how to set start value as "0" in chartjs?

When using Chart.js, ensuring that the chart starts at zero can improve data readability, especially when presenting data that requires comparison starting from zero. To set the Y-axis to start at zero, you can specify the beginAtZero option for the Y-axis in your chart configuration. This ensures that the Y-axis begins at 0 regardless of the minimum value of the data points. Here is a basic example demonstrating how to set the Y-axis to start at zero in a bar chart: javascript var ctx = document.getElementById('myChart').getContext('2d'); var myChart = new Chart(ctx, { type: 'bar', data: { labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'], datasets: [{ label: '# of Votes', data: [12, 19, 3, 5, 2, 3], backgroundColor: [ 'rgba(255, 99, 132, 0.2)', 'rgba(54, 162, 235, 0.2)', 'rgba(255, 206, 86, 0.2)', 'rgba(75, 192, 192, 0.2)', 'rgba(153, 102, 255, 0.2)', 'rgba(255, 159, 64, 0.2)' ], borderColor: [ 'rgba(255, 99, 132, 1)', 'rgba(54, 162, 235, 1)', 'rgba(255, 206, 86, 1)', 'rgba(75, 192, 192, 1)', 'rgba(153, 102, 255, 1)', 'rgba(255, 159, 64, 1)' ], borderWidth: 1 }] }, options: { scales: { y: { beginAtZero: true // Set the Y-axis to start at zero } } } }); In this code, options.scales.y.beginAtZero: true is the key configuration that instructs Chart.js to render the Y-axis starting from 0 without considering the minimum value of the dataset. This setting is crucial for ensuring the accuracy and readability of the chart, especially when the data you display includes zero or negative values.
