I have a simple pie chart (see code below) with two data columns column1=79.48 and column2=20.52, however, when the chart is rendered, it only displays a single slice of 100.00%. I am using a datatable with two fields. Am I just not referencing or assigning something properly?

BorderWidth="1px" ChartType="PieChart3D" EmptyChartText="Data Not Available. Please call UltraChart.Data.DataBind() after setting valid Data.DataSource"
