最近把FusionCharts 3.2.1升級到XT版本了，默認情況下，我利用以下代碼渲染JS圖表：

FusionCharts.setCurrentRenderer('javascript');

此前，我們的系統被設置為從XML數據中渲染Flash圖表，并且我未對代碼做任何修改。我在控制臺中看到下列錯誤：

Uncaught ReferenceError: parseTooltext is not defined FusionCharts.HC.Widgets.js:193

 dash.renderXML (dashboard.js, line 40) calls chart.setDataXml() with the following xml:

無法渲染儀表，他們顯示為空白框。
