v-evelk, additional question. How can one support others' selection in custom matrix visual? I see 

IFilterKeyHierarchyTarget but how to fill it and how to set conditions for all levels of hierarchy? This topic tells that only one filter can be applied.

    I am not sure about matrix. If it uses selectionManger, you can try to use selectionManager with the second parameter as 'true' to enable multi-selection.

     

    this.selectionManager.select(selector, true).then((ids: ISelectionId[]) => {
    //called when setting the selection has been completed successfully
});

     

    Regarding IFilterKeyHierarchyTarget I will ask our engineers and provide info here later.

     

    Kind Regards,

      Yes, I use ISelectionManager to filter data from custom matrix visual.

      Unfortunately, true in select doesn't change the behavior. My custom visuals (matrix and slicer) go to infinite selection loop. Standard line chart shows data selected by matrix for a second. Then it shows data selected by slicer for another second. After that it shows data selected by matrix again. And this process continues until I close Power BI.

      With standard matrix visual all the elements work fine.

        Probably standard matrix uses filters too.

        I am not sure that it is possible to merge filters and selections, you should use one of these approaches if you want to combine selection or filtration.
