GWT Highcharts – Configuration Syntax ”; Previous Next In this chapter, we will showcase the configuration required to draw a chart using the Highcharts API in GWT. Step 1: Create GWT Application Follow the following steps to update the GWT application we created in GWT – Create Application chapter − Step Description 1 Create a project with a name HelloWorld under a package com.tutorialspoint as explained in the GWT – Create Application chapter. 2 Modify HelloWorld.gwt.xml, HelloWorld.html and HelloWorld.java as explained below. Keep rest of the files unchanged. 3 Compile and run the application to verify the result of the implemented logic. Following is the content of the modified module descriptor src/com.tutorialspoint/HelloWorld.gwt.xml. <?xml version = “1.0” encoding = “UTF-8″?> <module rename-to = ”helloworld”> <inherits name = ”com.google.gwt.user.User”/> <inherits name = ”com.google.gwt.user.theme.clean.Clean”/> <entry-point class = ”com.tutorialspoint.client.HelloWorld”/> <inherits name=”org.moxieapps.gwt.highcharts.Highcharts”/> <source path = ”client”/> <source path = ”shared”/> </module> Following is the content of the modified HTML host file war/HelloWorld.html. <html> <head> <title>GWT Highcharts Showcase</title> <link rel = “stylesheet” href = “HelloWorld.css”/> <script language = “javascript” src = “helloworld/helloworld.nocache.js”> <script src = “https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js” /> <script src = “https://code.highcharts.com/highcharts.js” /> </script> </head> <body> </body> </html> We”ll see the updated HelloWorld.java in the end after understanding configurations. Step 2: Create Configurations Create Chart Configure the type, title and sub-title of the chart. Chart chart = new Chart() .setType(Type.SPLINE) .setChartTitleText(“Monthly Average Temperature”) .setChartSubtitleText(“Source: WorldClimate.com”); xAxis Configure the ticker to be displayed on the X-Axis. XAxis xAxis = chart.getXAxis(); xAxis.setCategories(“Jan”, “Feb”, “Mar”, “Apr”, “May”, “Jun”, “Jul”, “Aug”, “Sep”, “Oct”, “Nov”, “Dec”); yAxis Configure the title, plot lines to be displayed on the Y-Axis. YAxis yAxis = chart.getYAxis(); yAxis.setAxisTitleText(“Temperature °C”); yAxis.createPlotLine() .setValue(0) .setWidth(1) .setColor(“#808080”); tooltip Configure the tooltip. Put suffix to be added after value (y-axis). ToolTip toolTip = new ToolTip(); toolTip.setValueSuffix(“°C”); chart.setToolTip(toolTip); legend Configure the legend to be displayed on the right side of the chart along with other properties. legend.setLayout(Legend.Layout.VERTICAL) .setAlign(Legend.Align.RIGHT) .setVerticalAlign(Legend.VerticalAlign.TOP) .setX(-10) .setY(100) .setBorderWidth(0); chart.setLegend(legend); series Configure the data to be displayed on the chart. Series is an array where each element of this array represents a single line on the chart. chart.addSeries(chart.createSeries() .setName(“Tokyo”) .setPoints(new Number[] { 7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6 }) ); chart.addSeries(chart.createSeries() .setName(“New York”) .setPoints(new Number[] { -0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5 }) ); chart.addSeries(chart.createSeries() .setName(“Berlin”) .setPoints(new Number[] { -0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0 }) ); chart.addSeries(chart.createSeries() .setName(“London”) .setPoints(new Number[] { 3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8 }) ); Step 3: Add the chart to parent panel. We”re adding the chart to root panel. RootPanel.get().add(chart); Example Consider the following example to further understand the Configuration Syntax − HelloWorld.java package com.tutorialspoint.client; import org.moxieapps.gwt.highcharts.client.Chart; import org.moxieapps.gwt.highcharts.client.Legend; import org.moxieapps.gwt.highcharts.client.Series.Type; import org.moxieapps.gwt.highcharts.client.ToolTip; import org.moxieapps.gwt.highcharts.client.XAxis; import org.moxieapps.gwt.highcharts.client.YAxis; import com.google.gwt.core.client.EntryPoint; import com.google.gwt.user.client.ui.RootPanel; public class HelloWorld implements EntryPoint { public void onModuleLoad() { Chart chart = new Chart() .setType(Type.SPLINE) .setChartTitleText(“Monthly Average Temperature”) .setChartSubtitleText(“Source: WorldClimate.com”); XAxis xAxis = chart.getXAxis(); xAxis.setCategories(“Jan”, “Feb”, “Mar”, “Apr”, “May”, “Jun”, “Jul”, “Aug”, “Sep”, “Oct”, “Nov”, “Dec”); YAxis yAxis = chart.getYAxis(); yAxis.setAxisTitleText(“Temperature °C”); yAxis.createPlotLine() .setValue(0) .setWidth(1) .setColor(“#808080”); ToolTip toolTip = new ToolTip(); toolTip.setValueSuffix(“°C”); chart.setToolTip(toolTip); Legend legend = new Legend(); legend.setLayout(Legend.Layout.VERTICAL) .setAlign(Legend.Align.RIGHT) .setVerticalAlign(Legend.VerticalAlign.TOP) .setX(-10) .setY(100) .setBorderWidth(0); chart.setLegend(legend); chart.addSeries(chart.createSeries() .setName(“Tokyo”) .setPoints(new Number[] { 7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6 }) ); chart.addSeries(chart.createSeries() .setName(“New York”) .setPoints(new Number[] { -0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5 }) ); chart.addSeries(chart.createSeries() .setName(“Berlin”) .setPoints(new Number[] { -0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0 }) ); chart.addSeries(chart.createSeries() .setName(“London”) .setPoints(new Number[] { 3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8 }) ); RootPanel.get().add(chart); } } Result Verify the result.

GWT Highcharts – Environment Setup ”; Previous Next This tutorial will guide you on how to prepare a development environment to start your work with Highcharts and GWT Framework. This tutorial will also teach you how to setup JDK, Tomcat and Eclipse on your machine before you setup GWT Framework − System Requirement GWT requires JDK 1.6 or higher so the very first requirement is to have JDK installed in your machine. JDK 1.6 or above. Memory no minimum requirement. Disk Space no minimum requirement. Operating System no minimum requirement. Follow the given steps to setup your environment to start with GWT application development. Step 1 – Verify Java Installation on your Machine Now open console and execute the following java command. OS Task Command Windows Open Command Console c:> java -version Linux Open Command Terminal $ java -version Mac Open Terminal machine:~ joseph$ java -version Let”s verify the output for all the operating systems Sr.No. OS & Generated Output 1 Windows java version “1.6.0_21” Java(TM) SE Runtime Environment (build 1.6.0_21-b07) Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing) 2 Linux java version “1.6.0_21” Java(TM) SE Runtime Environment (build 1.6.0_21-b07) ava HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing) 3 Mac java version “1.6.0_21” Java(TM) SE Runtime Environment (build 1.6.0_21-b07) Java HotSpot(TM)64-Bit Server VM (build 17.0-b17, mixed mode, sharing) Step 2 – Setup Java Development Kit (JDK) If you do not have Java installed then you can install the Java Software Development Kit (SDK) from Oracle”s Java site: Java SE Downloads. You will find instructions for installing JDK in downloaded files, follow the given instructions to install and configure the setup. Finally set PATH and JAVA_HOME environment variables to refer to the directory that contains java and javac, typically java_install_dir/bin and java_install_dir respectively. Set the JAVA_HOME environment variable to point to the base directory location where Java is installed on your machine. For example Sr.No. OS & Output 1 Windows Set the environment variable JAVA_HOME to C:Program FilesJavajdk1.6.0_21 2 Linux export JAVA_HOME = /usr/local/java-current 3 Mac export JAVA_HOME = /Library/Java/Home Append Java compiler location to System Path. Sr.No. OS & Output 1 Windows Append the string ;%JAVA_HOME%bin to the end of the system variable, Path. 2 Linux export PATH=$PATH:$JAVA_HOME/bin/ 3 Mac not required Alternatively, if you use an Integrated Development Environment (IDE) like Borland JBuilder, Eclipse, IntelliJ IDEA, or Sun ONE Studio, compile and run a simple program to confirm that the IDE knows where you installed Java, otherwise do proper setup as given document of the IDE. Step 3 – Setup Eclipse IDE All the examples in this tutorial have been written using Eclipse IDE. So I would suggest you should have latest version of Eclipse installed on your machine based on your operating system. To install Eclipse IDE, download the latest Eclipse binaries from https://www.eclipse.org/downloads/. Once you downloaded the installation, unpack the binary distribution into a convenient location. For example in C:eclipse on windows, or /usr/local/eclipse on Linux/Unix and finally set PATH variable appropriately. Eclipse can be started by executing the following commands on windows machine, or you can simply double click on eclipse.exe %C:eclipseeclipse.exe Eclipse can be started by executing the following commands on Unix (Solaris, Linux, etc.) machine − $/usr/local/eclipse/eclipse After a successful startup, if everything is fine then it should display following result − Step 4: Install GWT SDK & Plugin for Eclipse Follow the instructions given at the link Plugin for Eclipse (incl. SDKs) to install GWT SDK & Plugin for Eclipse version installed on your machine. After a successful setup for the GWT plugin, if everything is fine then it should display following screen with Google icon marked with red rectangle as shown below − Step 5: Install Highcharts Download the latest Highcharts jar from its Downloadpage and add it to project”s classpath. Add the following entry in <project-name>.gwt.xml file <inherits name=”org.moxieapps.gwt.highcharts.Highcharts”/> Add the following entry in <project-name>.html file <script src = “https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js”/> <script src = “https://code.highcharts.com/highcharts.js”/> <script type=”text/javascript” src=”https://code.highcharts.com/highcharts-3d.js” /> <script type=”text/javascript” src=”https://code.highcharts.com/highcharts-more.js” /> <script src = “https://code.highcharts.com/modules/heatmap.js” /> <script src = “https://code.highcharts.com/modules/treemap.js” /> Print Page Previous Next Advertisements ”;
