将对应的东西传入页面即可
Echarts echarts = new Echarts(legend, newAxis, series,); String jsonString = com.alibaba.fastjson.JSONObject.toJSONString(echarts);初始化Echarts文件
var dom = document.getElementById("xsl"); var myChart = echarts.init(dom); myChart.showLoading({ text : "图表数据正在努力加载..." }); var app = {}; app.title = '多 X 轴示例'; var colors = [ '#5793f3', '#d14a61', '#675bba', "#00FF00", "#FFFF00" ]; option = { color : colors, tooltip : { trigger : 'axis' }, dataZoom : { show : true, start : 0, realtime : true }, legend : { data : [] }, grid : { top : 70, bottom : 50 }, calculable: true, xAxis : [ { type : 'time', boundaryGap : [ 0, 100 ], axisLabel : { textStyle : { fontSize : "10px" } } } ], yAxis : [ { name : [], type : 'value', } ], series : [] }; myChart.clear(); myChart.setOption(option, true);看完上述内容是否对您有帮助呢?如果还想对相关知识有进一步的了解或阅读更多相关文章,请关注创新互联行业资讯频道,感谢您对创新互联的支持。
