toolkit)

[Elizabeth Harper-C. <h-...@ci...>]

Hello,

I've been playing with the script and I now know a little bit more about
what is wrong. I can get the full graph space to plot by changing:

ax_mass = SubplotHost(fig, 1,1,1, aspect=1.)
to
ax_mass = SubplotHost(fig, 1,1,1)

but then a line is never drawn. I have removed the x and y axis limits and
it plots the axes for the limits of the date but no line for the graph? Here
is the relevant part of the code:

fig = plt.figure()
ax_mass = SubplotHost(fig, 1,1,1)

frac_to_mass = gasmass
print 'frac_to_mass', frac_to_mass
aux_trans = mtransforms.Affine2D().scale(1., frac_to_mass)
ax_frac = ax_mass.twin(aux_trans)
ax_frac.set_viewlim_mode("transform")

fig.add_subplot(ax_mass)
ax_mass.plot(time,massesMsun, linestyle='-', color='k', linewidth=2.0)

ax_mass.axis["bottom"].set_label("Time (Myrs)" )
ax_frac.axis["right"].set_label("Fraction of Original Gas Mass in Stars" )
ax_mass.axis["left"].set_label("Mass in Stars (Msun)" )
ax_frac.axis["right"].major_ticklabels.set_visible(True)
ax_frac.axis["top"].major_ticklabels.set_visible(False)
plt.savefig(frame_template %(folder,name[0],name[int(sys.argv[1])-1]),
format="eps")


can I not use ax_mass.plot?

Thanks,

Libby
