Echarts

发布时间：2024-12-30 10:50

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。

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) } ] }); });

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; },
