Show total that number histogram is using (without nulls)

Opened this issue · 1 comments

Not clear how much of the data the histogram represents, if there are nulls.

I think you mean this histogram?

Which when you hover shows this:

I agree that it is totally unclear how it has ignored nulls. Is the %age of all data points or just of non-nulls?

What would you like it to do:

  • Add an extra column for nulls
  • Have some help explaining what it means?
  • Something else?

Looking at the code it measures the percentage out of all rows, but only plots non-nulls.
