                the graph will plot the average of the values, along with error

    units: The string unit of measurement for the given |data_point|.
    show_on_waterfall: Whether or not to display this result directly on the
                       buildbot waterfall itself (in the buildbot step running
                       this test on the waterfall page, not the stdio page).
