Chartjs-Chartjs, scatter with For-Loop

Usually I set up my objects and arrays how I need them at first and then fill them with data.

Set it up:

var chartData = {
  datasets: [{
    label: 'Test',
    data: []
  }]
}

Fill it with data:

for (var i = 0; i < yWerte.length; i++) {
  chartData.datasets[0].data.push(
    {
      x: xWerte[i], // You don't need "xWerte", you can simply use "i" when it's always the increment
      y: yWerte[i]
    }    
  )
}

You don’t need your c to save your data, you can just use it like I did. But if you want c you can save the result of the for-loop in the empty array c and then use chartData.datasets[0].data = c.
