Regression between AppManager 9.0 and 9.1 wrt to reports of CPU usage

Hi,

We've been using Application Manager for quite some time here at the company where I work. A few days ago, the Win2k3 server where the Application Manager was running suddenly died due to hardware issues. While migrating the Application Manager database from the old server to the new one, we decided to update the Application Manager to the latest available version at the same time (to build 9130).

The Application Manager itself works fine. However, we've noticed that the type of the graph used by the weekly report of the CPU usage of the servers (AttributeReport) has changed between these two versions. The old graph was a line graph, while the new one is a histogram. I've been looking for a way to get the old graph back, but didn't succeed. Do you have any idea how we can revert the graph type to the old style?

PDF's of the servers CPU usage from the old environment and new environment are attached

Thanks in advance
