Hello
I am new with grafana to prepare my io broker data and display it on a dashboard.
This also works to a certain point to my satisfaction.
I have written 3 querys which show me the outdoor, forward and return temperature of my solar system.
However, I am missing one point. the operation of the charge pump.
I have this value. As a true when the pump starts and a false when the pump stops.
I would like to show the part of the graph with a light green background (bar chart) when the pump is running.
Since I also have the outside temperature, this can be in the negative range. So my y-axis can start at -15 and solar flow is at 90 degrees.
How do I get the pump to cover this range completely?
I have created this with rrd tools by writing a rather complicated PHP routine.
ince solar does not show a pump in my old system, I chose my gas heater.
Can someone explain me how to get a height flexible y-axis background design with only one start and one stop point?
thank you grant2
Of course that would be possible. However, I have then set the range and cannot see the fineness which is very helpful for optimisations. Also, moving the temperature to its own y axis consumes the image extremely.
So it looks like I have to insert a mathematical function with blocki or node red in advance. I thought that this would be possible in grafana.
Have you considered using a second y-axis for only certain fields? That would allow you to put both on the same graph and hopefully still retain the “fineness”.
