A bihistogram -- I didn't know before searching -- is a dual histogram
with one group's frequencies shown as negative.
Rajesh found nothing, but -search histogram- points to this:

tip illustrating the use of twoway__histogram_gen for
creation of complex histograms and other graphs or tables
The text is accessible to all via

That includes a worked example.
Here is another:
sysuse auto, clear
twoway__histogram_gen mpg if foreign, width(2) start(10) freq ///
gen(freq_foreign mpg_foreign)
twoway__histogram_gen mpg if !foreign, width(2) start(10) freq ///
gen(freq_domestic mpg_domestic)
replace freq_foreign = -freq_foreign
twoway bar freq_foreign mpg_foreign, barw(2) || ///
bar freq_domestic mpg_domestic, barw(2) ///
legend(order(1 "Foreign" 2 "Domestic"))

Is it possible to produce a bihistogram in stata? Nothing turns up on
findit
or search. I was trying to write a program to do that. But can one get
stata
to produce histogram with -ve frequencies?
