Code Sample

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

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

//set the delimiter character used in the file
fileDataSource1.setDelimiter("tab");

//create a calculation bean
GageRandR gageRandR1 = new STATBEANS.GageRandR();

//set the column names
gageRandR1.setOperatorVariableName("Operator");
gageRandR1.setPartVariableName("Part");
String temp[]=new String[2];
temp[0]="Measure1";
temp[1]="Measure2";
gageRandR1.setMeasurementVariableNames(temp);

//set the method type
gageRandR1.setMethod("ANOVA");

//create a table bean
GageRandRTable gageTable1 = new STATBEANS.GageRandRTable();
gageTable1.setBackground(Color.yellow);
gageTable1.setBounds(10,30,560,320);

//create a plot bean
GageRandRPlot gagePlot1 = new STATBEANS.GageRandRPlot();
gagePlot1.setBounds(10,350,560,200);

//add the table and plot to the application frame
add(gageTable1);
add(gagePlot1);

//make the calculation bean a listener for changes in the FileDataSource bean
fileDataSource1.addDataChangeListener(gageRandR1.listenerForDataChange);

//make the table and plot beans listeners for changes in the calculation bean
gageRandR1.addDataChangeListener(gageTable1.listenerForDataChange);
gageRandR1.addDataChangeListener(gagePlot1.listenerForDataChange);

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