I have created the Gauge visual of my data using ask question by dobule click on the screen and visual is created. In this visual I had asked for the comparison of two date columns (Actual completion date on or before planned completion date). Visual got perfectly fine and in filter with the name "Actual completion date on or before planned completion date" appeared but it is not editable. I cannot edit it.
My suggestion is in advance filter one should be able to compare one column data with other column data.
