React line chart with hours removed

Question

I want to remove every three hours from the bottom of the rope chart. I'm using react-chart-js2. I'm using the .map function to display these numbers. Is it possible to display only every three of them? Chart

Here is the code that displays the hours:

const data = {
       labels: chart.prices?.map(x => moment(x[0]).format('h:mm a')),
        datasets: [{
            data: chart.prices?.map(x => x[1]),
            backgroundColor: '#ffffff00',
            borderColor: 'rgb(79 70 229)',
            borderWidth: '2',
            pointBorderColor: '#ffffff00',
            tension: 0.4,
            fill: {
                target: "origin", // 3. Set the fill options
                above: "rgba(79, 70, 229, 0.0625)"
            }
        }]
      }

I want only every third number to be displayed

Answer 1

Replace every third item with an empty string.

let hours = chart.prices?.map(x => moment(x[0]).format('h:mm a'));

for (let i=0; i<=hours.length; i++) {
  if((i+1) % 3 == 0){
        hours[i] = "";
  }
}

Then in chart.js:

labels: hours,
