Welcome to Airtable Community! :slightly_smiling_face:
In order to see the numbers and percentages on the charts, the only way currently is to hover over the part which you want to see the number. Unfortunately you cannot print it with a number (or print it at all as a matter of fact). What I currently do is take a screenshot and enter the numbers manually which is not ideal I know, but there is a post in the Product Suggestions section regarding this feature request. You can add your cote to it there.
If this reply helps you, please mark it as Solution so others can see it.
