Data Reduction issue in Custom Visual

Anonymous — Wed, 24 Apr 2019 09:33:23 GMT

When DataRole grouping is used in custom visual and Data Reduction Algorithm is applied on that grouping field to support up to 300000 rows, then visual is not rendering that many rows.

In this case if Legend has '25000' rows it is not rendering that many rows in Dataview.

Is there any limitation for Data Reduction when we use DataRole grouping ?

Hello,

As I know this is a limit for number of input data rows but since you use grouping role your data will be grouped so, it is expected that you will see only grouped data which number of rows is usually lesser than number of input rows.
