Code Sample

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

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

//create a chart bean
ProbabilityPlot probabilityplot1 = new STATBEANS.ProbabilityPlot();

//set the column to be plotted
probabilityplot1.setXVariableName("strength");

//define the plot type
probabilityplot1.setDistribution("Normal");

//show the plot
add(probabilityplot1);

//make the plot bean a listener for changes in the FileDataSource bean
fileDataSource1.addDataChangeListener(probabilityplot1.listenerForDataChange);

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