Re: st: graph bar - how to add 'external' label above stacked bar chart

[Phil Clayton <philclayton@internode.on.net>]

I'm sure others have better suggestions but 2 options include: 
 
1. use -twoway bar- instead of -graph bar-, and scatter C against the group with 
invisible markers labelled with their value 
 
2. draw the bar graph without the labels, then invoke the Graph Editor to add the 
labels manually (requires more programming): 
 
_gm_edit .graphname.plotregion1.barlabels[1].text.Arrpush C1 % 
_gm_edit .graphname.plotregion1.barlabels[2].text.Arrpush C2 % 
... 
graph display graphname
