//create a datasource bean 
FileDataSource fileDataSource1 = new STATBEANS.FileDataSource(); 

//set the file name to be read 
fileDataSource1.setFileName("c:\\statbeans\\samples\\cardata.txt"); 

//create a chart bean 
FactorBoxPlot plot1 = new STATBEANS.FactorBoxPlot(); 
plot1.setBackground(java.awt.Color.yellow); 
plot1.setBounds(16,30,380,300); 

//set the column to be plotted 
plot1.setXVariableName("mpg"); 

//set the factor column 
plot1.setFactorVariableName("year"); 

//set the direction 
plot1.setDrawVertical(true); 

//show the plot 
add(plot1); 

//make the plot bean a listener for changes in the FileDataSource bean 
fileDataSource1.addDataChangeListener(plot1.listenerForDataChange); 

//instruct the fileDataSource bean to read the file
