Stacked scatter graph

I’m trying to stacked my scatter graph with the option stacked: true, but when I do that my graph just disappear. I use the version 2.7.2 of chartjs.

'use strict';

function filledLine(input_data, html_markup, extra_config) {
  var scatterChartData = {
    datasets: input_data.datasets,
  };

  window.myScatter = Chart.Scatter(document.getElementById(html_markup), {
    data: scatterChartData,
    options: {
      title: {
        display: true,
        text: 'Chart.js Scatter Chart',
      },
      scales: {
        xAxes: [
          {
            position: 'bottom',
            scaleLabel: {
              display: true,
              labelString: 'x axis',
            },
          },
        ],
        yAxes: [
          {
            stacked: true,
            position: 'left',
            scaleLabel: {
              display: true,
              labelString: 'y axis',
            },
          },
        ],
      },
    },
  });
}

I would expect it should assuming a line chart is supposed to stack. They’re basically the same thing except scatter doesn’t show the line with the points. And my assumption is that you should be able to stack a line chart

I got it working, opening a PR and we can discuss
