Create SelectionId for Matrix data

[garysweeting]

Is it possible to create a SelectionID using the Matrix data mapping?

The tutorial covers Categories (https://github.com/Microsoft/PowerBI-visuals/blob/master/Visual/Selection.md#managing-selection-sele...) and the following post suggests that it's not available for Table (http://community.powerbi.com/t5/Developer/SelectionId-for-table/m-p/76506/highlight/true#M2632).

@garysweeting,

At least, seems you can not use the API. Just leave a comment on GitHub.

I received some guidance on how to resolve this, you can create a DataViewCategoryColumn object based on your data. Here's an example: https://github.com/Microsoft/powerbi-visuals-sunburst/blob/master/src/visual.ts#L147

The link is  missing, and we are stuck exactly here. 

Any tips?

This one is for <= API 1.13.0: https://github.com/Microsoft/powerbi-visuals-sunburst/blob/d7e094c1d10d2445d66fbaf3b94e3f5e2bae5fec/...

That one is for >= API 2.0.0: https://github.com/Microsoft/powerbi-visuals-sunburst/blob/41cfe43d2402330d4d60c16caa17d391635014e8/...

The main difference here is how queryName is populated.
