TimeSeriesForecastPlot Statbean®



Purpose: Plots forecast for a time series. Allows Statgraphics to create a time series forecasting model.

Time Series Visualization DataSource: TimeSeriesForecast. 

forecastplot


Time Series Visualization Read/Write Properties
Name Type Description Possible Values Default Value
confidenceLimitsColor Color The color of the confidence limits. Any valid Color. Color.red
forecastColor Color The color of the forecasts. Any valid Color. Color.magenta
lastPeriodsToPlot int The number of data values to plot in addition to the forecasts. 0+, or -1 for all -1
showConfidenceLimits boolean Whether to display confidence limits for the forecasts. true,false true

Other properties for creating a time series forecasting model are inherited from the java.awt.Canvas class and from the general GraphicalStatbean class.

Time Series Visualization Tool Code Sample 

//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();
