✅
just map the key
and values
to appropriate arrays and consume them as datasets
and labels
.
var data = {
"count": 2,
"result": {
"2020-01-22": {
"confirmed": 12,
"deaths": 5,
"recovered": 4
},
"2020-01-23": {
"confirmed": 20,
"deaths": 3,
"recovered": 2
}
}
}
var dates = Object.keys(data["result"]).map(x => x);
var confirm = Object.values(data.result).map(x => x.confirmed);
var deaths = Object.values(data.result).map(x => x.deaths);
var recovered = Object.values(data.result).map(x => x.recovered);
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: dates,
datasets: [{
label: 'confirmed',
data: confirm,
backgroundColor: 'rgba(255, 99, 132, 0.2)',
borderColor: 'rgba(255, 99, 132, 1)',

},
{

}, {

data: recovered,
