I have a survey that our field workers use to report on their work out in the field. I also have a dashboard set up for the survey to show a breakdown of different categories. I filtered out the 'null' entries for most of my graphics, but a 'blank' category will appear.
When I look at the data itself, instead of 'null' some of the responses are being recorded as blank instead. The Survey uses a lot of 'relevant' questions, so I wonder if that has anything to do with it. I can go in and manually fix this issue, but the survey gets hundreds of responses and I wanted to know if there is a way to prevent this in the first place.
