Highlight bug with boolean measures

fdanielsouza — Sat, 01 May 2021 02:08:12 GMT

Hi, I noticed that the highlight array have the same values of the data array, but with nulls where points aren't selected. When the measure returns a boolean value, however, the array gives falses instead of nulls, hence we can't highlight a data value of "false", since all values in the highlight array are false. See example below

when the measure returns booleanwhen measure returns anything else

HI @fdanielsouza,

What type of visual and measure formula are you worked on? Can you please share some dummy data to test?

Hi @Anonymous , it's a categorical visual with one category field and a values field that accepts several measures. For highlighting I'm using the options.dataViews[0].categorical.values[0].highlights array to determine if a value is highlighted or not, but the behaviour changes when I use a measure like SELECTEDVALUE([boolean_column]). Instead of give nulls, it give falses. So, if the highlighted value is a false, then the entire array will be of falses, which hinders the highlighting.

HI @fdanielsouza,

I think this may relate to selectedvalue function.

SELECTEDVALUE function - DAX | Microsoft Docs
AFAIK, selectedvalue not suitable for multiple selections. if you do not add 'alternate result' to selectedvalue function, it will invoke 'blank' function to handle this exception result.(mutiple item seleciton)

BLANK function (DAX) - DAX | Microsoft Docs

Handling BLANK in DAX - SQLBI
If you add this optional parameter in selectedvalue function, did these parts still get the wrong results?

I don't think it's related to the function per se, because if I use an implicit measure in a boolean column (like "first this_boolean_column") the problem stands

HI @fdanielsouza,

Have you tried to use a column with other type values? Bool type is different than common visuals and they may affect/conflict with the visual render and analysis. (AFAIK, sometimes they can be defined to control to enable some features)

In addition, you can also contact to power bi team and attach your sample pbix file to help them reproduce and confirm this scenario.

Thanks @Anonymous , so I'll just stick to a warn in the visual's landing page.
