Fractional milliseconds issue

[SemmZemm]

If I use x=[1486549278145, 1486549278145.02, 1486549278145.04, 1486549278145.06, 1486549278145.08, 1486549278145.1] the graph doesn't display anything at all

Thanks @SemmZemm - another one related to our rounding precision. Short-term I'm going to just enforce the 0.1ms minimum here, until we decide on something better to do in #2893
