Hi Rickard,

We have tested the reported scenario and it is working fine in the latest version of the chart 19.3.55 with the lodash file. Unfortunately we are unable to reproduce the reported scenario. Please find the sample used for testing and screenshot for your reference. We have also attached our demo sample link with multiple selection for your reference.

</ChartSeries>

<ChartSeries DataSource="@SalesReports1" XName="X" YName="Y" Type="ChartSeriesType.Scatter">
