Possible to remove legend but keep graph on average CPU chart?

Is there a way to remove the legend on a custom chart when using the data source "CPU Multi Load History/Average CPU Load", but keep the chart?  I'm trying to add this resource to a NOC screen, but with all the CPUs listed, it will take up a ton of screen real estate. See the screenshot below to see the legend.  There are about 20 more CPUs that aren't in the screen capture.
