Hi all,

Using the Bar Chart, I can use sample weights and graph the mean of
each of my variables to get the plot of interest.  I was wondering if
I could get a line graph showing same data (ie, lines instead of
bars).  Using Stata 10.1, it seems that there is no way to enter in
sample weights for a basic twoway line graph, unless I'm over looking
something.

My current bar chart syntax is:
graph bar (mean) drugA (mean) drugB (mean) drugC [pweight = pwt], over(year)

And the bar chart is spot on, like it should be, however I'm dumb
founded of how to coerce stata into giving me the same graph only with
lines.  Thanks to previous help from this listserv, I know that I can
collapse the data to get Stata to get a line graph of means, however
I'm unsure of how that can be done while maintaining the weighting
procedure and hence I'm a tad apprehensive to do that.  If I could
just swap the bars I'd be happy.  Any thoughts?  Thanks,

Mike
