- This controls like a slideshow, you can move from week to week by clicking on the table and even using the arrow keys, at the botton there's an option that lets you jump into a specific week.

- If the data cell is empty it means data is missing.

- Yellow cell means the game was released that week.

- To see dates please refer to the first option.

- Empty data cell means the game hadn't been released that week.

- If the data cell reads "0" it means there's no data for the game on that week, not that it sold 0 units.
