dm-p  Daniel,

 

Thanks for detailed answer! It was very helpful. 

I have some questions regarding it. I added it to my line chart, which has categorical dataview mapping, and can I pass to legend grouping of categorical data view? I tried using this:

let categoryRole = options.dataViews[0].categorical.values.grouped();

But it gave me error. 

Also, I don't want to use selection id, if I leave it empty, I get error. 

And finally, even though scrollable parameter is true, I can't scroll:

When I click on arrow, it doesn't work.

 

Regards,

Yerkhan

Hi Anonymous,

I mentioned in my earlier post that you will need to have a selection ID for each entry, otherwise the legend utility will not work. Unfortunately for your case you cannot provide a null value here so will need to provide something valid. It's highly likely that this is causing your legend to break.

    Hi dm-p ,

     

    Got it regarding selection id. How does regular line chart works? It has date as axis, category as grouping for data, and legend is built based on category. I wanted to recreate it, but with cumulative values.

    Hi Anonymous,

    I'm not entirely sure I follow - you can manage cumulative measures with the core line chart and DAX. Is there a specific feature you're trying to manage in your custom visual?

    Thanks,

    Daniel

    dm-p ,

     

    I can't use DAX since I'm using live connection to OLAP cube. I wanted to recreate line chart, but make cumulative calculations inside of visual. However, by legend doesn't work, as I mentioned before.
