Friedrich Huebler <huebler@rocketmail.com> notes that when draws a bar graph
an specifies the option and suboption -yvaroptions(relabel(...))- that 
-graph bar- ignores his weights,

This is a bug.  -graph bar- is currently ignoring any specified weights if
suboptions -relabel()-, -total-, or -sort- are specified within the options
-over()- or -yvaroptions()-.  The bug has been fixed and will be available in
an ado update either later today or tomorrow.

If Friedrich has an immediate need for a graph with weighted data, he can get
the correct bar heights by using -collapse- with -aweight-s and then use
-graph bar- with the -asis- option to graph to bars.
