Hi,

Here is the inspected select element. The labels are undefined, but the values are correct, therefore the drill downs work.

 

Thanks,

Alexis

Hi alexisc67,

 

Looks like Drill-down by multi columns is not supported by Power BI Custom Visuals API.

 

Have you tried to specify a single column name instead two columns?

    Hi Ignat,

     

    It seems it is suportted. It is just the labels in the drop down that do not show. The functionality is there. I am able to drill down in the two columns with success. The first one is the origin an the second is the destination.The code seems to be there to support it but with a defect on the labels as you can see in the screenshot above with the select xml element. I don't think this is custom code for the visual, I think this widget is in the core Power BI. Can you check that?

    In the screenshot below you can see a function/property $ctrl.canDrillOnMoreThanOneRole()

     

     

    Thanks,

    Alexis

    Hi v-viig,

     

    I also added the same code to the Sankey diagram. See below. The same happens with the labels, but the funcitonality is good, i can drill in Source and Destination. I hope you can find some informaiton about this.

      We'll consider this issue in upcoming versions of Power BI Visuals API but we can't share any ETA so far.

        Hi,

         

        Thanks. Maybe you can add it to the list of Quick Wins since this should take just a few minutes for you guys. Will you keep this in a list or how you track it?
