Problem with the minimum value of a Semi-circular progress bar


Posted by milan at 22:25 on Wednesday 11th October 2023 [link]
Hello,

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

Hmm, I thought the SCP handled negative values - evidently not! I'll fix it for you and get back to you (later on today hopefully).

Cheers.

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();
