Is there a way to solve for the top 20% of an expression and then plot it? Also, is there a way to solve for the average of an expression and then plot it?
I have Month as the Dimension and am looking to do a combo chart. I am looking to add three expressions.
1. Avg (Sales) - which I can plot as a bar chart
2. Avg of the Top 20% of (Sales) - Though here I need to average out the sales of the top 20% of achievers
3. Avg of all (Sales) Here I need to average out the sales of all achievers
Any ideas?
