Need to Display Label with Pie chart. (C#)

[ArunP_S]

Hi All,

I am having a code which displays Pie chart and label of the polygon.

But when I display Pie char the label is not displayed. What am I missing / doing wrong.

Regards,

Arun

Here is the Code i am using

private void DisplayLabels(ILayer pFLayer, string feildName)
        {
          
            IGeoFeatureLayer pGeoFeatureLayer;
            pGeoFeatureLayer = (IGeoFeatureLayer)pFLayer;
            //string strFieldName = "Name";
            IAnnotateLayerPropertiesCollection pAnnoLayerPropsColl;
            pAnnoLayerPropsColl = pGeoFeatureLayer.AnnotationProperties;
            pGeoFeatureLayer.DisplayAnnotation = true;
            IAnnotateLayerProperties pAnnoLayerProps;
            IElementCollection iec;
            pAnnoLayerPropsColl.QueryItem(0, out pAnnoLayerProps, out iec, out iec);
            ILabelEngineLayerProperties pLabelEngineLayerProps;
            pLabelEngineLayerProps = (ILabelEngineLayerProperties)pAnnoLayerProps;
            pAnnoLayerPropsColl.Add(pAnnoLayerProps);
            pLabelEngineLayerProps.BasicOverposterLayerProperties.PointPlacementOnTop = true;
            pLabelEngineLayerProps.Expression = "[" + feildName + "]";
        }


private void displayPieChartmdbtable(IFeatureLayer FirstLayer, int maxval)
        {
            IChartRenderer pChartRenderer;
            IRendererFields pRendererFields;
            IPieChartRenderer pPieChartRenderer;
            IGeoFeatureLayer pGeoFeatureLayer;

         
               
                axMapControl1.ClearLayers();
                pGeoFeatureLayer = (IGeoFeatureLayer)FirstLayer;

                pChartRenderer = new ChartRenderer();
                pRendererFields = (IRendererFields)pChartRenderer;

                int numberOfClasses = AddFeildsToRendererAccordingToUserSelection(ref pRendererFields);

                pPieChartRenderer = (IPieChartRenderer)pChartRenderer;

               // calculateMaxValueofShapeFile(FirstLayer);

                IPieChartSymbol pPieChartSymbol = CreatePieChart(pChartRenderer, numberOfClasses, maxval);

                //' Disable overpoaster so that charts appear in the centre of polygons 
                pChartRenderer.UseOverposter = false;
                //' Update the renderer and refresh the screen  
              
                pPieChartRenderer.MinSize = 6;
                pPieChartRenderer.MinValue = 300;
                pPieChartRenderer.FlanneryCompensation = false;
                pChartRenderer.ChartSymbol = (IChartSymbol)pPieChartSymbol;
                pChartRenderer.CreateLegend();
                pGeoFeatureLayer.Renderer = (IFeatureRenderer)pChartRenderer;
                axMapControl1.AddLayer(pGeoFeatureLayer);
               // axMapControl1.Update();
                //axMapControl1.Extent = Current_Envelope;
          

        }
