I'm trying to graph percent of disk storage used. I can't get the graph to display a Y axis with 0 at the bottom and 100 at the top, instead the Y axis is always a bit above the largest value graphed and the smallest value graphed. This isn't really useful looking at a percentage graph to me. If I'm looking at one disk on a server that is 89% full and then switch to a disk that is only 33% full, the 33% full disk will look really full at a quick glance.

I've tried setting the UOM for the value being graphed and tried it as a raw value with the min and max values set, I keep getting the same looking graph. In the case of the disk that is 33.875% used the Y axis is ranging from 33.85%-33.88%.

I'm assuming this is some aspect of rrd. So is there anyway around this?

There is not currently a way to change this, the graphs automatically autoscale using the values that are returned.
