Thanks. I just saved the actual means I needed and defined a category variable. Used the bar option, and got almost what I wanted.
The remaining problem is how to put all three charts into the same "frame". Can't use the by-option as I see it because this require three equal plots just for different categories.
What I want is to combine the three different plots given here into one box:
. graph bar (mean) X1, over(quart)
. graph bar (mean) X2_a (mean) X2_b, over(quart)
. graph bar (mean) X3_a (mean) X3_b, over(quart)
Is there a simple add-plot option for bar charts that could work?

But also look at -bandplot- from SSC.

What you want aren't histograms in Stata's sense, or in the standard statistical sense either. So, don't look to -histogram- or -twoway histogram- commands for these.
They are all bar charts and -twoway bar- is your best bet at getting them, but each one will need some preparation.

I want to use Stata to make some nice histogram showing some distributional features of my data, but unfortunately I have some problems in finding out how to do it. I've been able to do the following in Excel earlier, but I like the look of the Stata graphics much more, so I hope someone can give me a clue:
Well, I want to use three variable making the histograms.
The first is an indicator of size for my observations (population size in districts), and the two other variable are a dummy variable and a continuous variable describing the districst.
First; I'd like to make a histogram with five boxes. The first box should simply give me the mean of the dummy variable for all district, whereas the four next should give the mean of the dummy variable within each population quartile of the sample.
Second I'd like to add another histogram under the first one where I in the same way show the mean of the continuous variable, only here I'd like to categorize the boxes both by population size and the value of the dummy. Thus, the first two boxes should give the mean value of the continuous variable for all districts with dummy value 0 and value 1. The next two should give the same figures for the districts only in the first population quartile, then the second quartile and so on. I would also be nice if I could add some extra space between the boxes for the total sample, and for the four different quartiles respectively.
