A shared tooltip is a single tooltip that highlights all data values for a single X value in the chart.

In a chart containing mixed chart types, you often require displaying multiple Y values for a common X value through a single tooltip. In such cases, FlexChart tooltips can be used as shared tooltips by setting the ToolTipContent property accordingly.
