The Column Chart Applet example.

This example produces a chart of fictitious Sales of three products for the 4 quarters of the year. This example demonstrates many of the features of the Column Chart Bean including, multiple series, automatic legend generation, bespoke chart notes, the 3D effects and bespoke images.

The full source code for this example can be found in the ColumnechartApplet directory,

./ColumnchartApplet/ColumnchartApplet.java

To see the applet working simply open the file ./ColumnchartApplet/columnchart.htm in a browser or the appletviewer.

You should now see the following,

Step 1 - Create the Basic Applet Framework.

The first thing to do is to create a basic applet framework which imports all the necessary classes and create a Window and Frame.

import Sirius.columnchart.*;
import java.applet.Applet;
import java.awt.*;
import java.util.*;
import java.awt.image.*;
import java.net.*;
import java.lang.*;

public class ColumnchartApplet extends Applet
{

    public ColumnchartApplet()
    {
    }

    public void init()
    {
        setLayout(null);
        setBackground(Color.white);
    }


//----------------------------------------------------------------------------------
} // End Applet class 
 
Step 2 - Add in and initialise the Columnchart Bean.
In this step we declare the Columnchart object ( columnchart ) and create and instance
of the Columnchart Bean. Following this the columnchart canvas is resized and then added
to the applet frame.

import Sirius.columnchart.*;
import java.applet.Applet;
import java.awt.*;
import java.util.*;
import java.awt.image.*;
import java.net.*;
import java.lang.*;

public class ColumnchartApplet extends Applet
{
    // Bean Object
    private Columnchart columnchart;

    public ColumnchartApplet()
    {
    }

    public void init()
    {
        columnchart = new Columnchart();
        columnchart.resize(500,420);

        setLayout(null);
        setBackground(Color.white);
        add(columnchart);
    }


//----------------------------------------------------------------------------------
} // End Applet class 



Step 3 - Create the Text data object and set this property of the Column Chart Bean.

Pay particular attention to the set_textdata method. This is where the three elements 
of text are created and added to the text data object. Finally in this method the 
Textdata property of the Columnchart bean is set with the column, columnchart.setTextdata(textdata);



import Sirius.columnchart.*;
import java.applet.Applet;
import java.awt.*;
import java.util.*;
import java.awt.image.*;
import java.net.*;
import java.lang.*;

public class ColumnchartApplet extends Applet
{
    // Bean Object
    private Columnchart columnchart;

    // Data Objects
    private Vector textdata;    // Text Objects

    public ColumnchartApplet()
    {
    }

    public void init()
    {
        columnchart = new Columnchart();
        columnchart.resize(500,420);

        set_textdata();

        setLayout(null);
        setBackground(Color.white);
        add(columnchart);
    }

//-----------------------------------------------------------------------------
// Create the text object
//
    private void set_textdata() {
       textdata = new Vector();
       textdata.addElement(new Textdata("Note:",                           // Text line 1
                                        new Color(0,0,255),                // text color
                                        new Font("TimesRoman",Font.PLAIN,12),  // text font
                                        new Point(80,60)                   // text position (x,y)
                                        ));
       textdata.addElement(new Textdata("New product range",               // Text line 2
                                        new Color(0,0,0),                  // text color
                                        new Font("TimesRoman",Font.PLAIN,12), // text font
                                        new Point(80,80)                   // text position (x,y)
                                        ));
       textdata.addElement(new Textdata("launched during",                 // Text line 3
                                        new Color(0,0,0),                  // text color
                                        new Font("TimesRoman",Font.PLAIN,12), // text font
                                        new Point(80,100)                  // text position (x,y)
                                        ));
       textdata.addElement(new Textdata("quarter 2.",                      // Text line 3
                                        new Color(0,0,0),                  // text color
                                        new Font("TimesRoman",Font.PLAIN,12), // text font
                                        new Point(80,120)                  // text position (x,y)
                                        ));

       columnchart.setTextdata(textdata);
	}
//----------------------------------------------------------------------------------
} // End Applet class 





Step 4 - Create the Title data object and set this property of the Column Chart Bean.

Pay particular attention to the set_titledata method. This is where the three elements 
representing the titles are created and added to the title data object. Finally in this method the 
Titledata property of the Columnchart bean is set with the column, columnchart.setTitledata(textdata);

import Sirius.columnchart.*;
import java.applet.Applet;
import java.awt.*;
import java.util.*;
import java.awt.image.*;
import java.net.*;
import java.lang.*;

public class ColumnchartApplet extends Applet
{
    // Bean Object
    private Columnchart columnchart;

    // Data Objects
    private Vector textdata;    // Text Objects
    private Vector titledata;   // Title Objects (Main Title, X Title, Y Title)

    public ColumnchartApplet()
    {
    }

    public void init()
    {
        columnchart = new Columnchart();
        columnchart.resize(500,420);

        set_textdata();
        set_titledata();

        setLayout(null);
        setBackground(Color.white);
        add(columnchart);
    }

//-----------------------------------------------------------------------------
// Create the text object
//
    private void set_textdata() {
       textdata = new Vector();
       textdata.addElement(new Textdata("Note:",                           // Text line 1
                                        new Color(0,0,255),                // text color

                                        ));
       textdata.addElement(new Textdata("New product range",               // Text line 2
                                        new Color(0,0,0),                  // text color
                                        new Font("TimesRoman",Font.PLAIN,12), // text font
                                        new Point(80,80)                   // text position (x,y)
                                        ));
       textdata.addElement(new Textdata("launched during",                 // Text line 3
                                        new Color(0,0,0),                  // text color
                                        new Font("TimesRoman",Font.PLAIN,12), // text font
                                        new Point(80,100)                  // text position (x,y)
                                        ));
       textdata.addElement(new Textdata("quarter 2.",                      // Text line 3
                                        new Color(0,0,0),                  // text color
                                        new Font("TimesRoman",Font.PLAIN,12), // text font
                                        new Point(80,120)                  // text position (x,y)
                                        ));

       columnchart.setTextdata(textdata);
	}
//-----------------------------------------------------------------------------
// Create the  titledata object
//
    private void set_titledata() {
       titledata = new Vector();
       titledata.addElement(new Titledata("Sales by Quarter",new Color(100,100,100),new Font("TimesRoman",Font.BOLD + Font.ITALIC,18),new Point(50,20)));
       titledata.addElement(new Titledata("Year 2001",new Color(100,100,100),new Font("TimesRoman",Font.BOLD,16),new Point(200,400)));
       titledata.addElement(new Titledata("Value $",new Color(100,100,100),new Font("TimesRoman",Font.BOLD,16),new Point(10,300)));
       columnchart.setTitledata(titledata);
	}

//----------------------------------------------------------------------------------
} // End Applet class 



Step 5 - Create the X axis Labels data object and set this property of the Column Chart Bean.

Pay particular attention to the set_xlabelsdata method. Here the twelve labels representing the 
months of the year are created. Finally in this method the Xlabelsdata property of the Columnchart bean is set with the column, columnchart.setXlabelsdata(xlabelsdata);

                                        ));
       textdata.addElement(new Textdata("quarter 2.",                      // Text line 3

       columnchart.setTextdata(textdata);
	}

//-----------------------------------------------------------------------------
// Create the  titledata object

    private void set_xlabelsdata() {
       xlabelsdata = new Vector();
       xlabelsdata.addElement(new Xlabelsdata("Quarter 1",new Color(0,0,0),new Font("TimesRoman",Font.PLAIN,10), 375, 0));
       xlabelsdata.addElement(new Xlabelsdata("Quarter 2",new Color(0,0,0),new Font("TimesRoman",Font.PLAIN,10), 375, 0));
       xlabelsdata.addElement(new Xlabelsdata("Quarter 3",new Color(0,0,0),new Font("TimesRoman",Font.PLAIN,10), 375, 0));

       columnchart.setXlabelsdata(xlabelsdata);
	}

//----------------------------------------------------------------------------------
} // End Applet class 




Step 6 - Create the Y axis Labels data object and set this property of the Column Chart Bean.

Pay particular attention to the set_ylabelsdata method. Only one element is added to this 
object and the bean will only ever use the first element. Finally in this method the 
Ylabelsdata property of the Columnchart bean is set with the column, columnchart.setYlabelsdata(ylabelsdata);

	}

//-----------------------------------------------------------------------------
// Create the xlabels object

Step 7 - Create the Column and Series data objects and set this property of the Column Chart Bean.

Here we create the Column and Series data objects, notice how the Column data object becomes part of 
the series data object. Finally in this method the Seriesdata property of the Columnchart bean is 
set with the column, columnchart.setSeriesdata(seriesdata);

Step 10 - Create the Image data object and set this property of the Column Chart Bean.

Here we create Image data object with the method set_imagedata(). We create three elements for this object 
which represent the three product images dispayed on the chart canvas. This method
uses the DownloadImage method to load the images from file. Finally in this method the Imagedata property
of the Columnchart bean is set with the column, columnchart.seImagedata(imagedata);

Step 11 - Create the MinMax data object and set this property of the Column Chart Bean.

Here we create MinMax data object with the method set_minmaxdata(). We create two elements for this object 
which represent the Break Even and Target columns on our our Sale chart. Finally in this method the 
data property of the Columnchart bean is set with the column, columnchart.setMinmaxdata(minmaxdata);

Summary

In order to generate the column chart within an applet a simple applet framework was created, an instance of the columnchart bean was created and finally the data objects were created and the corresponding bean properties set.
