In This Topic

Combo chart is a combination of two or more chart types in a single plot area. For instance, a bar and line chart in a single plot. Combination charts are best used to compare the different data sets that are related to each other, such as actual and target values, total revenue and profit, temperature and precipitation etc. Note that these charts may require multiple axes to cater different scales.

Combo chart

 Combo chart can be used to interpret and understand different type of data that is completely unrelated (for instance: price and volume) or to plot one or more data series on the secondary axis.

Using Code

Refer to the following example code to add Combo Chart:

Java
Copy Code 
private static void ComboCharts() {
    // Initialize workbook
    Workbook workbook = new Workbook();
    // Fetch default worksheet
    IWorksheet worksheet = workbook.getWorksheets().get(0);

    // Prepare data for chart
    worksheet.getRange("A1:C17")
            .setValue(new Object[][] {
                { "Mobile Phones", "Laptops", "Tablets" }, 
                { 1350, 120, 75 },
                { 1500, 90, 35 }, 
                { 1200, 80, 50 }, 
                { 1300, 80, 80 }, 
                { 1750, 90, 100 }, 
                { 1640, 120, 130 },
                { 1700, 120, 95 }, 
                { 1100, 90, 80 }, 
                { 1350, 120, 75 }, 
                { 1500, 90, 35 }, 
                { 1200, 80, 50 }, });
    worksheet.getRange("A:C").getColumns().autoFit();

    // Add Combination Chart
    IShape comboChartShape = worksheet.getShapes().addChart(ChartType.Combo, 250, 20, 360, 230);
    // Adding series to SeriesCollection
    comboChartShape.getChart().getSeriesCollection().add(worksheet.getRange("A1:C17"), RowCol.Columns);

    // Configure Chart Title
    comboChartShape.getChart().getChartTitle().setText("Annual Sales Record-Combination Chart");
    ISeries series1 = comboChartShape.getChart().getSeriesCollection().get(0);
    ISeries series2 = comboChartShape.getChart().getSeriesCollection().get(1);
    ISeries series3 = comboChartShape.getChart().getSeriesCollection().get(2);

    // Change series type to make it Combination chart of different ChartTypes
    series1.setChartType(ChartType.Area);
    series2.setChartType(ChartType.ColumnStacked);
    series3.setChartType(ChartType.Line);

    // Set axis group
    series2.setAxisGroup(AxisGroup.Secondary);
    series3.setAxisGroup(AxisGroup.Secondary);

    // Configure axis scale and unit
    IAxis value_axis = comboChartShape.getChart().getAxes().item(AxisType.Value);
    IAxis value_second_axis = comboChartShape.getChart().getAxes().item(AxisType.Value, AxisGroup.Secondary);
    value_axis.setMaximumScale(1800);
    value_axis.setMajorUnit(450);
    value_second_axis.setMaximumScale(300);
    value_second_axis.setMajorUnit(75);

    // Saving workbook to Xlsx
    workbook.save("24-ComboChart.xlsx", SaveFileFormat.Xlsx);
