highcharts 柱状图问题
用highcharts 做柱状图时，要在每个柱状图中间显示柱状图的名称，也就是显示series.data.name的值。该怎么做？
代码如下：
$(function () {
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'subsystem hot lun / 24h'
},
xAxis: {
categories: [
'CX3-80 hot lun',
'CX700 hot lun',
'VX500 hot lun',
],
labels: {
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
},
formatter: function(){
return this.value;
}
},
yAxis: {
min: 0,
title: {
text: 'AVG IOps (io/s)'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
tooltip: {
headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
'<td style="padding:0"><b>{point.y:.1f} mm</b></td></tr>',
footerFormat: '</table>',
shared: true,
useHTML: true
},
plotOptions: {
column: {
cursor: 'pointer',
pointPadding: 0,
borderWidth: 0,
dataLabels: {
enabled: true,
style: {
fontWeight: 'bold'
},
formatter: function() {
return this.y;
}
}
}
},
series: [{
name: 'TOP 1',
data:[{
name:'point 1',
y:149
},{
name:'point 2',
y:133.5
},{
name:'point 3',
y:122.4
}]
}, {
name: 'TOP 2',
data: [{
name:'point 4',
y:112
},{
name:'point 5',
y:90
},{
name:'point 6',
y:102
}]
}, {
name: 'TOP 3',
data: [{
name:'point 7',
y:50
},{
name:'point 8',
y:70
},{
name:'point 9',
y:40
}]
}]
});
});求大神指教 JavaScript highcharts --------------------编程问答--------------------
--------------------编程问答--------------------
formatter: function() {return this.name + ':' +this.y;
}
--------------------编程问答--------------------
是在哪里加？
plotOptions: {
column: {
cursor: 'pointer',
pointPadding: 0,
borderWidth: 0,
dataLabels: {
enabled: true,
style: {
fontWeight: 'bold'
},
formatter: function() {
return this.name+":"+this.y;
}
}
}
},加了以后都是this.name都显示undefined. --------------------编程问答-------------------- plotOptions: {
column: {
cursor: 'pointer',
pointPadding: 0,
borderWidth: 0,
dataLabels: {
enabled: true,
style: {
fontWeight: 'bold'
},
formatter: function() {
<span style="color: #FF0000;"> return this.name+":"+this.y;</span>
}
}
}
},
在plotOptions加了以后都是this.name都显示undefined. --------------------编程问答-------------------- plotOptions: {
column: {
cursor: 'pointer',
pointPadding: 0,
borderWidth: 0,
dataLabels: {
enabled: true,
style: {
fontWeight: 'bold'
},
formatter: function() {
return this.name+":"+this.y;
}
}
}
},
在plotOptions加了以后都是this.name都显示undefined. --------------------编程问答-------------------- 建议看着demo里面的格式，生成数据，改写js
补充：Java , Web 开发
