单独添加itemStyle
itemStyle: { color: '#ccc' }

封装
- 主要在series里的itemStyle判断设置颜色
series: [
{
name: 'PM2.5',
type: 'bar',
data: Pm25Ozonedata,
data: [35,75,100,115,150,250,300,500],
itemStyle: {
normal: {
color: function (params) {
var index_color = params.value;
if (index_color <=35) {
return '#00ff00';
} else if(index_color >35 &&index_color <=75) {
return '#f5fc13';
}else if(index_color >75 &&index_color <=115) {
return '#ff8400';
}else if(index_color >115 &&index_color <=150) {
return '#fc0000';
}else if(index_color >150 &&index_color <=250) {
return '#9b004f';
}else if(index_color >250 &&index_color <=500) {
return '#860023';
}
}
}
}
},
