工作：
使用Hbuilder建web工程，加入echarts相关库，根据需要更改K线图及其的提示样式，去除默认提示，使用异步加载echarts的数据，数据格式为json。
需要注意的K线图和5日均线，10日均线的意义，5日均值是根据前4天加上当天的值再除以5来计算的，10日的类似，则可以理解以下算均线的函数：
function calculateMA(dayCount) {var result = [];for(var i = 0, len = data.data.length; i < len; i++) {if(i < dayCount) {result.push('-');continue;}var sum = 0;for(var j = 0; j < dayCount; j++) {sum += data.data[i - j][1];}result.push(sum / dayCount);}return result;}
在官网下载echarts.min.js，同时在网上找jquery的js下载下来。用Hbuilder新建web项目，将js文件放入工程相应的文件夹中。
在index.html中引入两个js文件，就可以使用了。
去echarts官网找典型的K线图例子，放入自己的html页面中，Hbulider右侧则会显示出echarts图
异步加载数据需要使用jquery找到json文件，从中取出数据，然后用Mychart.setOption()方法异步加载数据，类似于这样
myChart.setOption({title: {text: data.title,left: 0},xAxis: {data: data.date},series: [{// 根据名字对应到相应的系列 data: data.data},{data: calculateMA(5)},{data: calculateMA(15)},{data: calculateMA(30)}]});});
注意数据对应的图表。
k线图默认的是股票的tooltip提示，默认提示固定有open，close，highest，lowest等字段，而且有默认的提示样式
如果需要改提示字段，则需要自己设置tooltip中的formatter参数，设置触发器为axis，提示中带有颜色的小圆点是是params的marker，其他的可以根据需要设计。
tooltip: {trigger: 'axis',formatter: function(params, ticket, callback) {var result = "时间："+params[0].name + "<br/>";params.forEach(function(item) {if(item.seriesName=="日K") {result += item.marker + " " + item.seriesName + " ("+item.value.toString().split(",")[1]+"，"++item.value.toString().split(",")[2] + ")</br>";} else {result += item.marker + " " + item.seriesName + " : " + item.value.toString().substring(0, 7) + "</br>";}});return result;},
更改字段后显示可以如下，将默认的highest，lowest，open，close去除了
