[rrd-users] JRobin - how to GPRINT a scalar value?

[Marek VANCO]

Hello,

  I'm using JRobin, and I want to print my value of variable in graph.
How to print my scalar value to graph?

in RRD tool, this is possible with:

 DEF:out={rrd1}:dataOut:AVERAGE 
 VDEF:out90=out,90,PERCENT 
 GPRINT:out90:"Q90 input \\: %8.2lf %s\\n" 

in JRobin API, I didn't find how to do it...

Thanks you very much for any ideas!
