| | 21 | <p>This tests that tick marks don't break when the axis crosses into |
| | 22 | daylight savings time.</p> |
| | 23 | |
| | 24 | <div id="demodiv"></div> |
| | 25 | |
| | 26 | <p>The tick marks should all be on day boundaries or nice hours (6, 12, 18), |
| | 27 | rather than on odd time boundaries like 5, 11, 17 and 23.</p> |
| | 28 | |
| | 29 | <hr/> |
| | 30 | <div id="chart2"></div> |
| | 31 | <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 → 01:55 and then back to 01:00.</p> |
| | 32 | |
| | 33 | <hr/> |
| | 34 | <div id="chart3"></div> |
| | 35 | <p>This chart is analogous to the first, except at a "spring forward".</p> |
| | 36 | |
| | 37 | <hr/> |
| | 38 | <div id="chart4"></div> |
| | 39 | <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> |
