Legend provides information about the series rendered in the Stock Chart. Legend can be added to a Stock Chart by enabling the visible option in the legendSettings.

Position and Alignment

By using the position property, legend can be placed at Left, Right, Top, Bottom or Custom of the Stock Chart. The legend is positioned at the bottom of the Stock Chart, by default.
