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

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

//create a forecasting bean
TimeSeriesForecast forecast1 = new STATBEANS.TimeSeriesForecast();

//set variable name
forecast1.setTimeSeriesVariableName("traffic");

//set time scale
forecast1.setTimeScale("month");
forecast1.setStartTime("1/86");
forecast1.setSeasonalLength(12);

//set number of forecasts desired
forecast1.setNumberOfForecasts(24);

//set model type and parameters
forecast1.setModelType("ARIMA");
forecast1.setArimaD(1);
forecast1.setArimaMA(1);
forecast1.setArimaSD(1);
forecast1.setArimaSMA(1);
forecast1.setArimaIncludeConstant(false);

//create a plot bean
TimeSeriesForecastPlot plot1 = new STATBEANS.TimeSeriesForecastPlot();

//set plot features
plot1.setBounds(36,12,450,300);
plot1.setHighlightPointOnMouseClick(true);
plot1.setShowPointClickedMessage(true);

//restrict amount of historical data plotted
plot1.setLastPeriodsToPlot(120);

//add the plot to the application frame
add(plot1);

//make the forecasting bean a listener for changes in the FileDataSource bean
fileDataSource1.addDataChangeListener(forecast1.listenerForDataChange);

//make the plot bean a listener for changes in the forecasting bean
forecast1.addDataChangeListener(plot1.listenerForDataChange);

//instruct the fileDataSource bean to read the file
fileDataSource1.readData();
