I'm preparing some charts, with positive and negative values. I would like to create one pie chart, including all the values (the positive and negative). Of course, this doesn't work as only positive numbers should be considered. So I tried to rewrite the results (to cancel the "-") but it doesn't work. I would like to have "-100" displayed as "100", and the "100" staying at "100", so that I can create my graph.
Does somebody has an idea?
