Hello,
In the following code:
a = [180 170 150 90 45 5 0 -5 -30 -70 -100 -125 -150 -175];
b = [1 2 3 4 5 6 7 8 9 10 11 12 13 14];
plot (a, b,'.')
How i can plot the b variable (as the y-axis) with the high numbers down and the low numbers up in the plot?
Thanks

After your plot call, add this line:
set(gca, 'YDir','reverse')
See the documentation for Axes Properties for details.

If you planning to change the ylabel use
set(gca,'YtickLabel',14:-2:0)
Or else, if you wants to flip b alone you can use
fliplr(b)
