One of the first rules of troubleshooting, and the more scientific method
type approach is to reduce your variables.

First, have a small script returning values for one data point. Set up this
one datapoint using ncv, and one graph for that datapoint. Get it to work.
Once it does, add another and another until you break it. Compare what was
working and what's not working, and you'll find your issue.

All things considered, it's a waste of time to troubleshooting the overly
complex problem by bruteforcing it, when you could easily setup an process
with control variables and experimental variables.

Last time I had this problem I did 2 tings:

1) was to change

NCV_inqGraph="DIHM11a:GAUGE,DRE11a:GAUGE,MIRR11b:GAUGE"

to

NCV_inqGraph="*:GAUGE"

2) was to put


TEST2RRD="......,inqGraph=ncv"

not as the last item

TEST2RRD="......,inqGraph=ncv,files"

or something like this.

Don't know which was the tricker to make the graph happen, but it did.
