Code Sample

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

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

//create a chart bean
ParetoChart paretoChart1 = new STATBEANS.ParetoChart();

//set the data column names
paretoChart1.setFrequencyVariableName("Count");
paretoChart1.setLabelVariableName("Problem");

//set the display name
paretoChart1.setClassName("Defects");

//rotate the class labels
paretoChart1.setUseDefaultFonts(false);
paretoChart1.setRotateClassLabels(true);

//set new margtins
paretoChart1.setTopMargin(10);
paretoChart1.setBottomMargin(35);

//make the plot bean a listener for changes in the FileDataSource bean
paretoChart1.addDataChangeListener(fileDataSource1.listenerForDataChange);

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