Hi all,

I am displaying image histograms on a user interface. Each histogram is represented by a class I wrote which extends JComponent. The painting is done the proper way through paintComponent and repaint() and it works great.

In my GUI constructor, I display the histograms..



And whenever I change the image, I call an update() method that contains the following line of code to update the histograms:

[code] graphs = plotter.plotRGB(currentImage); // Create histograms
