[rrd-users] backfilling data with 2 DS

[Mag Gam]

I have several csv files from months ago and I would like to put them
into rrd so I can graph the data.

The format of the file is:
run.csv
epoch:int

wait.csv
epoch:int

There are about 2k entries in each file

My question is, are there any example of 2 data sources and filling up
old historical data? I seen the Kilometers example,
http://oss.oetiker.ch/rrdtool/tut/rrdtutorial.en.html, but thats only
with 1 datasource. 2 datasource example would be much appreciated.

TIA
