开源 E-ChartSdk 的使用方法

SVN 源码地址：http://code.taobao.org/svn/keshihua-echarts/

1.1、如何声明

var sdk = new ChartSdk();

 

1.2、加载JS中的图表模板option

var option = sdk.js(“option_line.js”);

 

1.2、加载后台JSON数据，本方法采用done异步模式

var url = “saledata-columnarrays.json”;
//url = “Data/getSaleData.ashx?date1=2002&date2=2004″;

sdk.json(url).done(function (data) {

});

 

1.3、后台JSON格式
请参照 x1/saledata-columnarrays.json

{
“年月”:["2002.01","2002.02","2002.03","2002.04","2002.05","2002.06","2002.07","2002.08","2002.09","2002.10","2002.11","2002.12","2003.01","2003.02","2003.03","2003.04","2003.05","2003.06","2003.07","2003.08","2003.09","2003.10","2003.11","2003.12"],

1.4、获得JSON对象的属性名称数组,按照序列访问

var propNames = sdk.propNames(data, 1,5);

 

1.5、获得JSON对象的属性值，按照序列或名称访问

按照名字

var dateTimes = sdk.prop(data, “年月”);

或者 按照序列

var dateTimes = sdk.prop(data, 0);
