接着上一篇文章补充一点项目中遇到的问题及解决方法
1、y轴正负轴调换
yAxis: {
inverse: false, //y轴正负轴调换
},
2、去掉图表背景线
yAxis: [
{
type: 'value',
name: '占比',
splitLine:{
show:false //背景横线不显示
},
}
]
3、y轴以百分比显示
yAxis: [
{
type: 'value',
name: '占比',
axisLabel: {
formatter: '{value} %'
},
]
4、y轴刻度设置最小/最大值
yAxis : [
{
type : 'value',
minInterval: 1，
maxInterval:100
}
],
5、设置y轴刻度显示保留几位小数
yAxis: {
type: 'value',
axisLabel: {
formatter: '{value} ',
formatter: function (value, index) {
return value.toFixed(2); //保留两位小数
}
}
},
6、饼图文字在扇形内部显示
series : [
label: {
normal: {
position: 'inner'
}
}
]
下面贴几个最近做的echart的demo希望可以帮助到一些朋友
1、在图表中添加平行于y轴和x轴的线以及趋势线（如下图）
代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<input type="text">
<div id="pic0" style="width: 600px;height:400px;"></div>
<script src="js/echarts.js"></script>
<script>
var myChart14 = echarts.init(document.getElementById('pic0'));
option14 = {
title: {
text: '未来一周气温变化',
subtext: '纯属虚构'
},
tooltip: {
trigger: 'axis'
}, xAxis: {
type: 'category',
boundaryGap: false,
data: ['100','200','300','400','500','600','700']
},
yAxis: {
type: 'value',
axisLabel: {
formatter: '{value} '
}
},
series: [
{
name:'最高气温',
type:'line',
data:[100, 200, 300, 400, 500, 600, 700]
},
{ //平行于y轴
name:'',
type:'line',
markLine: {
name:'盈亏临界点',
symbol:'circle',
lable:{
normal:{
show:true,
position:'end',
formatter:'盈亏临界点'
}
},
data: [[
{coord:['400',0],value:1}, //{coord:[4,0],value:1},//此处的4不加引号表示横坐标第几个从0开始
{coord:['400',350],value:400}//如何获取grid上侧最大值，目前是写死的
]]
}
},
{ //平行于x轴
name: '线',
type: 'scatter',
symbolSize: 20,
markLine: {
lable:{
normal:{
show:true,
position:'end',
formatter:'线'
}
},
data: [{
yAxis: 350,
}]
},
data: [],
},
{
name:'趋势线',
type:'line',
//data:[0],
markLine: {
name:'aa1',
data: [[
{name: '标线1起点', value: 0, coord:['100',700]},
{name: '标线1终点',value: 0, coord:['700',20]}
]]
}
}
]
};
myChart14.setOption(option14);
</script>
</body>
</html>
2、双y坐标带增量的柱状图+折线图（如下图)
代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div id="pic4" style="width: 1000px;height:400px;"></div>
<script src="js/echarts.js"></script>
<script>
var myChart = echarts.init(document.getElementById('pic4'));
option = {
title: {
},
tooltip: {
trigger: 'axis'
},
legend: {
data:['需方','供方','需方平均','供方平均','结算平均价差','我方申报均价','我方成交申报'],
bottom:'bottom'
},
toolbox: {
show: true,
feature: {
dataView: {readOnly: false},
restore: {},
saveAsImage: {}
}
},
dataZoom: {
show: false,
start: 0,
end: 100
},
toolbox:{
show:false,
},
xAxis: [
{
type: 'category',
boundaryGap: true,
data: []
},
{
type: 'category',
boundaryGap: true,
data:['需方','供方','需方平均','供方平均','结算平均价差','我方申报均价','我方成交申报'],
}
],
yAxis: [
{
type: 'value',
scale: true,
boundaryGap: [0.2, 0.2]
},
{
type: 'value',
scale: true,
boundaryGap: [0.2, 0.2]
}
],
series: [
{
name: '辅助',
type: 'bar',
stack: '总量',
barWidth: '50%',
itemStyle: {
normal: {
barBorderColor: 'rgba(0,0,0,0)',
color: 'rgba(0,0,0,0)'
},
emphasis: {
barBorderColor: 'rgba(0,0,0,0)',
color: 'rgba(0,0,0,0)'
}
},
data: [-12,-13,-14,-15,-16,-17,-18]
},
{
name: '需方',
type: 'bar',
stack: '总量',
color:['#ecc29c'],
barWidth: '50%',
data:[-11,-12,-13,-14,-15,-16,-17]
},
{
name: '供方辅助',
type: 'bar',
stack: '总量1',
clickable : true,
itemStyle: {
normal: {
barBorderColor: 'rgba(0,0,0,0)',
color: 'rgba(0,0,0,0)'
},
emphasis: {
barBorderColor: 'rgba(0,0,0,0)',
color: 'rgba(0,0,0,0)'
}
},
data: [-4,-5,-6,-7,-8,-9,-10]
},
{
name:'供方',
type:'bar',
color:["#8fb3e7"],
stack: '总量1',
xAxisIndex: 1,
yAxisIndex: 1,
data:[-5,-6,-7,-8,-9,-1,-11]
},
{
name:'供方平均',
type:'line',
data:[-8,-11,-12,-13,-14,-15,-16]
},
{
name:'结算平均价差',
type:'line',
data:[-8,-9,-11,-12,-13,-14,-45]
}
]
};
myChart.setOption(option);
</script>
</body>
</html>
3、一个div中放多个饼图
代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
#pic{
width:100%;
height:800px;
}
</style>
</head>
<body>
<div id="pic"></div>
<script src="js/echarts.js"></script>
<script>
var mychart = echarts.init(document.getElementById('pic'))
option = {
title : {
text: '',
subtext: '',
x:'center'
},
tooltip : {
trigger: 'item',
formatter: "{a} {b} :{d}%",
textStyle: {
fontSize:14
}
},
legend: {
orient: 'vertical',
left: 'left',
data: ['优秀','通过','建议修改']
},
toolbox: {
show: true,
orient: 'vertical',
left: 'right',
top: 'center',
feature: {
dataView: {readOnly: false},
restore: {},
saveAsImage: {}
}
},
grid: [
{x: '0%',y: '25%', width: '100%', height: '40%'},
],
xAxis: [
{
type: 'category',
axisTick: {
alignWithLabel: true
},
axisLabel:{
interval:0 //设置间隔，0的时候全部显示
}, data: ['合同数量（个）','合同电量（万千瓦时）','合同总价（元）']
},
],
yAxis: [
{gridIndex: 0,name:'年级',show:false},
],
series : [
{
title:'aaa',
name: '合同数量（个）',
type: 'pie',
//roseType:'radius',
radius : '33%',
center: ['16.5%', '31%'],
data:[
{value:5, name:'优秀'},
{value:32-5-14, name:'通过'},
{value:14, name:'建议修改'}
],
label: {

formatter: '{c}份',
textStyle: {
color: '#ffffff',
fontSize: 14
}
}
},
itemStyle: {
emphasis: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
},
{
name: '合同电量（万千瓦时）',
type: 'pie',
radius : '33%',
center: ['50%', '31%'],
data:[
{value:23, name:'优秀'},
{value:46-23, name:'通过'},
{value:13, name:'建议修改'},
/*{value:335, name:'3'},
{value:1548, name:'4'}*/
],
label: {
normal: {
position: 'inner',
formatter: '{c}份',
offset: [,100],
textStyle: {
color: '#ffffff',
fontSize: 14
}
}
},
itemStyle: {
emphasis: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
},
{
name: '合同总价（元）',
type: 'pie',
//roseType:'radius',
radius : '33%',
center: ['83.5%', '31%'],
data:[
{value:0, name:'优秀'},
{value:0, name:'通过'},
{value:0, name:'建议修改'},
],
label: {
normal: {
position: 'inner',
formatter: '{c}份',
