Pushing/refreshing data

[DuncanTLaw]

I have some data:
data: number[] = [100, 90, 87, 60]
and my chart is initialised as such:

this.myChart = new Chart(
      document.getElementById('htmlChart') as HTMLCanvasElement,
      {
        type: 'line',
        data: {
          datasets: [
            {
              label: 'my data',
              data: this.data,
            },
          ],
        },
...

What would be the best way to edit the data? Say I want to push newData = 70 into the chart, would I do it through

 this.data.push(newData)

or

this.myChart.data.datasets[0].data.push(newData)

What about if I want to replace all the data in data with a new number array? What steps do I take and do I have to use any of the built-in clear() or update() etc. methods?

If you want an entirely new array you can override the old one and calling update method
