Hi All,
I would like to have these 2 plot aligned with each other. Plotyy give 2 line instead of 1 line.
a is temp, b is altitude, c is pressure.
Code
%%%b is derived using atmospalt(c)
figure(1)

yyaxis left
ax1(1) = plot(a,b);
yyaxis right
ax2(2) = plot(a,c);
%%%%%
C variable should be placed reversely in secondary y axes. Output shoud looks like the image attached (i.e. just as example).
Cheers

You can use the following command to reverse the order of the elements in the variable c:
c = flip (c);
