That will require custom statistics with the sizings you want - see
this guide for the basics on custom statistics creation and
this guide for a deeper walkthrough. The exact type of statistic will depend on the type of data you want to see. You could build custom statistics based on the size of the bet made from the perspective of the player making the bet or from the perspective of the player facing the bet. The calculation for each is different - for example if a player bets $10 into a $10 pot (100% of pot) then the bet faced by the other player is now 50% of the pot (10/20). This definition is necessary in order to distinguish between situations where a bet has been called in between or not as that changes the pot odds for players facing the bet so if you have multiway hands and are using the bet faced percentage then you might want to exclude multiway hands.
