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
String xnames[]=new String[1];
xnames[0]="weight";
String ynames[]=new String[2];
ynames[0]="mpg";
ynames[1]="displace";
xYPlot1.setXVariableNames(xnames);
xYPlot1.setYVariableNames(ynames);

//set the point types and color
String ptype[]={"triangle","square"};
xYPlot1.setPointTypes(ptype);
Color pcolor[]={Color.blue,Color.green};
xYPlot1.setPointColors(pcolor);

//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();
