I have total cost on columns and total charges in rows. I threw institution name in details to create a scatter plot. I did a calculated field to create a charges / cost ratio. I threw that calculated field in size to change circles size accordantly to the ratio but all circles stayed the same size. What I can do to change circles size based on the charges / cost ratio??
Can you please attach the twbx here? Sounds like you are taking the correct steps. Did you validate your calculated field in a crosstab view?
