svend, nick thanks for your help.
svend - it works.
nick, thanks for the catplot after trial and error: catplot bar ind_methd if ind_methd != "emerg", over(year) produces svend's suggestion.
i am just wondering though why bargap(-30) did not work i.e. neither:
graph bar (count) x if ind_methd != "emerg" , over(ind_methd)over(year) bargap(-30)
nor
catplot bar ind_methd if ind_methd != "emerg", over(year) bargap(-30)
produces the graph ala [G] p. 125 where the bars slightly overlap each other for the said year. would appreciate further advice/comment.
regards,
bw
