PlotColors

Description

PlotColors is a collection that contains all color series of all plot objects.

When a plot is added using the Add() method it automatically creates a color series object and is added to the PlotColors collection.

The order of the add commands determines how the plot colors are sorted. The first information request of Add() will create PlotColors[0], the following information request will create PlotColors[1] etc.

Usage

PlotColors[int PlotIndex][int barsAgo]
