Create Dynamic Half Circular Progress Bar With HTML 5 CSS 3 - Create Gauge Chart In HTML 5
Recently in one of my project there was a requirement to create half circle gauge chart to show progress of some actions. Something like below image
So first of all I decided to use some charts library to create UI like this but since this was mobile application I do not find any suitable chart library. So I decided to build UI from scratch. So here is the step by step guide.
So as you can see we are setting border with to container width and make it fit inside container and setting inner circle width to bit less than border width to create circular progress bar. Now we calculate transform degrees to set up liner gradient to show progress.
var degree = (180 * Number(count)) / (Number(total));
