For some metrics like %CPU and %Disk Time, the scales created in Custom Charts do not make intuitive sense. In the below example, the scale for %CPU goes from 0 - 600. This makes it harder to visually interpret the chart.
Would be nice to fix this for metrics that are percentage values, or perhaps give the user the ability to manually adjust the scales. (This could also be useful to create a unified report in some fringe use cases of running multiple simultaneous load tests against the same server.)
