Is there any way to customize the graphs to look more like the one below (MRTG/PRTG)?

For example when I goto an Interface Details page i would like the Percent Utilization graph to look more like the one above. I was playing around with the Chart, Percent Utilization - Line chart in the system manager and was able to make it look like this which I like better, but how can I save this so it appears in the web interface as such?
