fusioncharts 刷新 中文 主推
fusionchart的debug模式
<script type="text/javascript">
var myChart = new FusionCharts("../FusionCharts/Column2D.swf", "myChartId", "600", "300", "1", "0");
myChart.setDataURL("Data.xml");
myChart.render("chartdiv");
</script>
对应构造方法参数含义
1.URL of SWF file of the chart type that we intend to use
2.Id for the chart - You can give any id for the chart. Just make sure that if you're using multiple charts in the same HTML page, each chart should have a unique Id.
3.Required width and height of the chart.
4.The last two parameters are debugMode and registerWithJS and are normally set to 0. We'll explain those parameters later.
在使用fusioncharts的时候，有时候你可能要修改其默认的提示信息。如在默认情况下没有数据时显示:no data to display,你要实现自定义你可以通过以下方式实现。
fusioncharts3.1中文提示解决
var myChart = new FusionCharts("../FusionCharts/Column2D.swf?ChartNoDataText=无数据显示", "myChartId", "600", "300");
fusioncharts3.2中文提示解决
<script type="text/javascript"><!--
var myChart = new FusionCharts("Column2D.swf", "myChartId", "300", "250", "0", "1");
myChart.setXMLUrl("<chart></chart>");
myChart.configure( "ChartNoDataText", "Please select a record above");
myChart.configure( "InvalidXMLText", "Please validate data");
myChart.render("chartContainer");
// --></script>
3.2的解决方式较好，在3.1的fusioncharts.js中是没有configure这个方法的。此方法出在3.2中倒是有。不足的是现在网上3.2的破解版还不十分完美,swf文件差异较大.

fusioncharts事件处理
官网上支持的事件
Event Name When is it raised? What to use it for?
FC_Loaded(DOMId) When the chart SWF has finished downloading in the user's browser. To hide any loader components that you might have on your page.
FC_Rendered(DOMId) When the chart has finished rendering. This call is made only once per loaded chart SWF (even if new data is supplied to it via setDataURL or setDataXML method). To invoke any further JavaScript methods on chart, or to change the data of chart.
FC_DataLoaded(DOMId) When the data of the chart has finished loading - both in dataXML or dataURL method. To further process data in any other components in your page.
FC_DataLoadError(DOMId) When there was an error in loading data from the specified URL To show an error message to user, or to take a corrective measure
FC_NoDataToDisplay(DOMId) When the XML data loaded by chart didn't contain any data to display To show an error message to user, or to take a corrective measure
FC_DataXMLInvalid(DOMId) When the XML data loaded by chart was invalid (wrong XML structure) To show an error message to user, or to take a corrective measure

chart1.setDataXML("<chart><set label='A' value='10' /><set label='B' value='11' /></chart>");
chart1.render("chart1div");

注意最后两个参数一定是0,1,不然事件方法是不会调用的.
fusioncharts如何处理y轴整数显示问题
有时候我们图的y轴要求显示次数或数量之类的什么。这些都整数，如果放任fusioncharts自动生成DivLines，那就麻烦了，如果你的 yAxisMaxValue%numDivLines!=0的话，你的y轴间隔线上显示的就是小数，不管你怎么调其它的参数都无济于事。所以要真正实现整数显示
你就要自己处理yAxisMaxValue，numDivLines,yAxisMinValue这些值。保证yAxisMaxValue%numDivLines＝＝0.最近记得设置adjustDiv＝0
还有一个特殊情况就是当显示数据value值为0时，y轴也会也小数的问题。这时最好手动设置yAxisMaxValue=5之类的整数
自动设置fusioncharts的yAxisMaxValue，yAxisMinValue.
对于single series我们遍历set的value值取最大值与最小值
对于multi series 我们要取所有DataSet中最大值与最小值
有时为了显示的好看，我们最好将最大最小边界在原来的基础上增加15%的比例，以保证图型居中
<script type="text/javascript">
var myChart = new FusionCharts("../FusionCharts/Column2D.swf", "myChartId", "600", "300", "1", "0");
myChart.setDataURL("Data.xml");
