Chart (13)
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

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.

public static void main(String[] args) {
//Create an instance of Workbook class
Workbook workbook = new Workbook();
//Get the first worksheet
Worksheet sheet = workbook.getWorksheets().get(0);
//Insert data to specified cells
sheet.getCellRange("A1").setValue("Country");

Create a Stacked Bar Chart in Excel
In stacked bar chart, data values of different series are stacked one over the other in a single bar. Compared with the clustered bar chart, the stacked bar chart provides a clearer view of part-to-whole comparison in each category. The following are the detailed steps to create a stacked 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 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.

This article demonstrates how to create chart with non-contiguous data in Excel using Spire.XLS for Java.
The example Excel file:
import com.spire.xls.*;
import com.spire.xls.charts.ChartSerie;
import java.awt.*;
public class ChartWithNonContiguousData {
public static void main(String[] args){
//Create a Workbook instance
Workbook workbook = new Workbook();
//Load the Excel file
workbook.loadFromFile("NonContiguousData.xlsx");
//Get the first worksheet
Worksheet sheet = workbook.getWorksheets().get(0);
//Add a clustered column chart to the worksheet
Chart chart = sheet.getCharts().add(ExcelChartType.ColumnClustered);
chart.setSeriesDataFromRange(false);
//Set chart position
chart.setLeftColumn(1);
chart.setTopRow(10);
chart.setRightColumn(10);
chart.setBottomRow(24);
//Add a series to the chart
ChartSerie cs1 = (ChartSerie)chart.getSeries().add();
//Set series name
cs1.setName(sheet.getCellRange("B1").getValue());
//Set category labels for the series using non-contiguous data
cs1.setCategoryLabels(sheet.getCellRange("A2:A3").addCombinedRange(sheet.getCellRange("A5:A6"))
.addCombinedRange(sheet.getCellRange("A8:A9")));
//Set values for the series using non-contiguous data
cs1.setValues(sheet.getCellRange("B2:B3").addCombinedRange(sheet.getCellRange("B5:B6"))
.addCombinedRange(sheet.getCellRange("B8:B9")));
//Specify the series type
cs1.setSerieType(ExcelChartType.ColumnClustered);
//Add a series to the chart
ChartSerie cs2 = (ChartSerie)chart.getSeries().add();
//Set series name
cs2.setName(sheet.getCellRange("C1").getValue());
//Set category labels for the series using non-contiguous data
cs2.setCategoryLabels(sheet.getCellRange("A2:A3").addCombinedRange(sheet.getCellRange("A5:A6"))
.addCombinedRange(sheet.getCellRange("A8:A9")));
//Set values for the series using non-contiguous data
cs2.setValues(sheet.getCellRange("C2:C3").addCombinedRange(sheet.getCellRange("C5:C6"))
.addCombinedRange(sheet.getCellRange("C8:C9")));
//Specify the series type
cs2.setSerieType(ExcelChartType.ColumnClustered);
//Set chart title
chart.setChartTitle("Chart");
chart.getChartTitleArea().getFont().setSize(20);
chart.getChartTitleArea().setColor(Color.black);
chart.getPrimaryValueAxis().hasMajorGridLines(false);
//Save the result file
