what if I return a new CategoryDataset object incase there are NO readings to be plotted but I still need to see empty chart.
Will this be an issue ?

oops... there is another class that you need. import java.io.IOException; import java.text.SimpleDateFormat; import java.util.Iterator; import java.util.Vector; public class WSNUtil { /** * * @param v * @return */ public static Boolean[] vectorToBoolean(Vector v) { Boolean[] arr = new Boolean[v.size...

Hello, Given below is code of the 2 classes being used. The output image for both the methods is coming out different. I am unable to figure out why? Please suggest. Thanks, Kanishk import java.awt.Color; import java.awt.Font; import java.awt.image.BufferedImage; import java.io.File; import java.io....

excellent !! that worked like a charm.
Thanks.

Hello, Given below is the code and image generated. My problem is that I don't want the lines to be black but ONLY the data points. Any suggestions? Also, is it possible to put the value above the plotted data points in the graph ? public class MyRenderer extends LineAndShapeRenderer { private Boole...

I am not sure how will this work when using XY chart? I tried using skunk's code and it painted the line AND the dot as BLACK..where as I wanted ONLY the dot to be black. here is the code... public class MyRenderer extends LineAndShapeRenderer { private Boolean[] anomaly; /** * * */ public MyRendere...

I created a subclass to override this method.
public Paint getItemPaint(int series, int item)

BUT, what do I write in the code body to give the functionality?

I have apparently only 1 series and all I want is that points with value below 50 should be filled with black, else white.

I am trying to create a XYLine graph where values less that 50 should be filled with black colour and rest red. JFreeChart chart = ChartFactory.createLineChart( "Reading Status for MOTE# " + moteId, // chart title "Date/Time", // x axis label "Reading", // y axis label getDataset(reading), // data P...

Thank you. :D Hey.. Can you please shed some light on how to override this method? this is the code snippet for my renderer. LineAndShapeRenderer renderer = (LineAndShapeRenderer) plot .getRenderer(); renderer.setShapesVisible(true); renderer.setDrawOutlines(true); renderer.setUseFillPaint(true); r...
