To sort data from highest to lowest in Chart.js, you can use the sort method in JavaScript before rendering the chart. Here is an example of how you can achieve this:

  1. First, make sure you have included the Chart.js library in your HTML file:
1
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>


  1. Next, define your data array with values that you want to sort:
1
const data = [10, 5, 20, 15, 25];


  1. Sort the data array from highest to lowest using the sort method:
1
data.sort((a, b) => b - a);


  1. Once the data is sorted, create a Chart.js chart with the sorted data:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
const ctx = document.getElementById('myChart').getContext('2d');

const myChart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ['A', 'B', 'C', 'D', 'E'],
        datasets: [{
            label: 'Data',
            data: data,
            backgroundColor: 'blue',
        }]
    },
    options: {}
});


By sorting the data array before rendering the chart, you will display the data in descending order from highest to lowest.
