What is PID climate heating on a graph?

When I graph a PID output there is “heating” orange background:

What is this? It makes no sense to me, there is the setpoint (yello line) and input value (the blue line), and there is output from PID regulator (not on this graph). I do not know what this “heating” means. What does it mean? Can we exclude it from the graph? How to graph only the setpoint?

Is this binary value that is on when the output from PID is increasing in the current calculation when compared the previous output value from the PID regulator? (i.e. equal to the sign of the derivative of PID reguilator output?)

Thank you.

I haven’t used the PID climate integration, but for other climate entities that shading represents when the heater or air conditioning is actively running. Here’s what the history for the Bang-bang climate entity that runs my fridge looks like.

… the blue shading is when it is actively cooling

I don’t see any way to exclude it fully, but you should be able to hide it, at least temporarily by clicking on its label in the graph legend.

Can confirm that it’s the same for PID; it just represents a binary state of heating on.
