本文实例讲述了jQuery插件echarts设置折线图中折线线条颜色和折线点颜色的方法。分享给大家供大家参考,具体如下:
1、问题背景
设计一条折线图,但是图形中不用插件自带的颜色,需要自定义线条和折点的颜色
2、实现源码
(1)图形自分配颜色

(2)线条自定义颜色
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>echarts-设置折线图中折线线条颜色和折线点颜色</title> <link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png" rel="external nofollow" rel="external nofollow" rel="external nofollow" > <script type="text/javascript" src="../js/echarts-2.2.7/doc/asset/js/jquery.min.js" ></script> <script type="text/javascript" src="../js/echarts-2.2.7/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: ['周一','周二','周三','周四','周五','周六','周日'] }, yAxis: { type: 'value' }, series: [ { name:'销售量', type:'line', stack: '销售量', itemStyle : { normal : { lineStyle:{ color:'#00FF00' } } }, data:[220, 132, 601, 314, 890, 230, 510] } ] }; echart.setOption(option); }); </script> </head> <body> <div id="line"></div> </body> </html>
(3)折点自定义颜色
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>echarts-设置折线图中折线线条颜色和折线点颜色</title> <link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png" rel="external nofollow" rel="external nofollow" rel="external nofollow" > <script type="text/javascript" src="../js/echarts-2.2.7/doc/asset/js/jquery.min.js" ></script> <script type="text/javascript" src="../js/echarts-2.2.7/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: ['周一','周二','周三','周四','周五','周六','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)图形自分配颜色
(2)线条自定义颜色
(3)折点自定义颜色
4、问题说明
(1)设置折线线条颜色
lineStyle:{ color:'#00FF00' }
(2)设置折线折点颜色
itemStyle : { normal : { color:'#00FF00' } }
希望本文所述对大家jQuery程序设计有所帮助。
