Java: Create a Waterfall Chart in Excel

A waterfall chart, also called a bridge chart or a cascade chart, is one of the most visually descriptive charts in Excel. It shows the cumulative effect of positive and negative contributions over a period of time, which is useful in many scenarios where quantitative analysis is required, such as visualizing profit and loss statements, showing budget changes in a project, or monitoring shop inventories. In this article, you will learn how to create a waterfall chart in Excel in Java using Spire.XLS for Java.

Install Spire.XLS for Java

First of all, you're required to add the Spire.Xls.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Create a Waterfall Chart in Excel in Java

Waterfall charts are ideal for analyzing financial statements. To create a waterfall chart, you could first add a chart to a specified worksheet using Worksheet.getCharts().add() method, and then set the chart type to Waterfall using Chart.setChartType(ExcelChartType.WaterFall) method. The following are the detailed steps.

  • Create a Workbook instance.
  • Load a sample Excel document using Workbook.loadFromFile() method.
  • Get a specified worksheet by its index using Workbook.getWorksheets().get() method.
  • Add a chart to the worksheet Worksheet.getCharts().add() method, and then set the chart type to waterfall using Chart.setChartType(ExcelChartType.WaterFall) method.
  • Set data range for the chart using Chart.setDataRange() method.
  • Set position and title of the chart.
  • Get a specified data series of the chart, and then set specific data points in the chart as totals or subtotals using ChartSerie.getDataPoints().get().setAsTotal() method.
  • Show the connector lines between data points using ChartSerie.getFormat().showConnectorLines(true) method.
  • Show data labels for data points, and set the legend position of the chart.
  • Save the result document using Workbook.saveToFile() method.
  • Java
import com.spire.xls.*;

public class WaterfallChart {
    public static void main(String []args){
        //Create a Workbook object
        Workbook workbook=new Workbook();

        //Load a sample Excel document
        workbook.loadFromFile("data.xlsx");

        //Get the first worksheet
        Worksheet sheet=workbook.getWorksheets().get(0);

        //Add a waterfall chart to the worksheet
        Chart chart=sheet.getCharts().add();
        chart.setChartType(ExcelChartType.WaterFall);

        //Set data range for the chart
        chart.setDataRange(sheet.getRange().get("A2:B11"));

        //Set position of the chart
        chart.setLeftColumn(4);
        chart.setTopRow(2);
        chart.setRightColumn(15);
        chart.setBottomRow(23);

        //Set chart title
        chart.setChartTitle("Income Statement");

        //Set specific data points in the chart as totals or subtotals
        chart.getSeries().get(0).getDataPoints().get(2).setAsTotal(true);
        chart.getSeries().get(0).getDataPoints().get(7).setAsTotal(true);
        chart.getSeries().get(0).getDataPoints().get(9).setAsTotal(true);

        //Show the connector lines between data points
        chart.getSeries().get(0).getFormat().showConnectorLines(true);

        //Show data labels for data points
        chart.getSeries().get(0).getDataPoints().getDefaultDataPoint().getDataLabels().hasValue(true);
        chart.getSeries().get(0).getDataPoints().getDefaultDataPoint().getDataLabels().setSize(8);

        //Set the legend position of the chart
        chart.getLegend().setPosition(LegendPositionType.Top);

        //Save the result document
        workbook.saveToFile("WaterfallChart.xlsx",FileFormat.Version2016);
    }
}

Java: Create a Bar Chart in Excel

A bar chart is a type of graph that represents or summarizes data in the form of horizontal rectangular bars of equal width but different lengths. In MS Excel, the bar chart is a great tool to compare data among different groups, which helps users to analyze data and draw conclusions quickly. In this article, you will learn how to programmatically create a clustered bar chart or a stacked bar chart in an Excel worksheet using Spire.XLS for Java.

Install Spire.XLS for Java

First of all, you're required to add the Spire.Xls.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Create a Clustered Bar Chart in Excel

In clustered bar chart, data values of different series are displayed in separate bars side-by-side, which allows a direct comparison of multiple data series per category. The following are the detailed steps to create a clustered bar chart in an Excel worksheet.

  • Create an instance of Workbook class.
  • Get a specified worksheet by its index using Workbook.getWorksheets().get() method.
  • Add some data to specified cells and set the cell styles.
  • Add a 2D clustered bar chart to the specified worksheet using Worksheet.getCharts().add(ExcelChartType.BarClustered) method.
  • Set data range for the chart using Chart.setDataRange(CellRange dataRange) method.
  • Set the position and title of the chart.
  • Get the primary category axis of the chart using Chart.getPrimaryCategoryAxis() method, and then set the display text and title of the category axis using the methods under ChartCategoryAxis class.
  • Get the primary value axis of the chart using Chart.getPrimaryValueAxis() method, and then set the title, minimum value and major gridlines of the value axis using the methods under ChartValueAxis class.
  • Loop through the data series of the chart, and then show data labels for the data points of each data series by setting the value of ChartSerie.getDataPoints().getDefaultDataPoint().getDataLabels().hasValue() method to true.
  • Set the position of chart legend using Chart.getLegend().setPosition() method.
  • Save the result file using Workbook.saveToFile() method.

  • Get a specified worksheet by its index using Workbook.getWorksheets().get() method.
  • Add some data to specified cells and set the cell styles.
  • Add a 2D stacked bar chart to the specified worksheet using Worksheet.getCharts().add(ExcelChartType.BarStacked) method.
  • Set data range for the chart using Chart.setDataRange(CellRange dataRange) method.
  • Set position, title, category axis title and value axis title for the chart.
  • Loop through the data series of the chart, and then show data labels for the data points of each data series by setting the value of ChartSerie.getDataPoints().getDefaultDataPoint().getDataLabels().hasValue() method to true.
  • Set the position of chart legend using Chart.getLegend().setPosition() method.
  • Save the result file using Workbook.saveToFile() method.

Java: Add a Text Box to a Chart in Excel

Text box allows people to enter text in it and move it arbitrarily. When dealing with the chart in Excel document, if the text description of the original chart is not specific enough, you can add additional information to the chart by adding text boxes to it. This article will introduce how to add a text box to a chart programmatically using Spire.XLS for Java.

Install Spire.XLS for Java

First of all, you're required to add the Spire.Xls.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

<repositories>
    <repository>
        <id>com.e-iceblue</id>
        <name>e-iceblue</name>
        <url>https://repo.e-iceblue.com/nexus/content/groups/public/</url>
    </repository>
</repositories>
<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.xls</artifactId>
        <version>14.4.1</version>
    </dependency>
</dependencies>

Add a Text Box to a Chart

The detailed steps are listed as below.

  • Create a Workbook instance and load a sample Excel document using Workbook.loadFromFile() method.
  • Get a specified worksheet using Workbook.getWorksheets().get() method.
  • Get a specific chart using Worksheet.getCharts().get() method.
  • Add a text box to the chart using Chart.getShapes().addTextBox() method, and then add text content in the text box using ITextBoxLinkShape.setText() method.
  • Set the size and position of the added text box using the method offered by ITextBoxLinkShape interface.
  • Save the document to file using Workbook.saveToFile() method.
  • Java
import com.spire.xls.*;
import com.spire.xls.core.*;

public class addTextBoxToChart {
    public static void main(String[] args)throws Exception {
        //Create a Workbook instance
        Workbook workbook = new Workbook();

        //Load an Excel document
        workbook.loadFromFile("DoughnutChart.xlsx");

        //Get the first worksheet
        Worksheet sheet = workbook.getWorksheets().get(0);

        //Get the first chart
        Chart chart = sheet.getCharts().get(0);

        //Add a text box to the chart
        ITextBoxLinkShape textbox = chart.getShapes().addTextBox();
        textbox.setText("Modified by Louis on September 06, 2021");

        //Set the size and position of the text box
        textbox.setWidth(1100);
        textbox.setHeight(480);
        textbox.setLeft(2800);
        textbox.setTop(480);

        //Save the result file
        workbook.saveToFile("addTextBoxToChart.xlsx", ExcelVersion.Version2013);
    }
}
