    </AccumulationChartComponent>;

Note: To use tooltip feature , we need to inject AccumulationTooltip module into the services.

We can specify header for the tooltip using header property.

Format

By default, tooltip shows information of x and y value in points. In addition to that, you can show more information in tooltip. For example the format ${series.name} ${point.x} shows series name and point x value.

By default, tooltip shows information of x and y value in points. You can show more information from datasource in tooltip by using the tooltipMappingName property of the tooltip. You can use the ${point.tooltip} as place holders to display the specified tooltip content.
