But I think there is some “dirty” method.
I created 2 new items
Number Chart_limit_low "Linia ograniczająca niska" (group_temperature)
Number Chart_limit_high "Linia ograniczająca wysoka" (group_temperature)
Added them to rrd4j.persist & mapdb.persist file and also to the same group like my outside temperature.
In sitemap created
Setpoint item=Chart_limit_low label="Linia ograniczająca niska [%.0f °C]"
Setpoint item=Chart_limit_high label="Linia ograniczająca wysoka [%.0f °C]"
for limit low set 0 and limit high set 25 and my chart looks better. Because this values remain same all the time so the chart “scale” let’s say will looks same all the time. I know that this is some around method but like for me works fine
This is my first post here - sorry if it’s not perfect
I’m beginner but I would like to share my experience also.
