I have a dashboard with two bar charts, one that shows summary sales data by region, and one that shows sales details by rep and sales opportunity. The charts are colored by sales stage. I'm attempting to use the summary chart as a filter... it works when I initially click on a region to filter, but when I deselect that region, the sales stage filter from the source sheet for the details view is cleared. I've played with different configurations for controlling sheets, but without luck. Any thoughts?
