Different color of Line at specific values in graph Panel

Dear all,
I don’t know if this is possible on graph panel, but I want is to on my line graph, each series (or one series) of the graph can have multiple colors based on their values.
For example, I have a series of Temperature with the default color of green, but when at certain point in time the values drop to 20, and when that happens I want the color of my line graph (at that certain time) to be in red.

Will it possbile to do it? I know about overrides but it seems like there is no codintion on the side of overrides (I hope i am wrong with this), how can I do a conditional override?

Thank you folks!
Stay safe!

With kind regards,
