Mirror about Y axis

How can I plot this axis to the mirror about the y axis and x axis pointing the opposite direction? Thank you.

a = [1 2 3 4 5 6 7 8 9 10 11 12 13 14];

b = [1 2 3 4 5 6 7 8 9 10 11 12 13 14];

plot (a, b,'.')

Something like this:

a = [1 2 3 4 5 6 7 8 9 10 11 12 13 14];
b = [1 2 3 4 5 6 7 8 9 10 11 12 13 14];

plot(a,b);

hax = gca;
hax.XDir = 'reverse'; % flip axis direction
hax.YAxisLocation = 'right'; % move ticks & labels to the other side
