[Solved]-Searching for JS based (Highcharts, AnyChart, etc) thermometer or vertical linear gauge with multiple pointers-Highcharts

You can create that type of chart by using Highcharts. Use for example column series type and each segment can be a visible part of the column. To add the gradient colors easily, use color axis with stops. And finally, to add the pointers, use SVG.Renderer class.

    colorAxis: {
        visible: false,
        stops: [
            [0, '#00bfff'],
            [0.3, '#007bff'],
            [0.35, '#0dc200'],
            [0.5, '#bbff99'],
            [0.55, '#ff8400'],
            [0.9, '#ff0000']
        ],
    },
    series: [{
        pointWidth: 40,
        type: 'column',
        borderWidth: 0,
        threshold: 15,
        data: [
            [0, 85],
            [0, 80],
            [0, 75],
            [0, 70],
            [0, 65],
            [0, 60],
            [0, 55],
            [0, 50],
            [0, 45],
            [0, 40],
            [0, 35],
            [0, 30],
            [0, 25],
            [0, 20]
        ]
    }]
