Yes, I am realizing that in past word clouds, Score Tracker, and Paintomatic I have the same issue with area vs. diameter and the software I have been using views size as diameter, not area. I’ve made the adjustments to the lee vs. price visuals and will continue that in future visuals. Thanks for the input! kd Posted 10/12 at 01:32 PM

You could improve your paintomatics by separating 4-seamers and 2-seamers Posted 10/13 at 03:07 AM

Kevin,
I think the impact on the viewer is proportional to the area of each circle. I also think that you are sizing the circles with the radius proportional to the fraction of usage of that pitch. But the area is proportional to the square of the radius, so you are greatly increasing the perception of the usage of the most common pitch, usually the fastball. For example, if a pitcher throws 70% fastballs, and 10% each curves, changeups and sliders, I think your circles would be proportioned 49 to 1. Thus biasing the perception of how many fastballs were thrown vs the other pitches. You should set the radius to the square root of the percentage.
