Pareto Analysis: how many references represent n % of your sales ?

Each point represents one reference (Item Code, Brand) with total sales quantity (Pieces) as y-axis coordinate. They are split in groups representing 10% of cumulative sales from highest to lowest sales.

(e.g Dark Blue points are high runners representing top 20% of total sales, [...] Purple points represent the lowest rotation items representing the last 20 % of sold items)
