Dynamic count by average over a dynamic date range

[Anonymous]

I am trying to create a calculation for a dashboard that will give me a count of negative margin customers over a timeframe.  The data set that I have has multiple shipments for the month(s) by customer and or SKU.  I would like to average the margins for that customer over the time period selected in the slicer and capture that count into a box/tile on a dashboard.  A sample of the dash board is pasted below.  Any ideas on how to make this work?
