NinjaScript > Language Reference > Drawing Tool

Definition

Returns a custom collection of ChartAnchors which will represent various points of the drawing tool.

Note: You must declare this property with the chart anchors used in the drawing tool which you plan on using for iteration. Doing so will expose a simple enumerator which will allow you to to iterate over the chart anchors in which have been defined in this interface.

Property Value

A virtual IEnumerable interface consisting of ChartAnchors

Syntax

You must override this property using the following syntax:

public override IEnumerable<ChartAnchor> Anchors
{

}
