Creating Charts

Earlier people had to rely on scriptlets to gather the chart data and render the chart using an image element in the report template. JasperReports makes it simple now, as it has a built-in support for charts using the new chart component.

Using a new chart component, user needs to apply only the visual settings and define expressions that will help build the chart dataset. JasperReports uses JFreeChart as the underlying charting library. When configuring a new chart component, following three components are involved −

• The overall chart component.
• The chart dataset (which groups chart data-related settings).
• The chart plot (which groups visual settings related to the way the chart items are rendered).

JasperReports currently supports the following types of charts: Pie, Pie 3D, Bar, Bar 3D, XY Bar, Stacked Bar, Stacked Bar 3D, Line, XY Line, Area, XY Area, Stacked Area, Scatter, Bubble, Time Series, High-Low-Open-Close, Candlestick, Multiple Axis, Meter, Thermometer, and Gantt.

Chart Properties

Charts are normal report elements, so they share some of their properties with all the other report elements. There is a JRXML element called <chart>, used to create all type of charts. This element groups special chart-specific settings that apply to all types of charts.

Chart Sub-Elements

The sub-elements of <chart> element are −

• <reportElement> − These are displayable objects like static texts, text fields, images, lines, and rectangles that you put in your report template sections.
• <Box> − This element is used to surround charts by a border that's customizable on each side.
• <chartTitle> − This element is used to place the title of the chart. The position attribute decides the title position of the chart in the report. This element has attributes - Position (Values could be Top, Bottom, Left, Right. Deafult value is Top), color. <chartTitle> has fontand titleExpression as subelements.
• <chartSubtitle> − This element is used to place the subtitle of the chart. This element has attribute - color. <chartSubtitle> has fontand subtitleExpression as subelements.
• <chartLegend> − The element can control the font-related properties as well as the text color and the background color of the chart legend using this element. This element has attributes - textColor and backgroundColor.
• <anchorNameExpression> − This element creates the target for the anchor.
• <hyperlinkReferenceExpression> − This element contains a report expression indicating the name of the external resource (usually a URL).
• <hyperlinkAnchorExpression> − Hyperlink points to an anchor in an external resource.
• <hyperlinkPageExpression> − Hyperlink points to a page in the current report.
• <hyperlinkTooltipExpression> − This element controls the ToolTip of hyperlink. The type of the expression should be java.lang.String.
• <hyperlinkParameter> − This element when present generates a final hyperlink depending on the parameter values.

Chart attributes

Attributes in the <chart> element available for all chart types are −

• isShowLegend − This attribute is used to determine, if a chart legend will be displayed on the report. Values could be true, or false. Default value is true.
• evaluationTime − Determines when the chart's expression will be evaluated. Values could be Now, Report, Page, Column, Group, Band. Default value is Now.
• evaluationGroup − This attribute determines the name of the group to be used to evaluate the chart's expressions. The value for this attribute must match the name of the group, we would like to use as the chart's evaluation group.
• hyperlinkType − This attribute can hold any text value. Default value is None. This means, neither the text fields nor the images represent hyperlinks, even if the special hyperlink expressions are present.
• hyperlinkTarget − This attribute helps to customize the behavior of the specified link when it is clicked in the viewer. Values could be Self, or Blank. Default value is Self.
• bookmarkLevel − This attribute when set to a positive integer, generates bookmarks in the reports exported to PDF. Default value is 0.
• customizerClass − This is the name of a class (optional) that can be used to customize the chart. The value for this element must be a String containing the name of a customizer class.

Chart customization

As mentioned above, JasperReports uses JFreeChart as the underlying charting library. JFreeChart contains features that are directly not supported by JasperReports. We can take advantage of these features by supplying a customizer class via the customizerClass attribute in <chart> element. A customizer class is nothing, but an implementation of the net.sf.jasperreports.engine.JRChartCustomizer interface. The easiest way to implement this interface is by extending the net.sf.jasperreports.engine.JRAbstractChartCustomizer class and thus having access to parameters, fields, and variables for more flexible chart customization based on report data.

Chart Datasets

One of the common properties across all chart types is <dataset> element. Chart datasets help mapping report data and retrieving chart data at runtime. Each chart type contains different sub-elements to define chart's expressions. These expressions define the data used to generate the chart. All of these sub-elements contain a <dataset> element that defines when the chart's expressions are evaluated and reset.

Several types of chart datasets are available in JasperReports because each type of chart works with certain datasets: Pie, Category, XY, Time Series, Time Period, XYZ, and High-Low. Each of these dataset types implements net.sf.jasperreports.engine.JRChartDataset interface that define chart datasets. All chart datasets initialize and increment in the same way; however, they differ only in the type of data or data series they map.

Dataset Properties

Table given below summarizes the attributes of the element <dataset> −

Attribute	Description	Values
resetType	This attribute determines when the value of the chart expression is to be reset.	None, Report, Page, Column, Group. Default value is Report.
resetGroup	This attribute determines the name of the group at which the chart expression value is reset.	The value for this attribute must match the name of any group declared in the JRXML report template.
incrementType	This attribute determines when to recalculate the value of the chart expression.	None, Report, Page, Column, Group. Default value is "None".
incrementGroup	This attribute determines the name of the group at which the chart expression is recalculated.	The value for this attribute must match the name of a group declared in the JRXML report template.

The following table summarizes the sub-elements of the element <dataset> −

Sub element	Description
<incrementWhenExpression>	The way a chart dataset is incremented can be customized by filtering out unwanted data through the use of this sub element.
<datasetRun>	This contains information required to instantiate a report subdataset.

Dataset Types

Specific dataset types are explained below −

Pie Dataset

A pie dataset is characterized by the following expressions −

• <keyExpression> − represents the categories that will make up the slices in the pie chart. This expression can return any java.lang.Comparable object.
• <valueExpression> − produces the values that correspond to each category/key in the dataset. Values are always java.lang.Number objects.
• <labelExpression> − if this expression is missing, the chart will display default labels for each slice in the pie chart. Use this expression, which returns java.lang.String values, to customize the item labels for the pie chart.
• <sectionHyperlink> − sets hyperlinks associated with the pie sections.

Category Dataset

A category dataset is characterized by the <categorySeries> element, which contains −

• <seriesExpression> − indicates the name of the series. This expression can return any java.lang.Comparable object.
• <categoryExpression> − returns the name of the category for each value inside the series specified by the series expression. Categories are java.lang.Comparable objects.
• <valueExpression> − produces the values that correspond to each category in the dataset. Values are always java.lang.Number objects.
• <labelExpression> − if this expression is missing, the chart will display default labels for each item in the chart. Use this expression, which returns java.lang.String values, to customize the item labels for the chart.
• <itemHyperlink> − sets hyperlinks associated with chart items.

XY Dataset

An XY dataset is characterized by the <xySeries> element, which contains −

XYZ Dataset

An XYZ dataset is characterized by the <xyzSeries> element, which contains −

• <seriesExpression> − indicates the name of the series. This expression can return any java.lang.Comparable object.
• <xValueExpression> − returns the java.lang.Number value representing the X value from the (x, y, z) item that will be added to the current data series.
• <yValueExpression> − returns the java.lang.Number value representing the Y value from the (x, y, z) item that will be added to the current data series.
• <zValueExpression> − returns the java.lang.Number value representing the Z value from the (x, y, z) item that will be added to the current data series.
• <labelExpression> − if this expression is missing, the chart will display default labels for each item in the chart. Use this expression, which returns java.lang.String values, to customize the item labels for the chart.
• <itemHyperlink> − sets hyperlinks associated with the chart items.

Time Series Dataset

A time series dataset is characterized by the timePeriod attribute, and the <timeSeries> element. The timePeriod attribute specifies the type of the data series inside the dataset. Time series can contain numeric values associated with days, months, years, or other predefined time periods. Possible values are: Year, Quarter, Month, Week, Day - this is the default value, Hour, Minute, Second, Millisecond.

The <timeSeries> element contains −

• <seriesExpression> − indicates the name of the series. This expression can return any java.lang.Comparable object.
• <timePeriodExpression> − returns a java.util.Date value from which the engine will extract the corresponding time period depending on the value set for the timePeriod attribute mentioned above.
• <valueExpression> − returns the java.lang.Number value to associate with the corresponding time period value when incrementing the current series of the dataset.
• <labelExpression> − if this expression is missing, the chart will display default labels for each item in the chart. Use this expression, which returns java.lang.String values, to customize the item labels for the chart.
• <itemHyperlink> − sets hyperlinks associated with the chart items.

Time Period Dataset

A time period dataset is characterized by the <timePeriodSeries> element, which contains −

• <seriesExpression> − indicates the name of the series. This expression can return any java.lang.Comparable object.
• <startDateExpression> − specifies the beginning of the date interval with which the numeric value will be associated when it is added to the time period series.
• <endDateExpression> − specifies the end of the date interval with which the numeric value will be associated when it is added to the time period series.
• <valueExpression> − returns the java.lang.Number value to associate with the current date interval specified by the start date and end date expressions.
• <labelExpression> − if this expression is missing, the chart will display default labels for each item in the chart. Use this expression, which returns java.lang.String values, to customize the item labels for the chart.
• <itemHyperlink> − sets hyperlinks associated with the chart items.

High Low Dataset

A high low dataset is characterized by the following expressions −

• <seriesExpression> − currently, only one series is supported inside a High-Low or Candlestick chart. However, this single series must be identified by a java.lang.Comparable value returned by this expression, and it must also be used as the series name in the chart's legend.
• <dateExpression> − returns the date to which the current (high, low, open, close, volume) item refers.
• <highExpression> − returns a java.lang.Number value, which will be part of the data item added to the series when the dataset gets incremented.
• <lowExpression> − returns a java.lang.Number value, which will be part of the data item added to the series when the dataset gets incremented.
• <openExpression> − returns a java.lang.Number value, which will be part of the data item added to the series when the dataset gets incremented.
• <closeExpression> − returns a java.lang.Number value, which will be part of the data item added to the series when the dataset gets incremented.
• <volumeExpression> − a numeric expression that returns the volume value to use for the current data item. It is used only for Candlestick charts.
• <itemHyperlink> − sets hyperlinks associated with the chart items.

Value Dataset

This is a special chart dataset implementation that contains a single value and is used for rendering Meter and Thermometer charts. The value is collected using the <valueExpression> expression.

Chart Plots

Another common JRXML element through all chart types is the <plot> element. This allows us to define several of chart's characteristics like orientation and background color. Plots differ, based on the type of chart.

Plot Attribute

The table given below summarizes the attributes of <plot> element −

Attribute	Description	Values
backcolor	This attribute defines the chart's background color.	Any six digit hexadecimal value is a valid value for this attribute. The hexadecimal value must be preceded by a #.
orientation	This attribute defines the chart's orientation.	Horizontal,Vertical Default value is "Vertical"
backgroundAlpha	This attribute defines the transparency of the chart's background color.	The valid values for this attribute include any decimal number between 0 and 1, inclusive. The higher the number, the less transparent the background will be. Default value is "1."
foregroundAlpha	This attribute defines the transparency of the chart's foreground colors.	The valid values for this attribute include any decimal number between 0 and 1, inclusive. The higher the number, the less transparent the background will be. Default value is "1."
labelRotation	This attribute allows rotation of text labels on x-axis to rotate clockwise or anti-clockwise. This attribute applies only to charts for which the x axis is not numeric or does not display dates.	Default value is "0.0."

The <plot> element has a subelement <seriesColor> which attributes are: seriesOrder and color. This element customizes colors for series, and their position within in the color sequence.

Example

To demonstrate the charts, let's write a new report template (jasper_report_template.jrxml). Here, we will add the <barChart> element to the <pageHeader> section and <pieChart> to <summary> section. We would be displaying in charts the marks obtained for each subject. Save it to the directory C:\tools\jasperreports-5.0.1\test. The contents of the file are as given below −

</jasperReport>

The details of the above file are as given below −

• The JRXML element used to create a bar chart is </barChart> in the <pageHeader>. It contains a </chart> sub-element, which contains a <reportElement> sub-element defining the chart's dimensions and position.
• The <dataset> element in a bar chart must be enclosed between <categoryDataset> and </categoryDataset> JRXML elements.
• <categoryDataset> must contain a <categorySeries> element. This element defines what data element the bars will represent (subject names, in this example).
• <categoryDataset> must also contain an element, which defines how the data will be separated into categories for comparison. Here, data is separated by subject names.
• The <valueExpression> element defines that what expression is used to determine the value of each bar in the chart. Here, we are using "marks".
• For the pie chart, we have used the element <pieChart> under the <summary> section. It contains a </chart> sub-element.
• The sub-element contains a report expression indicating what to use as a key in the chart. Here, we have used subjectName.
• The sub-element contains an expression used to calculate the value for the key. Here, we have used marks.

The java codes for report filling remains unchanged. The contents of the file C:\tools\jasperreports-5.0.1\test\src\com\tutorialspoint\JasperReportFill.java are as given below −

package com.tutorialspoint;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.data.JRBeanCollectionDataSource;

public class JasperReportFill {
   @SuppressWarnings("unchecked")
   public static void main(String[] args) {
      String sourceFileName = 
         "C://tools/jasperreports-5.0.1/test/jasper_report_template.jasper";

      DataBeanList DataBeanList = new DataBeanList();
      ArrayList<DataBean> dataList = DataBeanList.getDataBeanList();

      JRBeanCollectionDataSource beanColDataSource = new 
         JRBeanCollectionDataSource(dataList);

      Map parameters = new HashMap();

      try {
         JasperFillManager.fillReportToFile( sourceFileName,
            parameters, beanColDataSource);
      } catch (JRException e) {
         e.printStackTrace();
      }
   }
}

As we would be displaying the marks obtained for each subject, POJO needs to be changed. The file C:\tools\jasperreports-5.0.1\test\src\com\tutorialspoint\DataBean.java contents are as given below −

package com.tutorialspoint;

public class DataBean {
   private String subjectName;
   private Integer marks;

   public String getSubjectName() {
      return subjectName;
   }

   public void setSubjectName(String subjectName) {
      this.subjectName = subjectName;
   }

   public Integer getMarks() {
      return marks;
   }

   public void setMarks(Integer marks) {
      this.marks = marks;
   }

}

Even the contents of the file C:\tools\jasperreports-5.0.1\test\src\com\tutorialspoint\DataBeanList.java need to be updated as given below −

package com.tutorialspoint;

import java.util.ArrayList;

public class DataBeanList {
   public ArrayList<DataBean> getDataBeanList() {
      ArrayList<DataBean> dataBeanList = new ArrayList<DataBean>();

      dataBeanList.add(produce("English", 58));
      dataBeanList.add(produce("SocialStudies", 68));
      dataBeanList.add(produce("Maths", 38));
      dataBeanList.add(produce("Hindi", 88));
      dataBeanList.add(produce("Scince", 78));
      
      return dataBeanList;
   }

   /*
    * This method returns a DataBean object, with subjectName ,
    * and marks set in it.
    */
   private DataBean produce(String subjectName, Integer marks) {
      DataBean dataBean = new DataBean();

      dataBean.setSubjectName(subjectName);
      dataBean.setMarks(marks);

      return dataBean;
   }
}
