你的color属性换个颜色呗,似乎并没啥问题，在线试了一下
option = {
color:'#d87c7c',
title: {
text: '商品类别交易额对比',
},
tooltip : {
trigger: 'axis',
axisPointer : {
type : 'shadow'
}
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
xAxis : [
{
type : 'category',
data : [1,23,4],
axisTick: {
alignWithLabel: true
}
}
],
yAxis : [
{
type : 'value'
}
],
series : [
{
name:'Value',
type:'bar',
barWidth: '60%',
data:[1,2,3,4]
}
]
};
颜色没配对。。
