Update Jfreechart when update data from Webcam - jfreechart

Question

My jfreeChart comes from frames of a webcam. I pass this frames and it generates a graphic of R, G and B colors of this frame. I want this chart do automatic update as I pass the frames. I've tried everything but nothing seens to work.
Any help is welcome.

Imgcodecs.imencode(".bmp", frame, mem);
Image im = ImageIO.read(new ByteArrayInputStream(mem.toArray()));
buff = (BufferedImage) im;
if(contHistograma==0) {
h = new Histo(buff);
contHistograma++;
}else{
h.update(buff);
}
webcamLabel.setIcon(new ImageIcon(buff));
Graphics g=webcamPanel.getGraphics();
if (g.drawImage(buff, 0, 0, getWidth(), getHeight() -150 , 0, 0, buff.getWidth(), buff.getHeight(), null))

Answer 1

If someone else have this problem here is the answer:
Chartframe can't get rid of chartpanel, so I made Chartpanel a atribute.
After that I update my dataset and did this:
JFreeChart chart = createChart(dataset);
chartPanel.setChart(chart);
lineFrame.setLayout(new BorderLayout());
lineFrame.repaint();
Problem solved.
