1、问题背景

     设计1条折线图,但是图形中不用插件自带的色彩,需要自定义线条和折点的色彩


2、实现源码

(1)图形自分配色彩

(2)线条自定义色彩

(3)折点自定义色彩

<!DOCTYPE html> <html> <head> <meta charset="UTF⑻"> <title>echarts-设置折线图中折线线条色彩和折线点色彩</title> <link rel="shortcut icon" href="../js/echarts⑵.2.7/doc/asset/ico/favicon.png"> <script type="text/javascript" src="../js/echarts⑵.2.7/doc/asset/js/jquery.min.js" ></script> <script type="text/javascript" src="../js/echarts⑵.2.7/doc/example/www2/js/echarts-all.js" ></script> <style> body,html{ width: 99%; height: 99%; font-family: "微软雅黑"; font-size: 12px; } #line{ width: 100%; height: 100%; } </style> <script> $(function(){ var chart = document.getElementById('line'); var echart = echarts.init(chart); var option = { title: { text: '' }, tooltip: { trigger: 'axis' }, legend: { data:['销售量'] }, grid: { left: '3%', right: '4%', bottom: '3%', containLabel: true }, toolbox: { feature: { saveAsImage: {} } }, xAxis: { type: 'category', boundaryGap: false, data: ['周1','周2','周3','周4','周5','周6','周日'] }, yAxis: { type: 'value' }, series: [ { name:'销售量', type:'line', stack: '销售量', itemStyle : { normal : { color:'#00FF00', lineStyle:{ color:'#00FF00' } } }, data:[220, 132, 601, 314, 890, 230, 510] } ] }; echart.setOption(option); }); </script> </head> <body> <div id="line"></div> </body> </html>

3、实现结果

(1)图形自分配色彩


(2)线条自定义色彩
