Hi Wayne,
Very good news. My charts are displayed into my ipad project.
In fact it was just necessary to place the chart JS file just before yours into the html file.
It was not really an issue with the chart library.
Others JS chart library works fine with same restrictions.
Here an example to place JS file at the head of file:
<meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″/>
<meta name=”apple-mobile-web-app-capable” content=”yes”/>
<link rel=”stylesheet” href=”pag1.css”/>
<!– Graph’s –>
<script type=”text/javascript” src=”jschart/FusionCharts.js”></script>
<script type=”text/javascript” src=”jschart/lib.js” ></script>
<script type=”text/javascript” src=”data/revenusfr.js” ></script>
<script type=”text/javascript” src=”data/statsweb4.js” ></script>
<!– End Graph’s –>
<script type=”text/javascript” src=”res/jquery-1.3.2.min.js”></script>
<script type=”text/javascript” src=”res/preloadCssImages.js”></script>
<script type=”text/javascript” src=”res/iscroll.js”></script>
<script type=”text/javascript” src=”pag1.js”></script>
<script type=”text/javascript” src=”res/phoneui.js”></script>
<script type=”text/javascript” src=”pag1_custom.js”></script>
And I join 2 pictures of my results.
