Hi,
I have tested the example in ns-3-dev/examples/stats with latest ns3-
dev, simulation works fine, but the plot is not produced.
Probably the reason is that the query
select exp.input,avg(100-((rx.value*100)/tx.value)) from Singletons
rx, Singletons tx, Experiments exp where rx.run = tx.run AND rx.run =
exp.run AND rx.name='receiver-rx-packets' AND tx.name='sender-tx-
packets' group by exp.input order by abs(exp.input) ASC;
does not return any data :)

this how ever works fine in stable release.
Probably something with data gathering

this until Tom H pointed it out [1]. There was a minor change
recently to the stats code that altered the database schema. Much
like you guessed, that change was not propagated to the example script
so it gathered no data. The trivial fix has been pushed to ns-3-dev.
Thx
