Create a pie chart with four slices

Hello, I saw Allison LaMotte's template that uses a pie chart. Storyline: Animated Charts & Graphs - Downloads - E-Learning Heroes (articulate.com) I love the graphics and would like to know how you changed the size of the pie slices.  I need a four-slice and a six-slice pie to add a different color to each slice, but I can't figure out how to make the pie in the Storyline 360 so I can change the colors. Does anyone have suggestions or templates for sharing four slices of pie?

I made the pie chart in PowerPoint, but when I bring it into Storyline, I can't change the colors, and I have issues maintaining the size of the slices.

Thank you
