C# - MS Chart Control Pie Chart: Remove Unwanted Padding

im trying to create simple pie chart using the MS Chart controls. When my pie chart gets rendered in the browser i get padding around the pie chart that i cant get rid of. i would like the pie chart to sit up against the edge of the image with no padding or margin. in my code below the padding is highlighted in blue. i.e Chart1.BackColor = System.Drawing.Color.Blue;

<script type="text/C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
//Set the chart type
Chart1.Series["Series1"].ChartType = SeriesChartType.Pie;
//add points
Chart1.Series["Series1"].Points.AddY(12);
Chart1.Series["Series1"].Points.AddY(45);
Chart1.Series["Series1"].Points.AddY(67);
//set back color of chart object
Chart1.BackColor = System.Drawing.Color.Blue;
//set back color of chart area
Chart1.ChartAreas["ChartArea1"].BackColor = System.Drawing.Color.Green;
}
</script>
<asp:Chart ID="Chart1" runat="server">
<Series>
<asp:Series Name="Series1" ChartType="Pie">
</asp:Series>
</Series>
<ChartAreas>
<asp:ChartArea Name="ChartArea1">
</asp:ChartArea>
</ChartAreas>
</asp:Chart>
