Two way area - lines get "thin" as they move up

[Joao Pugliese]

Example code:

set obs 200
gen indicator = uniform()<=0.5
gen y = _n
twoway (area indicator y)

As you can see, the lines get "thin" as they move up on the y-axis. Is there any way to change that?

I think you can use another kind of graph like "spike". This is my example. I am not sure whether it is what you need.

set obs 200
gen indicator = uniform()<=0.5
gen y = _n
twoway (spike indicator y, lwidth(thick))

#1 is inevitable. You are plotting trapezia in general, so the sides are sloping,
