Is there possible to make an opportunity to change color of line on a certain value?
Example:
There is one red booster line on graph reflected on "0" Y-axis and has "0" value.
When the value becomes "1", color of line changes to blue (for example), but reflects also on "0" Y-axis.
When the value becomes "0" again, line changes back to red.

Or maybe you have made solution to reflect changed color of line on event or value to show graph like on screenshot? Or maybe there is another way to make some manipulation with two lines, and one can appear from some value to another, and another line with different color can appear after...

Thank you
