ViewsHow to correctly transform data for a stack chart chartJS (data transformation)?
There is data that comes from the server
const groupedChartData = [
{
duration: '00:00:10',
stats: [
{color: 'red', reason: 'yes', value: 11},
{color: 'green', reason: 'no', value: 33},
]
},
{
duration: '00:01:00',
stats: [
{color: 'black', reason: 'call back', value: 32},
{color: 'green', reason: 'no', value: 77},
]
},
{
duration: '00:10:00',
stats: [
{color: 'red', reason: 'yes', value: 14},
]
}
]
Based on the data from the server, you need to generate the following object for correct display
data on the chart, that is, each first value from the stats object in groupedChartData must correspond
to the first in the next object, the second to the second, and
exprected result
let result = [
{
data: [11, 32, 14],
backgroundColor: ['red', 'black', 'red']
},
{
data: [33,77],
backgroundColor: ['green', 'green']
}
]

I hope the commented code below helps you:
const result = []
groupedChartData.forEach(el=>{
el.stats.forEach((el, ind)=>{
//checking if position is null
if(result[ind] == null){
result[ind] = {data:[], backgroundColor: []}
}
//pushing new values to the new array
result[ind].data.push(el.value)
result[ind].backgroundColor.push(el.color)
})
})
console.log(result)
