XYPlot STATBEAN®

Other properties needed for the scatter plot graph maker are inherited from the java.awt.Canvas class and from the general GraphicalStatbean class.

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"); 

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

//create a plot bean 
XYPlot xYPlot1 = new STATBEANS.XYPlot(); 

//set the columns for the x and y axes 
xYPlot1.setYVariableName("mpg"); 
xYPlot1.setXVariableName("weight"); 

//override default scaling 
xYPlot1.setUseDefaultScaling(false); 

//set scaling for x-axis 
xYPlot1.setXaxisFrom(1500.0); 
xYPlot1.setXaxisTo(4500.0); 
xYPlot1.setXaxisBy(1000.0); 

//set scaling for y-axis 
xYPlot1.setYaxisFrom(10.0); 
xYPlot1.setYaxisTo(50.0); 
xYPlot1.setYaxisBy(10.0); 

//add a smoother 
xYPlot1.setSmootherType("Robust LOWESS"); 

//override the top title 
xYPlot1.setTopTitleLine1("Plot of Automobile Data"); 

//override the xaxis title 
xYPlot1.setXaxisTitle("weight in pounds"); 

//turn on point identifcation 
xYPlot1.setHighlightPointOnMouseClick(true); 
xYPlot1.setShowPointClickedMessage(true); 

//add the plot to the application frame 
add(xYPlot1); 

//make the plot a listener for changes in the FileDataSource bean 
fileDataSource1.addDataChangeListener(xYPlot1.listenerForDataChange); 

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