Usage Guidelines
Truncation
If text exceeds its maximum width, it will be truncated with an ellipsis and a tooltip will be displayed on hover.
Single vs. Double Column
Tooltips can be displayed in either a single or double column depending on its use case.
A single column tooltip is the default and used for things like a truncated label.
A double column tooltip is used for most chart tooltips to display things like the axis title and its value or a series item and its corresponding value.
Anchor vs. No Anchor
A tooltip has an optional anchor. In some scenarios it is useful to include the anchor of the tooltip as it ties the tooltip content to an exact location (eg. A point on a line chart). If the tooltip is corresponding to multiple data points (ie. Hovering the grid line of a line chart), one should use a tooltip without an anchor.
