Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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 report, and load data from the Excel workbook in the above folder into it.  You should see two tables (Episodes and Series). 

Use Query Editor to tidy up the Episodes table so that it looks something like this:

Episodes table

You'll need to split the authors column in two, and replace the resulting nulls with blanks.  You should also filter the data to show only episodes directed by Daniel Minahan.

Create a pie chart based on this table showing viewing figures by episode:

US viewing figures by episode

Your pie chart should show how many people watched each episode directed by Daniel Minahan in the US.


Save this report as Danny Boy, then close it down.
