I'm working on a tree map and its way too clutter due to the large number of items in the data.
Is there way to limit the number of items showing in a tree map? I want the top N items based off sales.
In the Chart Properties - General, you can enter a value in "Maximum Slices Before Other" and that will limit. Make sure you also have your sales metric in the sorting properties and set to descending.
Have you tried sorting based on sales in your graph and then setting the row limit (under filter and sort) to be N?
