Accessing Measure Definition via Custom Viz ( and running functions in powerbi.DataView )

[tkboisvert]

Hi all,

Had a strange request for a custom visual that displays the Meausure defintion.

The custom viz to display the chart and text required isn't the difficult part, accessing measure definitions seems to be undocumented, or not possible.

Is there any way to request information about the PBI workbook its self? Or metadata about the measure passed to the Viz so I can get the definition direct?

To clarify, by measure definition I mean the actual text definition of a measure ie. [Measure] =  CALCULATE(SUM(table[data])).

Also, is there any way you can run these "functions" that appear in the meatadata of a DataView on a viz?
