in command line it's working

and there is no gap or hole in the graph

[Howie]

You still get quite a lot of nans on the command line, but it's true that the results should match.

I've never seen that problem before.

Try 'SET rrd_use_poller_output 1' at the top of the map config, and wait a few poller cycles. That will get data directly from the poller instead of from rrdtool.

thank you, no error at all now

really strange !
