start a tick mark at the bottom of the range. This is the expected
behavior, even though it results in unusual numbers along the Y axis.
In a real application, you would probably do one of the following to make
more reasonable tick mark values:
    SetPlotAreaWorld() - have PHPlot re-calculate the range and tick values
Or
    SetYTickAnchor(0) - force a tick at Y=0; this moves all the ticks to
whole numbers.
