Code Sample

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

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

//create a plot bean
CasementPlot casementPlot1 = new STATBEANS.CasementPlot();

//set the columns names
casementPlot1.setXVariableName("weight");
casementPlot1.setYVariableName("horsepower");
casementPlot1.setZVariableName("mpg");

//add plot
add(casementPlot1);

//make the plot a listener for changes in the FileDataSource bean
fileDataSource1.addDataChangeListener(casementPlot1.listenerForDataChange);

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