The problem is that i have table named customer. In that table there are fields named 'test_name' and 'Region' and further more. In Region field there are two values 'R-1' & 'R-2'.
Now i want to plot a single chart having top 5 test_name of R-1 and top 5 test-name of R-2.(top 5 selection are based on net_sales).
