I want to chart the pecentages of total disk space usage on several of my servers.

What I would like to show on the chart is this:

1. Individual server name on the x axis

2. Groupings of column data representing filesystems that are over a percentage threshold (the columns could be a total of 3 or 5 or however many filesystem are over the threshold). These columns would be placed OVER the server name.

Sounds simple, but I've hit a wall in trying to do this.

Thanks in advance
