Hi.
I've got a problem with making a simple burnout chart. I've made a data cube where i summarize story_points for every iterations. And now I have to make I chart where iteration number will be on X-Axis and on Y-Axis i need to have a total story_points -(minus) story_point per iteration.

I suppose that total story_points in my case should work as a kind of global variable, but I did not manage to do it.

Regards,
Krzysiek

PS: Sorry for my english
