Tooltips are pop-ups that appear while hovering over data points or series in a chart. They provide additional, valuable information about chart data in scenarios, as follows:

• Single series chart: Tooltips display data values and series name.
• Mixed charts: Tooltips display multiple data values for multiple series for a single category.
• Pie charts: Tooltips display name and percentage share or value of slices.

A tooltip displays Y value of a data point in FlexChart by default. However, FlexChart allows creating and formatting custom content in tooltips using pre-defined parameters and formats. In addition, the control allows creating a shared tooltip in the case of mixed charts.
