Open the Tallest Buildings - Variables.pbix file in the folder shown above. You'll find a matrix showing a count of buildings for each country and city.
A sample of values in the matrix.
Create a new measure called Count of Buildings % of Country and declare a variable to store the count of buildings. Here's some sample code to help you:
You can make up a better name for your variable. Replace the word Expression with code which counts the rows of the Building table.
In the same measure, declare another variable which counts the number of buildings and removes the filter applied by the City field.
You can use the CALCULATE and REMOVEFILTERS functions to do this.
In the same measure, add a RETURN statement which returns the result of dividing the first variable by the second variable. Apply some formatting and display the measure in the matrix.
A sample of the results you should see.
Create a new measure called % of Old Buildings. Create the following variables in the measure:
Variable name | What it should calculate |
---|---|
CountBuildings | The count of buildings. |
CountOldBuildings | The count of buildings whose Year Opened is before 2010. |
Add a RETURN statement which divides the count of old buildings by the count of buildings. Add this measure to the matrix.
A sample of the results.
Save and close the report.
