True, but I find it strange that references to r() work with -kdensity- (or commands like -summarize-), but hot with -histogram- (nor with -graph box-) where `r()' seems to be required.

You do get the correct graph with:

*************
clear
cap graph drop _all
set obs 1000
g x=exp(rnormal())
su x, de
hist x if x<`r(p95)', name(ha)
*************

of course, all the "hist" below should be "kdensity", and the correct piece of code is

/**********************/
clear
cap graph drop _all
set obs 1000
g x=exp(rnormal())
su x, de
local p95=r(p95)
di r(p95)
kdensity x if x<r(p95), name(ka)
kdensity x if x<`p95', name(kb)
kdensity x, name(kc)
/************************/

Now, I have not tried all types of graphs, but -kdensity- seems to behave as expected:

/**********************/
clear
cap graph drop _all
set obs 1000
g x=exp(rnormal())
su x, de
local p95=r(p95)
di r(p95)
hist x if x<r(p95), name(ka)
hist x if x<`p95', name(kb)
hist x, name(kc)
/************************/



Best,
