Restrict range of y axis

[paulvonhippel]

I am plotting data whose y values range from -14.9 to +14.9. Yet the range of the y axis is (-20 20), even when I try to restrict it to (-15 15). Why? How can I restrict it to (-15 15)?

clear
set obs 21
gen i = _n
gen est = _n - 11
gen upper = est + 4.9
gen lower = est - 4.9

twoway rcap upper lower i || scatter est i, yscale(range(-15 15))

The default ticks will also extend the y-axis as needed. You will need to customize the tick labels to help with restriction.

twoway rcap upper lower i || scatter est i, yscale(range(-15 15)) yla(-15 15)
