Pie Chart SAP BO 4.1 - Web Intelligence

Hello,

I need to design a pie chart (in web Intelligence) to show the success actions over the total actions (%). In this case I have two measures from universe in my report (success and error) . I don´t need dimensions.

I give you an example:

Sucess=700

Error=300

I need to design a pie chart in wich I show the sucess in one color (70%) and the error in another (30%).

I try to do it, but my chart is not correct.

Somebody could help me?
