Hover Mode

Documentation

The Chart and PieChart components support different modes of series hovering. This demo shows the «includePoints» mode, when all the points of a hovered series change their display style. In addition, you can specify a custom hover mode for legend items. Here, the «excludePoints» mode is used, when only the series line changes its display style leaving the points as they were.
