Using JSON Values in JavaScript

[{"Januari":"0","Februari":"0","Maret":"0","April":"0","Mei":"7","Juni":"0","Juli":"0","Agustus":"0","September":"0","Oktober":"0","November":"0","Desember":"0"}]

var ctx = document.getElementById("myAreaChart");
var myLineChart = new Chart(ctx, {
    type: 'line',
    data: {
        datasets: [{
           label: "Visitor",
           data: [0, 0, 0, 0, 7, 0, 0, 0, 0, 0, 0, 0],  //<-- place values here
    }],
},

Answer №1

By utilizing the Object.values method along with Array.map, you can extract values and convert them to integers in the following manner:

var json = [{"Januari":"0","Februari":"0","Maret":"0","April":"0","Mei":"7","Juni":"0","Juli":"0","Agustus":"0","September":"0","Oktober":"0","November":"0","Desember":"0"}];
var numbers = Object.values(json[0]).map(s => parseInt(s, 10));

Lastly, make sure to update your example like so:

data: numbers,
