graph constant variables

[Allan Andreotti]

Hi, for example i have 3 variables with constans and i want to graph a line that follows each constant (like in the image).
Thank you very much.

X1	X2	X3
5	10	15
5	10	15
5	10	15
5	10	15

You need a different data layout to do this, as advised in response to your cross-posting at https://www.reddit.com/r/stata/comments/guzbhg/graph_constant_variables/

* Example generated by -dataex-. To install: ssc install dataex
clear
input byte(x1 x2 x3)
5 10 15
5 10 15
5 10 15
5 10 15
end

preserve
gen id = _n
reshape long x, i(id) j(order)
twoway connected x order , xla(1 2 3)
restore

A "constant variable" may be a difficult case indeed.

Not sure about the use of the graph, but perhaps just an alternative:

graph bar x*
