|---|
| 92 | if any apply to you or may be the source of your problem. |

|---|
| 96 | <h4>Tooltips not working as of the October 2010 release</h4> |
|---|
| 97 | |
|---|
| 98 | <p> |
|---|
| 99 | If you're specifying numbers instead of strings for your tooltips, they will not work any more. Simply cast them to |
|---|
| 100 | strings, like this: |
|---|
| 101 | </p> |
|---|
| 102 | |
|---|
| 103 | <pre class="code"> |
|---|
| 104 | <span style="color: red"> |
|---|
| 105 | // This WILL NOT work any more |
|---|
| 106 | myBar.Set('chart.tooltips', [56, 67, 53]); |
|---|
| 107 | </span> |
|---|
| 108 | <span style="color: green"> |
|---|
| 109 | // Do any of these instead |
|---|
| 110 | myBar.Set('chart.tooltips', ['56', (67).toString(), String(53)]);</span> |
|---|
| 111 | </pre> |
|---|
| 112 | |
|---|
| 113 | <a name="annotations"></a> |
|---|
| 114 | <h4>Annotations aren't saved when running locally in Mozilla Firefox</h4> |
|---|
| 115 | |
|---|
| 116 | <p> |
|---|
| 117 | The solution here is to run the charts using a web server. At this time (March 2010) only Safari, Chrome and Opera |
|---|
| 118 | support saving annotations when running locally. |
|---|
| 119 | </p> |
|---|
| 120 | |
|---|
| 121 | <a name="missing.text"></a> |
|---|
| 122 | <h4>Missing text in Google Chrome</h4> |
|---|
| 123 | |
|---|
| 124 | <p> |
|---|
| 125 | Since one of the Chrome 4 dev releases there has been an issue with Google Chrome 4 and 5, asynchronous processing and not rendering |
|---|
| 126 | chart labels. This has been remedied by simply not using asynchronous processing. Because of the tag placement on the front page, |
|---|
| 127 | the effect shouldn't be apparent. Other browsers (eg Firefox, Safari, Opera, MSIE) are fine. |
|---|
| 128 | </p> |
|---|
| 129 | |
|---|
| 130 | <p> |
|---|
| 131 | <b>Update:</b> Currently, (roughly March 2011), the missing text issue appears to be much less evident, if not resolved entirely. |
|---|
| 132 | </p> |
|---|
| 133 | |
|---|
| 134 | <a name="firefox.tooltips.clipboard"></a> |
|---|
| 135 | <h4>Firefox, tooltips and the clipboard</h4> |
|---|
| 136 | |
|---|
| 137 | <p> |
|---|
| 138 | Firefox, tooltips and using the clipboard is a little convoluted. To copy the text in a tooltip you must do the following: |
|---|
| 139 | </p> |
|---|
| 140 | |
|---|
| 141 | <ol> |
|---|
| 142 | <li style="margin-top: 0">Select the text you want with the mouse.</li> |
|---|
| 143 | <li style="margin-top: 0">Press CTRL+C (it may be a different key combination if you're not using Windows) to copy the text to the clipboard.</li> |
|---|
| 144 | </ol> |
|---|
| 145 | |
|---|
| 146 | <p> |
|---|
| 147 | <b>Note:</b> Recent versions of Firefox 4 (from beta 6 onwards) appear to work as expected, and you can copy text with the mouse as normal. |
|---|
| 148 | </p> |
|---|
| 149 | |
|---|
| 150 | <h4>Shadows in Google Chrome and the line chart</h4> |
|---|
| 151 | |
|---|
| 152 | <p> |
|---|
| 153 | Shadows in recent versions of Google Chrome are somewhat broken. Firefox, MSIE, Opera and Safari are fine. The reason for this |
|---|
| 154 | error is a combination of factors it seems - shadow blurring and line width. Fixes have been added to allow shadow blurring and |
|---|
| 155 | a 1 pixel linewidth, though some chart types may still be affected. |
