[Chartjs]-Set Global Config on Angular Charts Not Working

The way you setting beginAtzero property its wrong. Because when you configure global setting for chart scale, there is no option for setting it for xAxes or yAxes.
Try the below code for setting beginAtZero

ChartJsProvider.setOptions({
    scale : {
        ticks : {
            beginAtZero : true
        }
    }
});
