I have a Mekko chart which looks at the sales for different customers, broken down by the different category of product.
My stakeholder has asked to have a view within the chart of sales growth, so I am wondering if there is a way to create a some sort of flag/a second fact so that within each of the customer/category boxes it says whether the year on year growth is positive or negative?
This could be the percentage change in red or green, or some other kind of flag.
Is this possible? If so I would really appreciate some guidance in how to do this.
