Creating Selection manager for Custom visuals with Matrix databind?

Anonymous — Fri, 22 Feb 2019 12:24:18 GMT

Hi guys,

I'm using the Matrix databind and I'm trying to create a selection manager for my visual.

I can't seem to find simple documentation/examples for creating a selectionid to attach to my datapoints - categorical is pretty well documented and I have made that work on other visuals, but Matrix databind doesn't seem to be so popular and the data structure is different and doesn't seem to simply slot into the method that is commonly used in categorical.

I only really care about one selecting dimension of the data if that makes it easier.

Can anyone help? Thanks in advance.

Hi,

You are right, documentation is still in progress and not all moments are described.

To solve your question you can look at Sunberst visual (https://github.com/Microsoft/powerbi-visuals-sunburst/blob/41cfe43d2402330d4d60c16caa17d391635014e8/src/visual.ts#L512)

In general, it uses matrix binding and just converts data to DataViewCategoryColumn type and then adds it to selectionIdBuilder.
