i saw this was submitted as a bug with the same source code in the sample ... the problem is fixed now, and will be part of an upcoming hotfix.  if you need a temporary workaround, try setting ColorModel.ModelStyle to something other than CustomSkin.

toggling it doesnt work. basically then it applies the same color to all the bars in the chart. for both 3d and 2d.

try toggling the value of the ColorModel.Skin.ApplyRowWise property. 

This is the code i use to generate the chart. Also iam using 2008 vol1.

In the case of  a 2d stack chart the legend shows Cat A, Cat B....

In the case of a 3d stack chart, the legend only shows "Count". 

Is there any way to get the chart to generate the same legend in the case of a 3d stack chart. 

DataTable table = new DataTable();
        table.Columns.Add(new DataColumn("Name", typeof(String)));
        table.Columns.Add(new DataColumn("Count", typeof(int)));

        table.Rows.Add(new object[ { "Cat A", 10 });
        table.Rows.Add(new object[ { "Cat B", 20 });
        table.Rows.Add(new object[ { "Cat C", 30 });
        table.Rows.Add(new object[ { "Cat D", 40 });
        table.Rows.Add(new object[ { "Cat E", 10 });
        table.Rows.Add(new object[ { "Cat F", 30 });
        table.Rows.Add(new object[ { "Cat G", 20 });



        UltraChart1.ColorModel.Skin.PEs.Add(new PaintElement(Color.FromArgb(89, 139, 235)));
        UltraChart1.ColorModel.Skin.PEs.Add(new PaintElement(Color.FromArgb(255, 255, 85)));
        UltraChart1.ColorModel.Skin.PEs.Add(new PaintElement(Color.FromArgb(162, 18, 6)));
        UltraChart1.ColorModel.Skin.PEs.Add(new PaintElement(Color.FromArgb(146, 208, 80)));
        UltraChart1.ColorModel.Skin.PEs.Add(new PaintElement(Color.FromArgb(193, 128, 14)));
        UltraChart1.ColorModel.Skin.PEs.Add(new PaintElement(Color.FromArgb(255, 209, 0)));
        UltraChart1.ColorModel.Skin.PEs.Add(new PaintElement(Color.FromArgb(222, 0, 0)));
        UltraChart1.ColorModel.Skin.ApplyRowWise = true;

        if (cType == 0)
            UltraChart1.ChartType = Infragistics.UltraChart.Shared.Styles.ChartType.StackBarChart;
        else
            UltraChart1.ChartType = Infragistics.UltraChart.Shared.Styles.ChartType.Stack3DBarChart;

        UltraChart1.Legend.Visible = true;
        UltraChart1.Legend.Location = Infragistics.UltraChart.Shared.Styles.LegendLocation.Left;
        UltraChart1.DataSource = table;
        UltraChart1.DataBind();
        UltraChart1.ColorModel.Skin.ApplyRowWise = true;
