The question is a "constant sum" type question. However, the client wants a pie on the same page of the question showing the number entered by the respondent. For example, 50% are red, 20% are green, than 30% are yellow. The pie will have three slides for each color. And if it is 20% are red, 40% are green and 40% are yellow, the size of each slide has to change to reflect the new percentage.
Does anyone know how to do it?
