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

};
echart.setOption(option);
});
</script>

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: {

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
