Reverse the scale of yaxis(1) and yaxis(2)

[Chang Xu]

Hi everyone,

I'm planning to use twoway to draft a plot. We have two Y axis, one is Z-score (ranged from 0 to 3) and one is precision (ranged from 0 to 1.5).

Now I want to reverse the scale of the two Y axis, say, the top of the Y will be 0 and the bottem will be 3 (axis 1) or 1.5 (axis 2). However, I found I can only force the first Y axis with the scale reversed, while I cannot make the 2nd Y axis to be reversed.

Here is my code:

twoway(line Z es, yaxis(1) ysc(rev)clcolor(black black) clpat(dash dash)) (line _seES es, yaxis(2) ysc(rev) clcolor(black black) clpat(dash dash))

Is there any method to reverse the scale of yaxis(2) ?

Thanks
Chang

This may help:

gen _seEs2 = 2 * _seEs  
 twoway  line Z  _seEs2 es, yaxis(1 2) ysc(rev) clcolor(black black) clpat(dash dash) yla(0/3, axis(1)) yla(0 1 "0.5" 2 "1" 3 "1.5", axis(2))
