Hello, If I assign a minimum value other than 0 to a semicircular progress bar, entire bar disappears. Any help regarding this? Thanks!

License

RGraph can be used for free under the GPL or if that doesn't suit your situation there's an inexpensive (£129) commercial license available.

OK I've updated the Semi-circular progress source file and you can get it here from GitHub:

https://raw.githubusercontent.com/heyesr/rgraph/main/libraries/RGraph.semicircularprogress.js

And here's some example source code:

new RGraph.SemiCircularProgress({
    id: 'cvs',
    min: -100,
    max: 100,
    value: -50,
    options: {
        radius: '-50',
        width: 50,
        labelsCenterSize: 120,
        labelsCenterUnitsPost: 'k',
        labelsCenterOffsety: 20,
        colorsStroke: 'transparent',
        backgroundGrid: true,
        scale: true,
        scaleLabelsCount: 20
    }
}).grow();
