Tutorial - Rolling Average Across Matches
Today I am going to focus more on a calculation rather than the visual. For this video, I will focus on a rolling average across matches, rather than days. This requires an extra step to calculate an index value for the match date. In a future video I will show a different method for doing this as well for different types of data.

Import Notes for Calculated Columns
There are a few important things to keep in mind when working with calculated columns.
- Columns are calculated on data load and so cause your model to load slower, depending on the size of your data model.
- Because the column is calculated on load, adding a dynamic value to the calculation is not possible. Such as changing the rolling match period.
- This is possible using a measure and I will provide a video for this in the future.
Hope this video was insightful and helps you to create your rolling averages.
