When using pie charts it is very difficult or even impossible to create comparable charts. Ordering and coloring is all automatic and seems to always represent categories by descending order.
Imagine only 2 categories of data - CatA and CatB. You do 2 graphs showing the percentages these 2 categories show for 2 diferente series.
Since you cannot control de order of drawing you may get CatA first or second in each graph. Worse even, with different colors. It is very difficult to read into those charts.
funny enough in this example colors are the same…
So my question is: is there a way to sort a pie chart? and is there a way to define colors for each “X” category?
