Suppose I have two columns variable "lnexp" and "region" where lnexp is log of expenditure (continuous) and region is a categorivsl variable; 1=Eastern region, 2=Southern region and 3= Northern region. If I want to draw kernel graphs of "lnexp" for these regions on one chart,  what should I do on Stata 10? I need a command.

Your in luck Stata has a command.  Well it actually has many, but the 
one you probably want is...

histogram lnexp, by(region)

..should do the trick.  See -man histogram- (for the main bulk of 
drawing histrograms) and -man twoway_options- (for details of how the 
,by() option works).  There are of course lots of other options for 
labelling your graphs and so forth, all of which are documented in the 
online help (and linked from -man histogram- page).
