Re: st: how to draw a timeline bar failure figure.

[Nick Cox <njcoxstata@gmail.com>]

Good clear question. Consider

 gen id = _n

 labmask id, values(machine_id)

 twoway rbar  fail_b fail_e id, horizontal barw(0.2) yla(1/5, ang(h)
val)  || ///
scatter id  fail_e, ms(none) mla(fail_r) mlabpos(12) mlabgap(*4) legend(off)

where -labmask- is from SJ, i.e. -search labmask- will show
