Changes

The following changes were made

• only a parameter was added which is created by some internal function call

With this change it is possible to set the used starcaptionClass on percentage.

$this->pluginOptions['starCaptionClasses'] = new JsExpression("function(val, percentage){
            if (percentage !== undefined) {
                if (percentage <= 20) {
                     return 'label label-danger';
                }
                else if (percentage <= 40) {
                    return 'label label-warning';
                }
                else if (percentage <= 60) {
                    return 'label label-info';
                }
                else if (percentage <= 80) {
                    return 'label label-primary';
                }
                else { // if (percentage <= 100)
                    return 'label label-success';
                }
            }
        }");

So it is independent from the min, max and stars value.
