Datasets only support integers

[yannpiot]

Datasets only support integers (linearData). Shouldn't the library support decimal values? @ritesh28393

`public class ChartDataSets
{
public ChartDataSets();

    public string Label { get; set; }
    public string YAxisID { get; set; }
    public string XAxisID { get; set; }
    public int[] LinearData { get; set; }
    public XYdataItem[] XYData { get; set; }
    public XYRdataItem[] XYRData { get; set; }
}`
