xValue for point annotations not recognizing x-axis scale

[gespinha]

Hi everyone,

I've got a line chart with the following dataset:

datasets: [
  {
    data: [
      { "value": 1, "label": 595900800000 },
      { "value": 1, "label": 597456000000 },
      { "value": 3, "label": 597542400000 },
      { "value": 5, "label": 599184000000 },
      { "value": 10, "label": 600652800000 },
      { "value": 12, "label": 603331200000 },
      { "value": 12, "label": 603590400000 },
      { "value": 17, "label": 606009600000 },
    ]
  }
]

and these options:

const options = {
  responsive: true,
  maintainAspectRatio: false,
  plugins: {
    annotation: {
      annotations: {
        point1: {
          type: 'point',
          xValue: 600652800000,
          yValue: 10,
          backgroundColor: '#f00'
        }
      }
    }
  }
}

As you can see the annotation point's xValue is set to 600652800000, but the point doesn't show in the chart. But if I change that value to 5 it works. The xValue is supposed to be a date and I want to be able to place my points in any date I want, even if it falls between two dates in the chart.

How can I have the xValue be a value within the range of my dataset labels?

Thanks!
