Hi,
I was wondering if it is possible to choose how history data is displayed ?
For instance, I have a sensor giving only integer numbers, but are dislayed as a timeline, with is not very logical… Is there a way to force it to plot data in a graph

Let’s say something like “ppm” (points per minute), or something more appropriate in your language. Whatever you pick, add a line like this (then restart):

unit_of_measurement: ppm

Once the sensor has a unit of measurement it should display on a graph. Be forewarned, though, that for a while it will probably show as a combination of a line (with the old values) and a graph (with the new values.) At some point it should show strictly as a graph.
