[NX-1826] Graph option to not join lines if time between is over a specific value

[netxms-migration-bot]

It would be nice to have the ability to set an option when graphing DCI values to not join lines when the data points have long gaps between.

See attached for graph showing where DCIs have not been collecting data for some time.

Maybe the option could have a Number of seconds between data points to not join line.

Just a nice to have to make the graphs look prettier.

This could be implemented only for DCIs that have regular collection interval (either default or custom). In this case there's no need for configurable interval, we can just take double or triple collection interval.

Actually, implementation that takes current collection interval is not good - e.g. if user changes collection interval from 5 min to 1 min, graph won't be displayed.

Better implementation should store a record in idata that data collection was interrupted.

There's also forum suggestion to mark gaps with some colour

Would that increase data collection db size alot? i.e. for devices that are offline alot (e.g. laptops/workstations), would result in many "empty" data collection points.

I'd guess that only one DB record will mark start of a gap, without any records till values start coming again

Sounds good!

Current implementation shows gap on chart if distance between two adjacent data points exceeds 3x polling interval.
