When the current culture is set to french the piechart doesn't render

[JeanVACCA]

The issue come from the double/decimal encoding of the javascript string : when the culture is french, the decimal separator is "," so it generate a bug.

I suggest you to use Invariant Culture in the ToString function if possible.

Could you share more details on the bug? Like what you are inputting and the screenshot of the occurring bug

Here is the code to reproduce the bug

public ActionResult Test()
        {
        string[] colors = new string[]{
            "rgb(255, 99, 132)",
            "rgb(255, 159, 64)",
            "rgb(255, 205, 86)",
            "rgb(78, 216, 218)",
            "rgb(54, 162, 235)",
            "rgb(192, 77, 216)",
            "rgb(201, 203, 207)"
        };
            string[] fakeLabels = new string[] { "Item1", "Item2", "Item3" };
            int[] fakeDatas = new int[] { 5, 3, 2 };
            var testPieChart = new ChartTypePie()
            {
                Data = new PieData()
                {
                    Labels = fakeLabels,
                    Datasets = new PieDataSets[] { 
                        new PieDataSets(){
                            LinearData = fakeDatas,
                            BackgroundColor = colors
                        }
                    }
                },
                Options = new PieOptions(){
                }
            };
            ViewBag.PieChart = new MvcHtmlString(testPieChart.Draw("test"));
            return View();
        }

The generated json code is followed

<script>
var test_ctx = document.getElementById('test').getContext('2d');
var test_Chart = new Chart(test_ctx, {
type:'pie',
data:{
    datasets:[{
        backgroundColor:['rgb(255, 99, 132)','rgb(255, 159, 64)','rgb(255, 205, 86)','rgb(78, 216, 218)','rgb(54, 162, 235)','rgb(192, 77, 216)','rgb(201, 203, 207)'],
        data:[5,3,2],
        }],
    labels:['Item1','Item2','Item3'],
},
options:{
    cutoutPercentage:0,
    rotation:-1,5707963267949,
    circumference:6,28318530717959,
    events:['mousemove','mouseout','click','touchend','touchmove','touchstart'],
},

});
</script>

As you can see the value for rotation options and circumference contains comma instead of dot (due to the current thread culture)
