This article explains how to create combination chart in Excel using Syncfusion Excel (XlsIO) library.

What is a combination chart?

Combination charts combine two or more chart types to make the data easy to understand. These charts can be used charts when the numbers in your data vary widely from data series to data series, or you have mixed type of data.

Cretae Combination Chart in Excel

Combination Chart

To create a combination chart in Excel using XlsIO, you need to do the following steps.

Steps to create combination chart:

Step 1: Initialize chart

Create a chart object by calling the worksheet.Charts.Add method.

C#

            //Create the chart
            IChartShape chart = worksheet.Charts.Add();

 

Step 2: Assign data

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

C#

          //Set region of Chart data
            chart.DataRange = worksheet["A1:C13"];
 
            //Set chart series in column for assigned data region
            chart.IsSeriesInRows = false;

 

Step 3: Select SerieType to create a combination chart

Set different SerieType value to the series. By doing this, chart type will be changed to combination chart type.

C#

            //Set Serie type
            IChartSerie serie1 = chart.Series[0];
            IChartSerie serie2 = chart.Series[1];       
            serie1.SerieType = ExcelChartType.Column_Clustered;
            serie2.SerieType = ExcelChartType.Line;
            serie2.UsePrimaryAxis = false;

 

Note:

For creating a combination chart, the chart must have minimum two series. Setting different SerieType property or UsePrimaryAxis property, the chart will be changed to combination chart type.

Step 4: Apply basic chart elements

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

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

C#

              //Apply chart elements
              //Set Chart Title
              chart.ChartTitle = "Combination Chart";
 
              //Set Datalabels
              serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
 
              //Set Legend
              chart.HasLegend = true;
              chart.Legend.Position = ExcelLegendPosition.Bottom;

 

Applicable ExcelChartType enum types to create combination chart using XlsIO

Below is the list of ExcelChartType enum values can be applied to the series to create a combination chart.

1. Area

  • Area
  • Area_Stacked
  • Area_Stacked_100

2. Bar

  • Bar_Clustered
  • Bar_Stacked
  • Bar_Stacked_100

3. Column

  • Column_Clustered
  • Column_Stacked
  • Column_Stacked_100

4. Line

  • Line
  • Line_Markers
  • Line_Stacked
  • Line_Stacked_100
  • Line_Markers_Stacked
  • Line_Markers_Stacked_100

5. Pie

  • Pie
  • PieOfPie
  • Pie_Bar
  • Doughnut

6. Radar

  • Radar
  • Radar_Markers
  • Radar_Filled

7. Scatter

  • Scatter_Markers
  • Scatter_Line
  • Scatter_Line_Markers
  • Scatter_SmoothedLine
  • Scatter_SmoothedLine_Markers
Note:

 

  1. Applying properties apart from the mentioned list might throw exception or the generate incorrect output document.
  2. Combination_Chart type cannot be set to series type.

                //Open existing workbook with data entered
                Assembly assembly = typeof(Program).GetTypeInfo().Assembly;
                Stream fileStream = assembly.GetManifestResourceStream("ChartSample.InputTemplate.xlsx");
                IWorkbook workbook = application.Workbooks.Open(fileStream);
                IWorksheet worksheet = workbook.Worksheets[0];
 
                //Initialize chart and assign data
                IChartShape chart = worksheet.Charts.Add();
                chart.DataRange = worksheet["A1:C13"];

                chart.HasLegend = true;
                chart.Legend.Position = ExcelLegendPosition.Bottom;
 
                //Set Serie type
                IChartSerie serie1 = chart.Series[0];
                IChartSerie serie2 = chart.Series[1];
                serie1.SerieType = ExcelChartType.Column_Clustered;
                serie2.SerieType = ExcelChartType.Line;
                serie2.UsePrimaryAxis = false;
 
                //set Data labels
                serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;                     
 
                //Positioning the chart in the worksheet
                chart.TopRow = 8;
                chart.LeftColumn = 1;
                chart.BottomRow = 23;
