You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Create a new Power BI Desktop file, and load the tables from the workbook in the above folder into your model. Using variables, create a measure which allows you to show this matrix:
The matrix shows for each cell the ratio between sales for that cell and sales for four- and six-legged animals for the same filter context.
Here's a suggestion of variables to create within your measure:
|Variable||What it could equal|
|FourLeggedSales||The total quantity of sales for the current filter context, but for animals with 4 legs|
|SixLeggedSales||The total quantity of sales for the current filter context, but for animals with 6 legs|
|ManyLeggedRatio||A/B, where A = the total quantity of sales for the current filter context, and B = the sum of the previous two variables|
Save this workbook as Variable fun, then close down the Power BI instance you're using.
