Legend in marimekko chart

[globalbear]

Hi gurus,

I am trying to use a marimekko chart to visualize how many orders in every month that is handled within three different time spans. I think a Marimekko chart will do the job pretty good. Now - a weird thing about the legend. Notice that the chart shows the best orders (green) at the bottom and the worst (red) at the top. That's looking good. But - the legend is turned upside-down. The green label is at the top and the red at the bottom. This is very confusing!


I googled for Marimekko charts in cognos and found this site:

Notice that the legend is upside down compared to the data!

Is this what's supposed to happen? Is there a way to twist the order of the legend without messing with the data?
