I don't think is suppose to happen.

FIRST sued in VDEF context is supposed to provide the first non NAN value
for the selected data stream

And yet I'm getting ..

$ rrdtool graph placeholder.png DEF:CPUBusyx=mydata.rrd:CPUBusy:AVERAGE
VDEF:CPUBusyFirst=CPUBusyx,FIRST  "PRINT:CPUBusyFirst:%18.5lf"

Deepest Regards
