Definition

A collection of prior back brushes used for the background colors of the chart panel.

Property Value

A brush series type object. Accessing this property via an index value [int barsAgo] returns a Brush object representing the color of the background color on the referenced bar.

Syntax

BackBrushes

BackBrushes[int barsAgo]

Warning: You may have up to 65,535 unique BackBrushes instances, therefore, using static predefined brushes should be favored. Alternatively, in order to use fewer brushes, please try to cache your custom brushes until a new brush would actually need to be created.

Examples


protected override void OnBarUpdate() { if (CurrentBar < 1) return; // Sets the color of the background on the current bar as blue BackBrushes[0] = Brushes.Blue; // Sets the color of the background on the previous bar as orange BackBrushes[1] = Brushes.Orange; }
