Thanks for the help thus far @empet! I now have a semi-related issue with changing format fields on button click.
I have a figure with three subplots - one row and three columns to be exact. Is there a way to update the xaxis title for each individual subplot on button click?
I found this page Changing the xy-Axis Titles with Dropdown Menu which shows how to update axis title of a single plot w/ buttons. Unfortunately I cannot figure out how to translate it to work for multiple subplots. Thanks!
