thanks!

it seems it was some missing values that caused a problem for normal but not for kdensity.

In Stata 10, I tried this

the following works fine:
histogram /varname/, kdensity by(yr)

however when I do the same with a normal distribution:
histogram /varname/, normal by(yr)

I get the following error:
error in expression: normden(x,,)*1
