Graph Builder Histogram Label Size

[#1]

Hello!

Is there a way to change the size of the label on a histogram created in graph builder?  For example, with the "Little Pond" dataset, I created a histogram using column "Z" and then selected "percents".  I want to increase the size of the percents.  Circled below. 

 

Thanks!

I'm not sure you can modify those from graph builder. Some font preference might control those, but I'm not sure

Scripting is also one option, but depending on how you want the labels to work, it might not that that simple script.

Thanks for the reply!  I couldn't find the right preference to change that, but maybe I was looking in the wrong place.  

Thank you!
