Hey, thanks for this plugin!

In some cases the line seems to be rendered incorrectly:

I also ran into a similar problem when multiple data points had the same value on the x-axis: the line would be shorter and not span the entire canvas but stop in the middle of the chart. Would it be possible to render the line from the first to the last datapoint, so that it always spans the whole canvas?

Thank you!

Data

// [Date, number]
const data = [
  [new Date('2020-01-01'), 42],
  [new Date('2020-01-02'), 87],
  [new Date('2020-01-03'), 27],
  [new Date('2020-01-04'), 13],
  [new Date('2020-01-05'), 7],
  [new Date('2020-01-06'), 33],
  [new Date('2020-01-07'), 66],
];

Scale Option

scales: {
  xAxes: [
    {
      type: 'time',
    },
  ],
}

It only works when I remove the type: 'time' option from the xAxis. (same data)
Otherwise with time type, the line is just not drawing without errors.

This plugin is not working at v2.9.4.
