How to flip the data upside down without flipping the axes?

x = [1 2 3];
y= [6 13 11];
plot(x,y)
set(gca,'Ydir','reverse')

I tried this code but it flips the y axis. I want to keep both axis the same.

Indeed.

One could use

plot(x,-y)

but will, of course put them below the y==0 axis.

Alternatively, there's

plot(x,y)
hold on
plot(x,19-y,'r-*')

There is no picture, only a line like the one provided.

This plot(x,-y) doesn't work plot(x,-y) because it converts the y axis in negative values.

This second option either. I don't want to do any changes to the axis, only flip the data.

Remove the -y from the second; that was a figment of the copy/paste...it's the same idea that Star-S shows.

I am not certain what result you want.

Try this:

x = [1 2 3];
y = [6 13 11];
figure
plot(x,max(y)-y+min(y))

.
