Format a New Measure into Percentage with 2 decimal places on a Line and Stacked Column Chart

See screenshot below. I created a new measure called NP% = (count('Scheduled and Arrived Appts'[New Patient Appts]) / count('Scheduled and Arrived Appts'[Appt Scheduled])) * 100. When that measure is put into a Line and Stacked Column chart, the data label shows too many decimal points. How can I get the data label to show only 2 decimal points?

Thanks in advance!
