Change color of same line based on different value?

Hello,

Say there is a graph with one trending line on it that covers a two hour relative time window. Is it possible to change the color of this line dynamically over time if it matches a particular threshold?

Would look something like:
If a value is between 80 and 100, the line of the color would be green for the time slice the value represents.
If a value is between 50 and 79, the line of the color would be yellow for the time slice the value represents.
If a value is between 0 and 49, the line of the color would be red for the time slice the value represents.

Thanks,
Adam
