Thanks for the plug. -stripplot- is on SSC. 

For comparison of two distributions I would add -qqplot- and -kdensity-.

Looking at this, I am still not sure that this is the best way of  
displaying the data. For several reasons

1. Histogram shape is notoriously sensitive to the width and starting  
position of bins.
2. The eye is better at comparing side-by-side plots where position on  
the same scale is used to make the comparision
3. A histogram does not show the data
4. A histogram cannot be used to infer descriptive statistics

I would recommend, as an alternative, Nick Cox's -stripplot- with - 
vertical- and -box- options. Suddenly you see far more of the data,  
and are in a far better position to make comparisons.
