Migration from 1.0.2
The new gauge uses a viewbox of 100x100 as opposed to previous 1000x1000. All the stroke and font values have to be adjusted accordingly in your CSS. Just divide those by 10

// Standalone
var Gauge = window.Gauge;
// Create a new Gauge
var cpuGauge = Gauge(document.getElementById("cpuSpeed"), {
max: 100,
// custom label renderer
label: function(value) {
return Math.round(value) + "/" + this.max;
},
value: 50,
// Custom dial colors (Optional)
color: function(value) {
if(value < 20) {
return "#5ee432"; // green
}else if(value < 40) {

That's all good, but what about React?
import React, { useEffect, useRef } from "react";
import SvgGauge from "svg-gauge";
const defaultOptions = {
animDuration: 1,
showValue: true,
initialValue: 0,
max: 100
// Put any other defaults you want. e.g. dialStartAngle, dialEndAngle, radius, etc.
};
const Gauge = props => {
const gaugeEl = useRef(null);
const gaugeRef = useRef(null);
useEffect(() => {
if (!gaugeRef.current) {
const options = { ...defaultOptions, ...props };
gaugeRef.current = SvgGauge(gaugeEl.current, options);
gaugeRef.current.setValue(options.initialValue);
}
gaugeRef.current.setValueAnimated(props.value, 1);
}, [props]);
return <div ref={gaugeEl} className="gauge-container" />;
};
export default Gauge;
// to render:
const renderGauge = () => (
<Gauge
value={42}
// any other options you want
/>
);
React w/ TypeScript?
import { useEffect, useRef } from 'react'
import SvgGauge, { GaugeOptions, GaugeInstance } from 'svg-gauge'
const Gauge = ({ value }: Props) => {
const gaugeEl = useRef<HTMLDivElement>(null)
const gaugeRef = useRef<GaugeInstance | null>(null)
useEffect(() => {
if (!gaugeRef.current) {
if (!gaugeEl.current) return
const options: GaugeOptions = { color: value => (value < 30 ? 'green' : 'red') }
gaugeRef.current = SvgGauge(gaugeEl.current, options)
gaugeRef.current?.setValue(1)
}
gaugeRef.current?.setValueAnimated(value, 1)
}, [value])
return (
<div style={{ width: '500px', height: '500px' }}>
<div ref={gaugeEl} />
</div>
)
}
interface Props {
value: number
}
export default Gauge
