    Configure Chart Series
    In This Topic

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

    DataPoint

    The Points collection in GcExcel 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);

    Trendline

    The Trendlines collection in GcExcel 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);

// 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");
