fusioncharts 用法实例

支持xml格式和json格式的数据。

用法很简单。

1.需要引入FusionCharts.js.

2.html中定义个id="chart"的div

<div id="chart"></div>

3.js代码调用即可

（一）xml格式。

var dataXml = "<graph caption=‘每月销售额柱形图‘ xAxisName=‘月份‘ yAxisName=‘Units‘ showNames=‘1‘ decimalPrecision=‘0‘ formatNumberScale=‘0‘><set name=‘一月‘ value=‘462‘ color=‘AFD8F8‘ /><set name=‘二月‘ value=‘857‘ color=‘F6BD0F‘ /><set name=‘三月‘ value=‘671‘ color=‘8BBA00‘ /><set name=‘四月‘ value=‘494‘ color=‘FF8E46‘ /><set name=‘五月‘ value=‘761‘ color=‘008E8E‘ /><set name=‘六月‘ value=‘960‘ color=‘D64646‘ /><set name=‘七月‘ value=‘629‘ color=‘8E468E‘ /><set name=‘八月‘ value=‘622‘ color=‘588526‘ /><set name=‘九月‘ value=‘376‘ color=‘B3AA00‘ /><set name=‘十月‘ value=‘494‘ color=‘008ED6‘ /><set name=‘十一月‘ value=‘761‘ color=‘9D080D‘ /><set name=‘十二月‘ value=‘960‘ color=‘A186BE‘ /></graph>";

var myChart = new FusionCharts("${base}/thirdparty/FusionCharts/ChartsV3/Charts/Pie3D.swf", "myChartId_00", "500", "400");//参数分别为【需要使用的swf样式】，【chart的id（同一个页面有多个chart避免重复）】，【height】，【width】
//myChart.setJSONData(${jsondata!});
myChart.setDataURL(dataXml);
myChart.render("chart");

（二）json

1. //使用json数据
2. var  MSLine = new FusionCharts("flex/fusioncharts/MSLine.swf", "MSLineID", "460", "350", "0", "1");   MSLine.setJSONData({
3. "chart":{
4. "caption":"Business Results 2005 v 2006",
5. "xaxisname":"Month",
6. "yaxisname":"Revenue",
7. "showvalues":"0",
8. "numberprefix":"$"  },
9. "categories":[{
10. "category":[
11. {          "label":"Jan"        },

68. "trendlines":{

74. },

78. "type":"animation",
79. "param":"_xScale",
80. "start":"0",
81. "duration":"1"
82. }]
83. }],

//如果java代码生成，可以理解为整个是map，chart是纯map格式的，data是map中包含了list<Map>。

Map<String,Object> chart = new HashMap<String, Object>();//图表属性
chart.put("caption", "图表标题");//图表标题
chart.put("bgcolor", "F2F8EF");//bgcolor
chart.put("showborder", "0");//border
chart.put("exportenabled", "1");//export
chart.put("exportshowmenuitem", "1");//export
chart.put("logoalpha", "30");//alpha
chart.put("useroundedges", "1");
chart.put("yaxisname", "Sales Figure");
chart.put("logoposition", "CC");

List<Map<String,Object>> datalist = new ArrayList<Map<String ,Object>>();//组织数据List<Map>

for(Map<String,Object> m :queryListC){
Map<String,Object> map = new HashMap<String, Object>();
map.put("label", "xxx");
map.put("value", value);
datalist.add(map);
}

Map<String ,Object> jsondataMap = new HashMap<String, Object>();//最终json仍然是map，需要把前面的数据放入

jsondataMap.put("data", datalist);
jsondataMap.put("chart", chart);

最终将数据返回js

model.put("jsondata", net.sf.json.JSONObject.fromObject(jsondataMap).toString().replace("\"", "‘"));

以上是fusionCharts的基本用法。fusionCharts功能很强大，能实现精美的图标功能，可以上官网查看demo。
