Matlab second y-axis label does not have the same "padding" as the first

I made a plot and wanted to add a second y-axis with different units of measurement.

Here is what I did:

...
...

plot(x,y,x,y1,x,y2)
ax1=gca;
set(gca,'YTickLabel',num2str(get(gca,'YTick').'))
legend('0.5 atm','1  atm','2  atm','Location','best')
title('H_2S equilibrium partial pressure for different total pressures')
xlabel('Temperature (K)')
ylabel('Partial pressure (Pa)')
hold on
ax2 = axes('Position',ax1.Position,...
    'YAxisLocation','right',...
    'Color','none');
ax2.YLim = [0 0.25];
ax2.XTick = [];
ylabel(ax2,'Partial pressure (atm)') % label right y-axis

Here is the result: enter image description here

How do I get the right label to have the same padding between itself and the edge of the figure as the left label and border?

Solution

  • I've just discovered export_fig.

    It automatically crops extra space from plots and also adds nifty features, such as anti-aliasing!
