I have to update this figure each month and I then have to manually change 1(1)19 to 1(1)20 ond so on.

twoway (bar antal_aabne Tid, barwidth(0.2)) (bar antal_fuldfoerte Tid, barwidth(0.2)) (bar antal_oprettede Tid, barwidth(0.2)) (line liggetid Tid, yaxis(2)), xlabel(1(1)19, labels angle(vertical) valuelabel)

Is it possible to let the number of ticks be equal to the a variable with a constant number? E.g. 1(1)var
Or how can I do this?

Kind regards
Torben
