X轴数据太多，显示不全设置

xAxis: [{type: 'category',axisLabel:{interval:0,//横轴信息全部显示rotate: -30 //-30度角倾斜显示},

设置Y坐标的最大值和单位

yAxis : [{name: '流量(m^3/s)',type: 'value',max: 500,axisLabel : {show:true,interval: 'auto',    // {number}rotate: -45,margin: 18,formatter: '{value} ml'    //单位},

数据加个单位：显示相关的label或tooltip都支持formatter，如数值轴你就可以通过axis的axisLabel.formatter做换算控制，支持function

Y轴保留1位小数

yAxis : [{type : 'value',axisLabel: {formatter: function (value, index) {return value.toFixed(1);}}}
],

鼠标悬停数据提示带单位

tooltip: {trigger: 'axis',formatter: "收支统计 : <br/>{b} : {c}万"
},

柱状图数据带上单位

series: [{type: 'bar',itemStyle: {normal: {label: {show: true,position: 'top',formatter: '￥{c}'}}},

柱状图修改颜色

name: '合计工时',
type: 'bar',
itemStyle: {normal: {color: '#00bfff',label : {show: true,position: 'top',textStyle: {color: '#00bfff'}}}
},
