    Configure Chart Series
    In This Topic

    DsExcel Java allows users to configure chart series in the following ways:

    DataPoint

    The Points collection in DsExcel Java is used to represent all the points in a specific series and the indexer notation of the IPoints interface to get a specific point in the series. Also, you can use the getDataLabel method of the IPoint interface in order to get data label of a specific point.

    Set the format of DataPoint

    In order to set data point format for the chart added in your worksheet, refer to the following example code.

    Java
    Copy Code 
    IShape shape = worksheet.getShapes().addChart(ChartType.ColumnClustered, 250, 20, 360, 230);
worksheet.getRange("A1:D6").setValue(
        new Object[][] { { null, "S1", "S2", "S3" }, { "Item1", 10, 25, 25 }, { "Item2", -51, -36, 27 },
                { "Item3", 52, -85, -30 }, { "Item4", 22, 65, 65 }, { "Item5", 23, 69, 69 } });
shape.getChart().getSeriesCollection().add(worksheet.getRange("A1:D6"), RowCol.Columns, true, true);
ISeries series1 = shape.getChart().getSeriesCollection().get(0);
        
series1.getPoints().get(2).getFormat().getFill().getColor().setRGB(Color.FromArgb(0, 176, 240));
series1.getPoints().get(2).getFormat().getLine().getColor().setRGB(Color.GetBlue());

    Configure secondary section for pie of a pie chart

    You can use the setSecondaryPlot method of the IPoint interface to set if the point lies in the secondary section of either a pie of pie chart or a bar of pie chart.

    In order to configure secondary section for pie of a pie chart, refer to the following example code.

    Java
    Copy Code 
    IShape shape = worksheet.getShapes().addChart(ChartType.PieOfPie, 250, 20, 360, 230);
worksheet.getRange("A1:D6").setValue(
        new Object[][] { { null, "S1", "S2", "S3" }, { "Item1", 10, 25, 25 }, { "Item2", -51, -36, 27 },
                { "Item3", 52, -85, -30 }, { "Item4", 22, 65, 65 }, { "Item5", 23, 69, 69 } });
shape.getChart().getSeriesCollection().add(worksheet.getRange("A1:D6"), RowCol.Columns, true, true);
        
ISeries series1 = shape.getChart().getSeriesCollection().get(0);
series1.setHasDataLabels(true);
        
shape.getChart().getChartGroups().get(0).setSplitType(ChartSplitType.SplitByCustomSplit);
series1.getPoints().get(0).setSecondaryPlot(true);
series1.getPoints().get(1).setSecondaryPlot(false);
series1.getPoints().get(2).setSecondaryPlot(true);
series1.getPoints().get(3).setSecondaryPlot(false);
series1.getPoints().get(4).setSecondaryPlot(true);

    DataLabel

    You can use the DataLabels collection to represent the collection of all the data labels for a specific series.

    The getFormat method of the IDataLabel interface can be used to set font style, fill, line and 3-D formatting for all the data labels of a specific series. Users can also configure the layout of the data labels using other methods of the IDataLabel interface.

     

    Set all data labels and specific data label format for series

    In order to set all data labels and specific data label format of a series, refer to the following example code.

    Java
    Copy Code 
    IShape shape = worksheet.getShapes().addChart(ChartType.ColumnClustered, 250, 20, 360, 230);
worksheet.getRange("A1:B5").setValue(
        new Object[][] { { null, "S1" }, { "Item1", -20 }, { "Item2", 30 }, { "Item3", 50 }, { "Item3", 40 } });
shape.getChart().getSeriesCollection().add(worksheet.getRange("A1:B5"), RowCol.Columns, true, true);
        
ISeries series1 = shape.getChart().getSeriesCollection().get(0);
series1.setHasDataLabels(true);
        
// set series1's all data label's format.
series1.getDataLabels().getFormat().getFill().getColor().setRGB(Color.GetPink());
series1.getDataLabels().getFormat().getLine().getColor().setRGB(Color.GetGreen());
series1.getDataLabels().getFormat().getLine().setWeight(1);

// set series1's specific data label's format.
series1.getDataLabels().get(2).getFormat().getFill().getColor().setRGB(Color.GetLightGreen());
series1.getPoints().get(2).getDataLabel().getFormat().getLine().getColor().setRGB(Color.GetGray());
series1.getPoints().get(2).getDataLabel().getFormat().getLine().setWeight(2);

    Customize data label text

    In order to set the text of the data label as per your choice, refer to the following example code.

    Java
    Copy Code 
    IShape shape = worksheet.getShapes().addChart(ChartType.ColumnClustered, 250, 20, 360, 230);
worksheet.getRange("A1:B5").setValue(new Object[][] { { null, "S1", "S2" }, { "Item1", -20 }, { "Item2", 30 },
        { "Item3", 50 }, { "Item3", 40 } });
shape.getChart().getSeriesCollection().add(worksheet.getRange("A1:B5"), RowCol.Columns, true, true);
ISeries series1 = shape.getChart().getSeriesCollection().get(0);
series1.setHasDataLabels(true);

// customize data label's text.
series1.getDataLabels().setShowCategoryName(true);
series1.getDataLabels().setShowSeriesName(true);
series1.getDataLabels().setShowLegendKey(true);

    Note: With version 7.0, the return value of getParent method of IDataLabel interface is changed from IPoint to Object, which will cause the compilation failure or runtime error in your existing projects. To avoid this, you must add explicit conversion of the object to IPoint as follows:

    C#
    Copy Code 
    // Following will cause a compilation error.
IPoint pt = series1.getDataLabels().get(0).getParent();
// Add explicit conversion to IPoint.
IPoint pt = (IPoint)series1.getDataLabels().get(0).getParent();

    Trendline

    The Trendlines collection in DsExcel Java is used to represent a collection of trend lines for a specific series. You can use the get method of the ITrendlines interface to create a new trendline for a specific series. Also, the indexer notation of the ITrendlines interface can be used to get a specific trend line.

    Add trendline for series and configure its style

    In order to add trendline for series and configure its style, refer to the following example code.

    Java
    Copy Code 
    IShape shape = worksheet.getShapes().addChart(ChartType.ColumnClustered, 200, 30, 300, 300);
Object[][] data = new Object[][] { { null, "S1", "S2", "S3" }, { "Item1", 10, 25, 25 },
        { "Item2", -51, -36, 27 }, { "Item3", 52, -85, -30 }, { "Item4", 22, 65, 65 },
        { "Item5", 23, 69, 69 } };
worksheet.getRange("A1:D6").setValue(data);
shape.getChart().getSeriesCollection().add(worksheet.getRange("A1:D6"), RowCol.Columns, true, true);

ISeries series1 = shape.getChart().getSeriesCollection().get(0);
series1.getTrendlines().add();
series1.getTrendlines().get(0).setType(TrendlineType.Linear);
series1.getTrendlines().get(0).setForward(5);
series1.getTrendlines().get(0).setBackward(0.5);
series1.getTrendlines().get(0).setIntercept(2.5);
series1.getTrendlines().get(0).setDisplayEquation(true);
series1.getTrendlines().get(0).setDisplayRSquared(true);

    Add two trendlines for one series

    In order to add two trendlines for one series, refer to the following example code.

    Java
    Copy Code 
    IShape shape = worksheet.getShapes().addChart(ChartType.ColumnClustered, 200, 30, 300, 300);
Object[][] data = new Object[][] { { null, "S1", "S2", "S3" }, { "Item1", 10, 25, 25 },
        { "Item2", -51, -36, 27 }, { "Item3", 52, -85, -30 }, { "Item4", 22, 65, 65 },
        { "Item5", 23, 69, 69 } };
worksheet.getRange("A1:D6").setValue(data);
shape.getChart().getSeriesCollection().add(worksheet.getRange("A1:D6"), RowCol.Columns, true, true);

ISeries series1 = shape.getChart().getSeriesCollection().get(0);
series1.getTrendlines().add();
series1.getTrendlines().get(0).setType(TrendlineType.Linear);
series1.getTrendlines().get(0).setForward(5);
series1.getTrendlines().get(0).setBackward(0.5);
series1.getTrendlines().get(0).setIntercept(2.5);
series1.getTrendlines().get(0).setDisplayEquation(true);
series1.getTrendlines().get(0).setDisplayRSquared(true);

series1.getTrendlines().add();
series1.getTrendlines().get(1).setType(TrendlineType.Polynomial);
series1.getTrendlines().get(1).setOrder(3);

    Set trendline's name

    You can also set the trendline's name in DsExcel using the setName method of ITrendline interface. The trendline's name can also be exported to a PDF document.

    Refer to the following example code to set trendline's name in DsExcel.

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

// Add a chart
IShape columnChart = worksheet.getShapes().addChart(ChartType.ColumnClustered, 300, 10, 300, 300);       
        
worksheet.getRange("A1:D6").setValue(new Object[][] 
{
{null, "S1", "S2", "S3"},
{"Item1", 10, 25, 25},
{"Item2", -51, -36, 27},
{"Item3", 52, -85, -30},
{"Item4", 22, 65, 65},
{"Item5", 23, 69, 69}
});

// Add series
columnChart.getChart().getSeriesCollection().add(worksheet.getRange("A1:D6"), RowCol.Columns, true, true);

// Get first series
ISeries series1 = columnChart.getChart().getSeriesCollection().get(0);

// Add a trend line
ITrendline trendline = series1.getTrendlines().add();

// Set trend line's name.
trendline.setName("Theoretical data");

//save to an excel file
workbook.save("TrendLineName.xlsx");

    Set trendline¡¯s label format

    You can also format the trendline equation label and export it to a PDF document, HTML file, or image using getDataLabel method in ITrendline interface, which gets the data label associated with the trendline. getDataLabel returns value only when setDisplayEquation or setDisplayRSquared of ITrendline interface is true. If both of them are false, the getDataLabel method will return null.

    You can use getFont, getFormat, getNumberFormat, getOrientation, getDirection, and getAutoText methods of IDataLabel interface to format the trendline equation label. DsExcel also provides delete method to delete the trendline equation label.

    Refer to the following example code to format the data label of the trendline:

    Java
    Copy Code 
    // Initialize Workbook.
IWorkbook workbook = new Workbook();

// Create a worksheet.
IWorksheet worksheet = workbook.getWorksheets().get(0);

// Add XYScatter chart.
IShape shape = worksheet.getShapes().addChart(ChartType.XYScatter, 250, 20, 360, 230);
worksheet.getRange("A1:C11").setValue(new Object[][] {
    { null, "Mktng Exp", "Revenue" },
    { "Company 1", 1849, 2911 },
    { "Company 2", 2708, 5777 },
    { "Company 3", 3474, 8625 },
    { "Company 4", 4681, 9171 },
    { "Company 5", 5205, 10308 },
    { "Company 6", 5982, 11779 },
    { "Company 7", 8371, 12138 },
    { "Company 8", 8457, 17074 },
    { "Company 9", 9554, 15729 },
    { "Company 10", 9604, 19610 }
    });
shape.getChart().getSeriesCollection().add(worksheet.getRange("B1:C11"), RowCol.Columns, true, true);
ISeries series1 = shape.getChart().getSeriesCollection().get(0);

// Add Trendline.
ITrendline trendline = series1.getTrendlines().add();
trendline.setType(TrendlineType.Linear);

// Display equation for the trendline.
trendline.setDisplayEquation(true);

// Format datalabel for trendline.
IDataLabel trendlineDataLabel = trendline.getDataLabel();
trendlineDataLabel.getFont().getColor().setRGB(Color.GetPurple());
trendlineDataLabel.getFont().setSize(11);
trendlineDataLabel.getFormat().getFill().getColor().setObjectThemeColor(ThemeColor.Accent4);
trendlineDataLabel.getFormat().getLine().getColor().setObjectThemeColor(ThemeColor.Accent2);

// Set paper size for PDF export.
worksheet.getPageSetup().setPaperSize(PaperSize.A3);

// Save the workbook.
workbook.save("DataLabelTrendline.xlsx");

// Export the workbook as a PDF document.
workbook.save("DataLabelTrendline.pdf");

    getParent method (ITrendline.getDataLabel().getParent()) will return the parent object of the specified trendline. Its return value type is an object with ITrendline as the return value.

    Java
    Copy Code 
    ITrendline trendline = (ITrendline)trendline.getDataLabel().getParent();

    Note: The trendline equation label does not support the following methods of IDataLabel interface; hence, calling them will throw a NotSupportedException:

    • getPosition
    • getSeparator
    • getShowBubbleSize
    • getShowCategoryName
    • getShowLegendKey
    • getShowPercentage
    • getShowSeriesName
    • getShowValue
    • getNumberFormatLinked
    • getTextFrame

    Limitations

    SpreadJS only supports the default equation and R-value; therefore, DsExcel cannot export the trendline data format to JSON and SJS.

        { "Item2", -51, -36, 27 }, { "Item3", 52, -85, -30 }, { "Item4", 22, 65, 65 },
        { "Item5", 23, 69, 69 } };
worksheet.getRange("A1:D6").setValue(data);
shape.getChart().getSeriesCollection().add(worksheet.getRange("A1:D6"), RowCol.Columns, true, true);

shape.getChart().getSeriesCollection().get(2).delete();
shape.getChart().getSeriesCollection().get(1).delete();
        
// Chart's series count is 1.
// int count = shape.getChart().getSeriesCollection().getCount();
shape.getChart().getSeriesCollection().getCount();
        
// set vary colors for column chart which only has one series.
shape.getChart().getColumnGroups().get(0).setVaryByCategories(true);

    Smooth Line

    You can use setSmooth method of ISeries Interface to smoothen the curves of line and scatter charts.

    Configure Smooth Property for Line Chart

    Refer to the following example code to configure setSmooth method for the line chart:

    Java
    Copy Code 
    // Create a workbook.
Workbook workbook = new Workbook();
        
// Get the active sheet.
IWorksheet worksheet = workbook.getActiveSheet();
        
// Set data for the chart.
Object[][] data = new Object[][]
{
    { null , "2017", "2018", "2019", "2020", "2021", "2022", "2023" },
    { "Mobile Phones",0.9,0.13,0.15,0.18,0.17,0.18,0.04 },
    { "Tablets", 0.05, 0.08, 0.12, 0.13, 0.15, 0.17, 0.54 },
    { "Household items",0.43,0.35,0.23,0.13,0.13,0.15,0.16 },
    { "Vehicles",0.51,0.55,0.45,0.55,0.08,0.45,0.46 },
    { "Groceries",0.51,0.55,0.25,0.77,0.05,0.45,0.56 },
    { "Personal care",0.35,0.2,1,0.23,0.33,0.5,1 },
};
        
// Add data to the range.
worksheet.getRange("A1:H7").setValue(data);

// Set style of the range.
worksheet.getRange("A1:H7").getStyle().setHorizontalAlignment(HorizontalAlignment.Center);
worksheet.getRange("A1:A7").setColumnWidth(18);

// Create line chart.
IShape shape = worksheet.getShapes().addChart(ChartType.Line, 10, 150, 400, 200);
shape.getChart().getSeriesCollection().add(worksheet.getRange("A1:H7"), RowCol.Columns, true, true);
shape.getChart().getChartTitle().setText("Product Sales");

// Set line curve setting.
for (ISeries item : shape.getChart().getSeriesCollection())
{
    // Set Smooth property to true.
    item.setSmooth(true);
}
    
// Save the workbook in xlsx and pdf formats.
workbook.save("SmoothLineChart.xlsx");
workbook.save("SmoothLineChart.pdf");
