<td valign="top" class="highlightBlock"><p><span class="text">With this method, however, there can sometimes be problems when you're working with larger chunks of data. This problem occurs due to the limitation on dataXML string length imposed by the browser. When you specify a larger chunk of data using dataXML method, the browser ignores everything after a certain length. This causes FusionCharts to hang (nothing would be displayed on-screen) as the full data has not been supplied to it. Therefore, dataURL method is recommended for larger chunks of data (basically - multi-series/combination charts).</span></p>
