对数据进行正常排序(前后端均可), 然后将json数组里面的每一个json对象作为一个序列, Sorted the data first! then
set each json object as a serial.
```
forEach(dataBySite[site], (json) => {
dataset.push({ source: [json] })
series.push({
name: json['NCCAT'],
type: 'bar',
datasetIndex: dataset.length - 1,
xAxisIndex: 0,
yAxisIndex: 0,
label: {
show: true,
position: 'bottom',
formatter: '{@PCT}'
},
emphasis: {
focus: 'series'
},
tooltip: {
trigger: 'item',
formatter: multiLineFormatter
},
encode: {
x: 'target',
y: 'PCT'
},
stack: site,
label: {
show: true,
verticalAlign: 'middle',
position: '',
formatter: '{@catCnt}'
}
})
})
```
关键代码core code:
此例中原始数据进行了分组，按分组进行堆叠。
```
forEach(dataBySite[site], (json) => {
dataset.push({ source: [json] })
series.push({
name: json['NCCAT'],
stack: site,
```
效果如下Result as bellow：
