Periodogram Analysis Code Sample

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

//set the file name to be read 
//create a plot bean 

PeriodogramPlot plot1 = new STATBEANS.PeriodogramPlot(); 
//set the variable names for plotting 


//add the plot to the application frame 

//make the plot bean a listener for changes in the FileDataSource bean 

//instruct the fileDataSource bean to read the file
