What is a clustered column chart

Clustered column chart plots the data in the discrete vertical rectangles.

Clustered Column Chart Created using Presentation library

Steps to create the clustered column chart

Initialize chart

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

//Create the chart
IPresentationChart chart = slide.Charts.AddChart(100, 10, 700, 500);
 
//Set chart type to Column_Clustered
chart.ChartType = OfficeChartType.Column_Clustered;

Assign data and chart elements

Add the basic elements like chart title, data labels, and legend.

ChartTitle of chart object.
Set DataLabels via DefaultDataPoint.
Add CategoryLabels and Values
Set TRUE to chart’s HasLegend property to show the legend, else FALSE.

//Apply chart elements
//Set chart title
chart.ChartTitle = " Sales Report in Clustered Column Chart ";
 
//Set legend
chart.HasLegend = true;
              
//Set Datalabels, CategoryLabels, and Values
IOfficeChartSerie serie = chart.Series.Add();
serie.CategoryLabels = chart.ChartData[2,1,11,1];
serie.Values = chart.ChartData[2, 2, 6, 2];
serie.Bubbles = chart.ChartData[2, 3, 11, 3];
serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie.DataPoints.DefaultDataPoint.DataLabels.Position = OfficeDataLabelPosition.Bottom;

Applicable Properties of Clustered Column Chart

1. GapWidth (value should be between 0 and 500)

2. Overlap (value should be between -100 and 100)

3. IsVarycolor

NOTE: Applying other properties apart from the above list may throw exception or the changes will not be reflected in the output document because, those properties are not related to column/bar chart.
