I want to do customization of Graph screen which is displayed after we select Analysis > Graphs menu option in QC.
Following customization i want to do

1. When you expand the Graph tree, I see all the default graphs like <Summary>, <Progress>, <Defect Age> and <Trend> along with all public/favorite graphs. I want to show users only those graphs which i want him to see. I dont want to show him all the default graphs.

2. Is it possible to cutomize fields in X-Axis and Group By dropdown fields?

Thanks in advance.
