How to insert values in the gauge chart

I'm using widget gauger and would like to insert my own value

For example, the maximum value would be 200 and minimum 0

The value to set would be 175

How do I enter values in gauge?

How to understand this code?

function init_gauge() {
            if ("undefined" != typeof Gauge) {
                console.log("init_gauge [" + $(".gauge-chart").length + "]"), console.log("init_gauge");
                var a = {
                    lines: 12,
                    angle: 0,
                    lineWidth: .4,
                    pointer: {
                        length: .75,
                        strokeWidth: .042,
                        color: "#1D212A"
                    },
                    limitMax: "false",
                    colorStart: "#1ABC9C",
                    colorStop: "#1ABC9C",
                    strokeColor: "#F0F3F3",
                    generateGradient: !0
                };
                if ($("#chart_gauge_01").length)
                    var b = document.getElementById("chart_gauge_01"),
                    c = new Gauge(b).setOptions(a);

                if ($("#gauge-text").length &&
                      (c.maxValue = 6e3, c.animationSpeed = 32, c.set(1690), c.setTextField(document.getElementById("gauge-text"))),
                      $("#chart_gauge_02").length
                   )

                    var d = document.getElementById("chart_gauge_02"),
                    e = new Gauge(d).setOptions(a);

                $("#gauge-text2").length && (e.maxValue = 9e3, e.animationSpeed = 32, e.set(2400), e.setTextField(document.getElementById("gauge-text2")))
            }
        }

What does this 6a3 mean? I've changed a few things, but I still do not understand this right code.
