seek for help for grouping them. I got an input with this.
[
{
"apiName": "APISend",
"channel": "Mozilla",
"noa": 3
},
{
"apiName": "API",
"channel": "PostMan",
"noa": 1
},
{
"apiName": "APICall",
"channel": "PostMan",
"noa": 4
},
{
"apiName": "API",
"channel": "Mozilla",
"noa": 2
}
]
How can I group them as channel and then by apiName? My final output should be like this:
labels = ["Mozilla","PostMan"]
datasets = [{label:"APISend", data:[3,0]} , {label:"API",data:[2,1], {label:"APICall",data:[0,4]]}
just like this, you can have a try.
const arr = [{'apiName': 'APISend', 'channel': 'Mozilla', 'noa': 3}, {'apiName': 'API', 'channel': 'PostMan', 'noa': 1}, {'apiName': 'APICall', 'channel': 'PostMan', 'noa': 4}, {'apiName': 'API', 'channel': 'Mozilla', 'noa': 2}]
function transtArr(data){
let labels = []
let datasets = []
data.forEach((value) => {
labels.push(value.channel)
let _indexNum = datasets.findIndex(x => x.label === value.apiName)
if(_indexNum > -1){
datasets[_indexNum].data.push(value.noa)
} else {
let _obj = {label: value.apiName, data: [value.noa]}
datasets.push(_obj)
}
})
return {labels: [...new Set(labels)], datasets}
}
