1、问题背景
统一一周内植树的数量，利用柱状图来实现
2、实现源码
（1）X轴从零刻度开始
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>echarts-X轴不从0刻度开始</title>
<link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png">

<script type="text/javascript" src="../js/echarts-2.2.7/doc/example/www2/js/echarts-all.js" ></script>
<style>
body,html{
99%;
height: 99%;
font-family: "微软雅黑";
font-size: 12px;
}
#bar{
100%;
height: 100%;
}
</style>
<script>
$(function(){
var chart = document.getElementById('bar');
var echart = echarts.init(chart);
var option = {
title: {
text: ''
},
tooltip: {
trigger: 'axis'
},
legend: {
data:['植树数量']
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
toolbox: {
feature: {
saveAsImage: {}
}
},
xAxis: {
type: 'category',
boundaryGap: false,
data: ['周一','周二','周三','周四','周五','周六','周日']
},
yAxis: {
type: 'value'
},
series: [
{
name:'植树数量',
type:'bar',
stack: '植树数量',
data:[34, 12, 56, 27, 42, 87, 62]
}
]
};
echart.setOption(option);
});
</script>
</head>
<body>
<div id="bar"></div>
</body>
</html>
（2）X轴不从零刻度开始
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>echarts-X轴不从0刻度开始</title>
<link rel="shortcut icon" href="../js/echarts-2.2.7/doc/asset/ico/favicon.png">
<script type="text/javascript" src="../js/echarts-2.2.7/doc/asset/js/jquery.min.js" ></script>
<script type="text/javascript" src="../js/echarts-2.2.7/doc/example/www2/js/echarts-all.js" ></script>
<style>
body,html{
99%;
height: 99%;
font-family: "微软雅黑";
font-size: 12px;
}
#bar{
100%;
height: 100%;
}
</style>
<script>
$(function(){
var chart = document.getElementById('bar');
var echart = echarts.init(chart);
var option = {
title: {
text: ''
},
tooltip: {
trigger: 'axis'
},
legend: {
data:['植树数量']
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
toolbox: {
feature: {
saveAsImage: {}
}
},
xAxis: {
type: 'category',
boundaryGap: true,
data: ['周一','周二','周三','周四','周五','周六','周日']
},
yAxis: {
type: 'value'
},
series: [
{
name:'植树数量',
type:'bar',
stack: '植树数量',
data:[34, 12, 56, 27, 42, 87, 62]
}
]
};
echart.setOption(option);
});
</script>
</head>
<body>
<div id="bar"></div>
</body>
</html>
3、实现结果
（1）X轴从零刻度开始
（2）X轴不从零刻度开始
4、问题说明
在xAxis中的boundaryGap属性，设置为false代表是零刻度开始，设置为true代表离零刻度间隔一段距离
