Highcharts not creating correct amount of labels (steps) in xAxis only first and last labels

Question

Here is a jsFiddle to my issue:

Highcharts.chart('container', {
    
    xAxis: {
        categories: [full arrray in fiddle],
        labels: {
            step: 1
        }
    },

    series: [{
        data: Array.from(Array(690).keys())
    }]
});

The chart seems to only take the first and last label, why is this?

Answer 1

I think the reason this did not work is because of the amount of time needed to process each category which are long dates, this is basically what is written here The solution was just to use xAxis.tickInterval instead, with the same interval as before.
