Can we get a feature to independently scale data sources when adding them to a chart. This is particularly useful when you want to compare pretty much anything against an interfaces throughput, for instance CPU usage vs throughput. As it currently stands interface statistics are multiple orders of magnitude larger than most any other data that will be gathered, if you try to graphic it against anything else the graph for the smaller value, such as CPU, looks like a flat line at the bottom of the graph. 3 axis graphs would be required to properly display this.
I've attached an Image of what currently happens and an Image of a mock up.

I'm also voting for fixed scaling!
