ChartRectangle

interface cAlgo.API

Represents the Rectangle chart object. A rectangle of any preferable size and rotation that can be drawn directly in the chart, bound to X-Y axises.

Environment behaviour

CLI — works differently. Created and kept with all its properties, but never drawn: the CLI displays no chart.

Cloud — works differently. Created and kept with all its properties, but never drawn: the cloud displays no chart.
