SAM Multiple Object Chart - View limitation?

Hi all!!

We have a Multiple Object Chart (MOC) for monitoring the CPU of 45 servers (as an example).  Questions:

1. In the current version of SAM 6.x, is the label display above the chart limited to showing only 30?
2. If so, is the actual data from all 45 servers represented in the chart?
3. If so, is it possible to change this?
4. Would it be possible to have a single MOC that contained data displayed individually from multiple resources, but NOT show the labels (takes up valuable space), and allowed you to view the source by hovering over the data points / lines?

Thanks!
