How to create semicircle progress using ProgressBar.js

July 09, 2023



Here I have used ProgressBar.js to create semicircle progress element.

Download the required file from this link - https://kimmobrunfeldt.github.io/progressbar.js/

1. Add the progressbar.min.js file to your head section of html file.
<script src="progressbar.min.js"></script>

2. Put the following code in body section in html 
<div id="halfcircle">
</div>

3. Then put the below JavaScript code in body section of your html project file -
<script>
        var a = 65.
        var out = a / 100.
        var bar = new ProgressBar.SemiCircle(halfcircle, {
            strokeWidth: 6,
            color: '#FFEA82',
            trailColor: '#eee',
            trailWidth: 1,
            easing: 'easeInOut',
            duration: 1400,
            svgStyle: null,
            text: {
                value: '',
                alignToBottom: false
            },
            from: {
                color: '#FFEA82'
            },
            to: {
                color: '#ED6A5A'
            },
            // Set default step function for all animate calls
            step: (state, bar) => {
                bar.path.setAttribute('stroke', state.color);
                var value = Math.round(bar.value() * 100);
                if (value === 0) {
                    bar.setText('');
                } else {
                    bar.setText(value);
                }
                bar.text.style.color = state.color;
            }
        });
        bar.text.style.fontSize = '1.5rem';
        bar.animate(out); // Number from 0.0 to 1.0
    </script>

4. Then add this CSS property to your CSS file - 
#halfcircle {
  margin: 20px;
  width: 200px;
  height: 100px;
}
