1、問題背景
設計一條折線圖，但是圖形中不用插件自帶的顏色，需要自定義線條和折點的顏色
2、實現源碼
（1）圖形自分配顏色
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>echarts-設置折線圖中折線線條顏色和折線點顏色</title> <link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png"> <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: "微軟雅黑"; 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:['銷售量'] }, 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:'銷售量', type:'line', stack: '銷售量', data:[220, 132, 601, 314, 890, 230, 510] } ] }; echart.setOption(option); }); </script> </head> <body> <div id="line"></div> </body> </html>
（2）線條自定義顏色
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>echarts-設置折線圖中折線線條顏色和折線點顏色</title> <link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png"> <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: "微軟雅黑"; 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:['銷售量'] }, 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:'銷售量', type:'line', stack: '銷售量', 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）折點自定義顏色
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>echarts-設置折線圖中折線線條顏色和折線點顏色</title> <link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png"> <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: "微軟雅黑"; 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:['銷售量'] }, 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:'銷售量', type:'line', stack: '銷售量', 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、實現結果
（1）圖形自分配顏色
（2）線條自定義顏色
（3）折點自定義顏色
4、問題說明
（1）設置折線線條顏色
lineStyle:{
color:'#00FF00'
}
（2）設置折線折點顏色
itemStyle : {
normal : {
color:'#00FF00'
}
}
