To update a Chart.js chart using JavaScript, you can use the following steps:

  1. Get a reference to the chart object: var chart = new Chart(ctx, {...}); // assuming ctx is the canvas context for the chart
  2. Update the data or options of the chart object as needed: chart.data.datasets[0].data = newDataArray; // update the data values for the first dataset chart.options.title.text = 'New Chart Title'; // update the title of the chart
  3. Call the update method on the chart object to apply the changes: chart.update();


By following these steps, you can easily update a Chart.js chart dynamically using JavaScript.
