I am working on defect measurement for a QA group. I would like to create a visualization that shows how many defects are open on any given day during the life of a project. I have 'Detected on Date' and 'Closing Date' to work with.
I've toyed with a few ideas using calculated fields, but I'm not getting there? Today is day 2 with Tableau.
To help explain what I mean, I was able to create the below image in Excel. I am not committed to any one chart type.
