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

Hi guys,

I am trying to use the Axes grid toolkit to plot a graph with a second y axes that gives the first y axes in different units (similar to http://matplotlib.sourceforge.net/examples/axes_grid/parasite_simple2.html?highlight=subplothost). I am clearly getting something wrong or missing something as I get both y axes but no graph inbetween. Plot and script attached. Please can anyone see what I have got wrong or point me in the direction of more extensive documentation about parasite axes or SubplotHost?

Many thanks,

Libby
