| 14 | <h1>Potential Y Axis formatting problems for small values</h1> |
| 15 | |
| 16 | <p>The problem using default y axis formatting for very small values:</p> |
| 17 | <div id="graph1"></div> |
| 18 | <script type="text/javascript"> |
| 19 | new Dygraph( |
| 20 | document.getElementById("graph1"), |
| 21 | [ |
| 22 | [1, 0.0], |
| 23 | [2, 0.0001], |
| 24 | [3, 0.0002], |
| 25 | [4, 0.0004], |
| 26 | [5, 0.0005] |
| 27 | ], |
| 28 | { |
| 29 | stepPlot: true, |
| 30 | labels: ["X", "Data"] |
| 31 | } |
| 32 | ); |
| 33 | </script> |
| 34 | |
| 35 | <p>The solution using a Y axis formatting function:</p> |
| 36 | <div id="graph2"></div> |
| 37 | <script type="text/javascript"> |
| 38 | new Dygraph( |
| 39 | document.getElementById("graph2"), |
| 40 | [ |
| 41 | [1, 0.0], |
| 42 | [2, 0.0001], |
| 43 | [3, 0.0002], |
| 44 | [4, 0.0004], |
| 45 | [5, 0.0005] |
| 46 | ], |
| 47 | { |
| 48 | stepPlot: true, |
| 49 | yValueFormatter: function(x) { |
| 50 | var shift = Math.pow(10, 5) |
| 51 | return Math.round(x * shift) / shift |
| 52 | }, |
| 53 | labels: ["X", "Data"] |
| 54 | } |
| 55 | ); |
| 56 | </script> |
| 57 | |
| 58 | <p>Different yValueFormatter and yAxisLabelFormatter functions:</p> |
| 59 | <div id="graph3"></div> |
| 60 | <script type="text/javascript"> |
| 61 | new Dygraph( |
| 62 | document.getElementById("graph3"), |

| 65 | [2, 0.0001], |
| 66 | [3, 0.0002], |

| 70 | { |
| 71 | stepPlot: true, |
| 72 | yValueFormatter: function(x) { |
| 73 | var shift = Math.pow(10, 5) |
| 74 | return "*" + Math.round(x * shift) / shift |
| 75 | }, |
| 76 | yAxisLabelFormatter: function(x) { |
| 77 | var shift = Math.pow(10, 5) |
| 78 | return "+" + Math.round(x * shift) / shift |
| 79 | }, |
