LineChart not displaying last 'stroke' in IE 10

IE 10 : I can not get the last "stroke" in line chart, if I do the same thing in pie chart, it renders as expected.

Firefox : Both are working as expected.

Screen shot : IE 10& fifrefox 23.0.1

Below is the code snippet :

aspx

<div id="chart"><ajaxToolkit:ToolkitScriptManager runat="server"></ajaxToolkit:ToolkitScriptManager><ajaxToolkit:LineChart ID="LineChart1" runat="server" ChartHeight="300" ChartWidth="900"
			ChartType="Stacked" ChartTitleColor="#0E426C" CategoryAxisLineColor="#D08AD9"
			ValueAxisLineColor="#D08AD9" BaseLineColor="#A156AB"></ajaxToolkit:LineChart><ajaxToolkit:PieChart ID="PieChart1" runat="server" ChartHeight="300" ChartWidth="300"
			ChartType="Column" ChartTitleColor="#0E426C"></ajaxToolkit:PieChart></div>

C#

private void PlotCustomerGraph(List<Customer> allCustomers)
		{
			DataTable tblCustomers = new DataTable();
			using (var reader = ObjectReader.Create(allCustomers))
			{
				tblCustomers.Load(reader);
			}
			string[] x = new string[tblCustomers.Rows.Count];
			decimal[] y = new decimal[tblCustomers.Rows.Count];

			for (int i = 0; i < tblCustomers.Rows.Count; i++)
			{
				x[i] = tblCustomers.Rows[i][0].ToString();
				y[i] = decimal.Parse(tblCustomers.Rows[i][2].ToString());

				if (clrStack.Count <= 1)
					clrStack = new Stack<string>(clr);

				PieChart1.PieChartValues.Add(new PieChartValue
				{
					Category = x[i],
					Data = y[i],
					PieChartValueColor = clrStack.Pop()
					});

			}

			LineChartSeries series1 = new LineChartSeries { Data = y };
			series1.Name = "Displaying : Customer Orders";
			LineChart1.Series.Add(series1);
			LineChart1.CategoriesAxis = string.Join(",", x);
			LineChart1.ChartTitle = "Title : Customers Vs. No of Orders";
