Graph combine, align x axis

[Diego Marino]

Hi, I have 3 histograms coming from different databases. I am using graph combine to combine them into one graph as in the picture. I would like to have the x axis aligned. I thought the problem was for not having the title in the first and third histograms. So I added an X to check but it seems that the problem also comes from the labels in the y axis.

Is there an easy way to align them?

This is my code:

graph combine "Writing\hist_obs_tohigh.gph" "Writing\hist_obs_placebo.gph" "Writing\hist_obs_tolow.gph", cols(1) xcommon

Thank you

This is an old problem with no easy solution. See https://www.statalist.org/forums/for...-graph-combine

Could you increase the scale of your Y axis in the first and third plots to 1000 (and make sure it includes the comma in the format). I know that's not ideal, as it changes the scale quite a bit, but, I think that might fix your problem here. It's hard to say without sample code, but it would look something like this:

hist var1, ylab(0(1000)1000, angle(horizontal) format(%9.0gc)) ysc(range(0 1000)) freq name(hist1, replace)
hist var2, ylab(,angle(horizontal) format(%9.0gc)) freq name(hist2, replace)
hist var3, ylab(0(1000)1000, angle(horizontal) format(%9.0gc)) ysc(range(0 1000)) freq name(hist3, replace)

gr combine hist1 hist2 hist3, cols(1) xcommon

Thank you all! I ended up changing the angle of the labels, so that I keep the same style format of other graphs in the paper.
