[rrd-users] Re: How to create square wave graph.

[Tobias Oetiker]

Jeeva.K,

if you feed your data exactly every 15sec (at 1:00:00, 1:00:15,
...) then you will get a square wave ... else the graph will do the
best it can to aproximate the space below the curve to what you
enter ... then includes 'intermediate' points.

cheers
