How to reference a Plot or a Line

[Taddypole]

In the attached code, I'm trying to color the Zeroline based on the value of "Diff". On lines 90 and 96 of the code, the PlotColors are referencing Index 4. Index 4 is an "Add" statement to add a line in the "Initialize" section. Are Add lines and Add Plots different from an Indexing point of view?

I've been looking at this for a long time and can't figure it out. When Diff is positive I want to color the line Green, when the Diff is negative, I want to color the line Red.

I'd appreciate it if someone can point me in the right direction.

Thanks...

Taddypole, in the code you posted, there are only four Add() references. Please change PlotColors[4][0] to PlotColors[3][0] and see if that fixes it.

Austin,

I tried all values from 0 to 3 and the only one that made any difference is 2. Using 2 for a reference changed the color of the Difference oscillator but not the zeroline. Refer to the attached picture.

I'm totally stumped on this one...

Taddypole, sorry I overlooked this earlier, but to change the color of a line, it must be created as a plot. Please try creating a zero "line" as a plot with a value of 0 every bar and changing that plot color.

Also, in case you haven't seen it, here is the reference sample for how to color plots with the NT7 approach.

if (Diff > 0) Lines[int index].Pen.Color = Color.Green;
else if (Diff < 0) Lines[int index].Pen.Color = Color.Red;

where int index is the index of the line whose color you want to change.

Thank you Austin and koganam...

I now have both methods working.
