and Edge
.

shared
By default, a tooltip displays information about the currently hovered series point. If you set the shared option to true, the tooltip will display information about all the points that have the same argument as the hovered point at once.
If the text displayed in the tooltip by default doesn't suit your needs, you can customize it using the customizeTooltip option.
zIndex
If the widget's container has the CSS z-index property specified, and tooltips are displayed incorrectly, configure their z-index using this option.
