Initialize chart

Create a chart object by calling the slide.Charts.Add method and specify the chart type to OfficeChartType.Funnel enum value.

            //Create the chart
            IPresentationChart chart = slide.Charts.AddChart(50, 50, 500, 400);
 
            //Set chart type to Funnel
            chart.ChartType = OfficeChartType.Funnel;

Assign data

Set a range of data from the chartData value to chart’s DataRange property. To plot the series values in column and categories in row, set chart’s IsSeriesInRows property to false.

            //Set region of Chart data
            chart.DataRange = chart.ChartData[1, 1, 8, 2];
 
            //Set chart series in column for assigned data region
            chart.IsSeriesInRows = false;

Apply basic chart elements

Add the basic elements like chart title, data labels and legend with the below list of properties.

ChartTitle of chart object.
Set DataLabels via DefaultDataPoint.
Set TRUE to chart’s HasLegend property, to show the legend.

              //Apply chart elements
              //Set Chart Title
              chart.ChartTitle = "Funnel Chart";
 
              //Set Legend
              chart.HasLegend = false;
              
              //Set Datalabels
              IOfficeChartSerie serie = chart.Series[0];
              serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
