@TimLudwigsen The approach generally depends on what fields are in your data and how you want to display it. If you are using a Period Over Period chart, then you need to have a date field in the x-axis in order to set up a comparison to prior year and dynamically change the date groupings. You will also have to select a comparison (i.e. Previous Year) within Analyzer and save the card for any comparisons to be available.
