I have sensor which gives a lot of output, and it logs to a graph.
Many points will slow down the graph, and the output does not change often - but when it does I want to see it.
I use the RBE node to reduce the amount of data in the graph, but:
If the value does not change for 5 hours and then suddenly spikes, I get an ugly and incorrect interpolation from the last point (5 hours ago) to the new spike-value. It shows a slope over 5 hours when in reality, the signal was steady and only spiked after 5 hours.
Can you make the RBE node either
- so that it outputs some values, like at least every N seconds, or at least every Nth value?
It would be in effect a data-reducer but not a 100% limiter.
- or so that when the value changes it quickly outputs the last 'normal' value, followed by the spike? That way graph- interpolation would be correct.
