multiple labels - ggraph gpl summary

[mitja decman]

Hi!

 

I tried to add multiple labels to my stacked bar using concatenate, "$",
"+" but nothing works.

So how do I add more labels to graph using GPL. My label in the ELEMENT:
part looks like this:

label(summary.percent( COUNT,base.coordinate(dim(1)) ) )

 

I tried:

label(COUNT, summary.percent( COUNT,base.coordinate(dim(1)) ) )

and:

label(concatenate (COUNT, summary.percent( COUNT,base.coordinate(dim(1))
) ))

 

But nothing works...

 

Thanks
