        chartText.Row = chartText.Column = -2;
        chartText.Visible = true;
        chartText.ItemFormatString = "<DATA_VALUE:0.##>";       
        chartText.VerticalAlign = StringAlignment.Far;
        ((ColumnChartAppearance)layer2.ChartTypeAppearance).ChartText.Add(chartText);
        ((ColumnChartAppearance)layer2.ChartTypeAppearance).NullHandling = NullHandling.Zero;

    i'm not sure why your chart is not displaying, and can't guess at the problem based on the source code you provided.  here are some things to check:

    have you added a ChartLayerAppearance object to the layers collection with ChartType = ColumnChart?

    does the column layer have its ChartArea, AxisX, and AxisY properties set?

    does AxisX have SetLabelAxisType = GroupBySeries and DataType = String?

    does AxisY have DataType = Numeric?

    are there one or more NumericSeries in the layer's Series collection?
