Why is yes/no field type is not available for grouping?

I am trying to create a chart where the data is grouped by “Compliance Type” and “Status”. However, I am not able to group by yes/no field type? Any pointers on how to aggregate this data based on the status.

Since, I am not able to group by the status, my graph is not able to show the “completed”, i.e. yes and “not completed” i.e. No tasks.

Meanwhile you can have an alternative field that is called “Status Alt” that is a text type with either the text “yes” or the text “no”.

Thanks @vini_brito. It seems my problem is that, I am not understanding the grouping properly to display the data and label properly in the charts.

Fear not, sometimes thing aren’t 100% intuitive in Bubble and software in general.
