1、设计思路
（1）由于FusionChart的数据源格式有两种：XML和JSON，设计用两种格式提供数据源
（2）两种格式又分为路径格式（XMLUrl和JSONUrl）和字符串格式（XMLData和JSONData）
（3）根据上述情况，设计出四种格式，分别为XMLUrl、JSONUrl、XMLData和JSONData
（4）获取当前时间和当前秒数
（5）利用JQuery定时器原理
（6）采用定时器，结合hide()和show()方法，让四个图依次隐藏和显示
2、利用XML提供的静态数据来作为数据源
Data.xml：
<?xml version="1.0" encoding="UTF-8"?>
<chart yAxisName="Amount" caption="Person(1XML)" numberPrefix="$" useRoundEdges="1" bgColor="FFFFFF,FFFFFF"
showBorder="1" showValues="0" baseFontSize="12">
<set label="Monday" value="25000" />
<set label="Tuesday" value="35000" />
<set label="Wednesday" value="42300" />
<set label="Thursday" value="35300" />
<set label="Friday" value="51300" />
<set label="Saturday" value="64500" />
<set label="Sunday" value="88900" />
</chart>
3、利用JSON提供的静态数据来作为数据源
Data.json：
{
"chart": {
"yAxisname": "Amount","caption": "Person(2JSON)","numberPrefix": "$","useRoundedges": "1","bgColor": "FFFFFF,FFFFFF","showBorder": "1","showValues":"0","baseFontSize":"12"
},"data": [
{
"label": "Monday","value": "25000"
},{
"label": "Tuesday","value": "35000"
},{
"label": "Wednesday","value": "42300"
},{
"label": "Thursday","value": "35300"
},{
"label": "Friday","value": "31300"
},{
"label": "Saturday","value": "64500"
},{
"label": "Sunday","value": "88900"
}
]
}
4、利用XML拼接字符串提供的静态数据来作为数据源
var strXML = '<chart yAxisName="Amount" caption="Person(3XML)" numberPrefix="$" useRoundEdges="1" bgColor="FFFFFF,FFFFFF"'+ 'showBorder="1" showValues="0" baseFontSize="12">'+ '<set label="Monday" value="25000" />'+ '<set label="Tuesday" value="35000" />'+ '<set label="Wednesday" value="42300" />'+ '<set label="Thursday" value="35300" />'+ '<set label="Friday" value="51300" />'+ '<set label="Saturday" value="64500" />'+ '<set label="Sunday" value="88900" />'+ '</chart>';
5、利用JSON拼接字符串提供的静态数据来作为数据源
var strJSON = '{"chart": {'+
'"yAxisname": "Amount",'+
'"caption": "Person(4JSON)",'+
'"numberPrefix": "$",'+
'"useRoundedges": "1",'+
'"bgColor": "FFFFFF,'+
'"showBorder": "1",'+
'"showValues":"0",'+
'"baseFontSize":"12"'+
'},'+
'"data": ['+
'{"label": "Monday",'+
'"value": "25000"'+
'},'+
'{'+
'"label": "Tuesday",'+
'"value": "35000"'+
'},'+
'{'+
'"label": "Wednesday",'+
'"value": "42300"'+
'},'+
'{'+
'"label": "Thursday",'+
'"value": "35300"'+
'},'+
'{'+
'"label": "Friday",'+
'"value": "31300"'+
'},'+
'{'+
'"label": "Saturday",'+
'"value": "64500"'+
'},'+
'{'+
'"label": "Sunday",'+
'"value": "88900"'+
'}'+
']'+
'}';

7、显示结果
（1）初始化
（2）点击“开始计时”
8、设计缺陷
在设计定时控制四个图依次隐藏和显示，但是最后一个图完成后，第二个图无法显示出来，如图所示：
