However, there is an anomaly 
If the chart is zoomed out, it tends to close the line between the previous and last retrieved value.
See in my example 1H Graph and 4H same graph

Thanks Filipp!

It Works ! !

I've tried, but in last value I get "0" instead of <<ERROR>>
This is the Transformation
return ($1 < -100) ? null : $1;

Why?

When null is returned on the chart it goes a position itself as value 0

Version 3.6.303

Other methods?

Hi,
is possibile to stop graphing when some value is returned?
In my case Ubiquiti device return -1000 of signal strenght when remote device is not connected via radio.

I need to stop graphing instead of get -1000
