How to set two categorical vew mapping

[ysapiyev]

hi everyone,

I need to set two categoricl vew mapping. I looked to example of combo chart capabilities, however it does not work in my visual.

I have two categorial view, values in second are correct, however, categories are same as in first view. What can be the problem?

Do you want ot use two or more categories in your own custom visuals?

Can you share your current capabilities.json?

@v-viig,

Did you have a chance t look at my capavilities file? I'm stack at this problem.

As far as I know, Power BI Custom Visuals API doesn't support two or more dataViews.

Please use the single dataView in categories to resolve the issue.

@v-viig,

Ok. Thank you. 

Since visuals don't support more than one dataview, why does combo chart's capabilities file have three of them?

What combo chart are you talking about?

@v-viig,

Here is the link to file, which I'm talking about: https://github.com/Microsoft/PowerBI-visuals-core/blob/master/src/Clients/Visuals/capabilities/combo...

[v-viig · Accepted solution]

It's native Power BI visuals. Multi data views are not supported by Power BI Custom Visuals API.

Please also note this repo is deprecated. Pleae don't rely on code in this repo anymore.

Here is my capabilities file. As I understood from tutorial on github, second dataviewmapping will result in two categorical data with different categories and values. When I use this code, I have two categorical data, but categories from first one also displayed in second one, whereas there is no "check_cat". At the same time, data for second categorical view displayed correctly.
