I have a pie chart with 3 dataseries (3 pies). Each pie chart represent answers for question. Each part of each pie chart represent same data (promotor, passive, detractor). Actually I'm able to have only one legend (because legend is the same for all charts) but i can't display for each pie chart what is the question ? What I want ideally is to have on title over each pie chart to show question title. Is it possible ?
