Code Sample

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

//set the file name to be read
fileDataSource1.setFileName("c:\\statbeans\\samples\\stocks.txt");
//create a plot bean

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

plot1.setTimeSeriesVariableName("price");

//add the plot to the application frame
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
fileDataSource1.readData();
