    <h2>DST</h2>
    <p>This tests that tick marks don't break when the axis crosses into
    daylight savings time.</p>

    <div id="demodiv"></div>

    <p>The tick marks should all be on day boundaries or nice hours (6, 12, 18),
    rather than on odd time boundaries like 5, 11, 17 and 23.</p>

    <hr/>
    <div id="chart2"></div>
    <p>This chart shows a continuous line going across the "fall back" EST/EDT event. You may need to switch your computer's time zone to Eastern to see this. The x-axis tick marks go from 01:00 &rarr; 01:55 and then back to 01:00.</p>

    <hr/>
    <div id="chart3"></div>
    <p>This chart is analogous to the first, except at a "spring forward".</p>

    <hr/>
    <div id="chart4"></div>
    <p>This chart shows a continuous series which crosses a "spring forward". The x-axis ticks should skip from 1:55AM to 3:00AM.</p>
