If the data is not given on the pie chart you can still calculate the percentage each slice is worth or how many items of data are in each slice (if given the total amount of data).

Can a pie chart be more than 100?
Simply put, pie charts are best used to show parts of a whole. Specifically, pie charts should illustrate meaningful relationships between percentages, or parts of 100%. If the data you want to display doesn’t add up to 100%, a pie chart might not be your best choice.
