Hi Volker, 

Greetings from Syncfusion. 

We request you to use TooltipMappingName property to bind and display data for tooltip from dataSource. We have prepared sample based on your requirement and attached for your reference. 

Code Snippet :  

<SfChart> 

    <ChartTooltipSettings Header="${point.tooltip}"></ChartTooltipSettings>     

    <ChartSeriesCollection>

    </ChartSeriesCollection> 

</SfChart>
