Plots with multiple of one axis only parse the text for the last axis created

[jamescamdenmartin]

Plots with multiple of one axis, for example a seperate x axis on both top and bottom of the figure, only parse the text for the last axis created.

MATLAB changes the xaxis or yaxis child to be an array of NumericRuler objects. Fixing this isn't completely straightforward, as the naming scheme for the NumericRuler properties is different. Also there appears to be no way to get the 'Location' property of the NumericRuler, so MATLAB only makes this accessible for the last axis to be created.

Example with two y axes. Only the one on the right is parsed, as it was created last.
``
x=1:0.1:100;
y=sin(x);
y2=sin(x)-1;
fig = figure;
yyaxis left
plot(x,y)
title('$F_z$');
text(pi,0,'$\leftarrow \sin{x} \frac{abc}{de_f}$')
xlabel('yabdxd $F_x\cdot\ y\cdot\phi$')
ylabel('$\varphi$')

ylim([-2 2])

yyaxis right
plot(x,y2)
ylabel('$\varphi_2$')
l = legend({'abcyasdfasdfadsfadsfasdfa','$F_x$'});
