Bullet chart with different colored regions?

[highpockets]

Hello all, I am relatively new to Cognos and I'm wondering if anyone can help. I've created a bullet chart which has 4 or 5 categories, each with a different target value. So far so good. However, I'd also like to be able to define different colored regions for each category. For example, category A might have red from 0 to 50, while category B would have red from 0 to 60. Is this possible? Everything I've tried so far has resulted in the same colored regions across all the categories. I even tried a calculation based on my target value (i.e. red from 0% to target * 0.9, yellow from target * 0.9 to target * 0.95, green from target * 0.95 to 100%), but it still has the same colors across all categories. If anyone has any experience with something like this, I'd appreciate it. By the way, I'm using Report Studio 10.1
