Histogram

Histogram type charts can provide a visual display of large amounts of data that are difficult to understand in a tabular or spreadsheet form. To render a histogram chart, use series type as Histogram and inject HistogramSeries module using Chart.Inject(HistogramSeries) method.

var chartData = [];
     var points = [5.250, 7.750, 0, 8.275, 9.750, 7.750, 8.275, 6.250, 5.750,

    points.map(function (value) {
       chartData.push({
            y: value
        });
