X axis on scatter plot being generated on highcharts

Question

I am trying to a date-based scatter plot. I mean I want to add dates on the x-axis but it is not adding the dates. In my code, I have added a small portion of the data. The data points is over 500000. What is the most efficient way to do that?

My code:

const series = [{"name":"Page Views","id":"ABC-page_views","data":[["2024-02-26T00:00:00.000Z",1],["2024-02-28T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-28T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-28T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",3],["2024-02-29T00:00:00.000Z",1],["2024-02-29T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",7],["2024-03-01T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-03-01T00:00:00.000Z",1],["2024-02-29T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-28T00:00:00.000Z",1],["2024-02-28T00:00:00.000Z",5],["2024-02-28T00:00:00.000Z",1],["2024-02-28T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-27T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1],["2024-02-26T00:00:00.000Z",1]]}]

How do I make the x-axis display the dates? Also for a large dataset. Not sure how to optimize it.

Answer 1

The issue here is that Highcharts might not recognize the date format in your data. To make it work change your data to this format for example:

 data:[
  [new Date('2017-01-01T00:00:00Z').getTime(), 1],
  [new Date('2017-01-03T00:00:00Z').getTime(), 2]
 ]
