When looking at a graph using the settings: Group by: Prompt level, Data: Percentage of total, and Annotations: Average, with the aim of getting the average percentage of each prompt level that has been required over a period of time, hovering over the average lines results in a pop-up saying "Average: " and a percentage, but the percentage is not actually the relevant average and instead appears to be the value of a semi-random data point that happens to be close to the cursor.

I need averages to be clear, easy to read, and reliably/clearly different from data point values; maybe just written right on the average lines in the graph or right below the graph in the key. I need an alternative to exporting data to a spreadsheet and manually calculating averages to ensure they are correct, which is what I'm having to resort to currently.

Thank you so much.
