BaseGauge

Direct Subclass:

LinearGauge, RadialGauge

Basic abstract BaseGauge class implementing common functionality for different type of gauges.

It should not be instantiated directly but must be extended by a final gauge implementation.

Example:


class MyCoolGauge extends BaseGauge {

    // theses methods below MUST be implemented:

    constructor(options) {
       // ... do something with options
       super(options);
       // ... implement anything else
    }

    draw() {
        // ... some implementation here
        return this;
    }
}
