Populate JavaScript Array from JSON Format

Question

Hi I have JSON data that looks like this:

[
  {"Mean of Arrivals for each hour":
     {"03-04":-35.62,"04-05":-3.62,"05-06":-3.7}
  }
]

I want to push it to an array, and have the array look like this:

[
{x: 03-04 y: -35.62},
{x: 04-05, y: -3.62},
{x: 05-06, y: -3.7}
]

Right now, it looks like the array below, and I don't know how to format it to look like above. Below is also the code I am using to populate the array. Would love some help on how to format the array.

[
x: {03-04: -35.62, 04-05: -3.62, 05-06: -3.7},
y: {03-04: -35.62, 04-05: -3.62, 05-06: -3.7}
]

var dataPoints = []; // final array with data

var chartData = new google.visualization.DataTable();
chartData.addColumn('string', 'Stunde');
chartData.addColumn('number', 'Ankunft');

function addData(data) {
    for (var i = 0; i < data.length - 1; i++) {
        dataPoints.push({
          x: data[i]["Mean of Arrivals for each hour"],
          y: data[i]["Mean of Arrivals for each hour"]
         });
    }

    dataPoints.forEach(function (row) {
        chartData.addRow([row.x, row.y]);
    });

    console.log(dataPoints);
    var chart = new google.charts.Bar(document.getElementById('plot3'));
    chart.draw(chartData, google.charts.Bar.convertOptions(options));
};

$.getJSON(url, addData);

Use a for...in loop to loop through the properties, construct the JSON and push to the array:

const data = [
  {"Mean of Arrivals for each hour":
     {"03-04":-35.62,"04-05":-3.62,"05-06":-3.7}
  }
]
const result = [], r = data[0]["Mean of Arrivals for each hour"];

for(const key in r) result.push({x: key, y: r[key]})

console.log(result);
