Customize the label display

[kkliuxu]

This is pretty cool Gauge Library., But I find that, if I want to customized or so call format the label. I can not. this is how I want to showing the label

however, I only can show the value and can not format it.

Could you improve it in the next version? Thanks.

Agree that label formatting is not that great.... The quickest way to improve it is to make the modifications you need yourself, though. Feel free to submit a pull request.

What we could do is to open up for a user-given value formatter function. That means that you as a user can override the standard value formatting function inside gauge.js like this:

function myValueFormat(value, digits) {
  return value.toFixed(digits) + "%";
}

// Provide access to it alongside the other options
var opts = {
  // ...
  valueFormat: myValueFormat
};
var target = document.getElementById('foo'); // your canvas element
var gauge = new Gauge(target).setOptions(opts);

Something like that, maybe?

I'm in need of custom label strings too.

I also need custom labels based on the value. The proposed solution by kplindegaard looks promising! Any chance of integrating this?
