Funnel

Funnel charts help in visualizing sequential stages in a linear process such as order fulfillment. In such processes, each stage represents a proportion (percentage) of the total. Therefore, the chart takes the funnel shape with the first stage being the largest and each subsequent stage smaller than the predecessor. The Funnel charts can be used to represent stages in a sales process and represent the amount of potential revenue for each stage. This type of chart is useful in finding potential problem areas in an organization's sales processes. For instance, with Funnel charts, a user can plot the order fulfillment process that tracks number of orders getting across a stage.

Using Code

Refer to the following code to add a Funnel chart:

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

    // Prepare data for chart
    worksheet.getRange("A1:B9")
            .setValue(new Object[][] { 
            { null, "Sales" }, 
            { "Consultation", 140000 }, 
            { "Prospects", 120000 },
            { "Qualified", 100000 }, 
            { "Negotiations", 80000 }, 
            { "Prototype", 60000 },
            { "Closing", 40000 }, 
            { "Won", 20000 }, 
            { "Finalized", 10000 } });
    worksheet.getRange("A:B").getColumns().autoFit();

    // Add Funnel Chart
    IShape funnelChartshape = worksheet.getShapes().addChart(ChartType.Funnel, 300, 20, 300, 200);
    funnelChartshape.getChart().getSeriesCollection().add(worksheet.getRange("A1:B9"));

    // Configure Chart Title
    funnelChartshape.getChart().getChartTitle().setText("Sales Pipeline");

    // Configure Axis
    IAxis axis = funnelChartshape.getChart().getAxes().item(AxisType.Category, AxisGroup.Primary);
    axis.setVisible(true);

    // Saving workbook to Xlsx
    workbook.save("34-FunnelChart.xlsx", SaveFileFormat.Xlsx);
