You can use a RescaleOp. Check out this tutorial.

is there any other help...........

Why, did you find RescaleOp unsuitable for your purpose?

OK I will try something for sure but right now first i am trying to plot histogram of an image so suggest me that how could i plot my histogram in a JPanel or content pane.
I got the the histogram using Jai now need to plot it somehow

Here is how i am getting my histogram

PlanarImage image = JAI.create("fileload", "C:\\Sunset.jpg");
ParameterBlock pb = new ParameterBlock();
pb.addSource(image);
pb.add(null); // The ROI.
pb.add(1); // Samplings.
pb.add(1);
pb.add(new int[]{256}); // Num. bins.
pb.add(new double[]{0}); // Min value to be considered.
pb.add(new double[]{256}); // Max value to be considered.
// Creates the histogram.
PlanarImage temp = JAI.create("histogram", pb);
Histogram h = (Histogram)temp.getProperty("histogram");

> how could i plot my histogram in a JPanel or content pane.

Yes Michael, I can plot it using ImajeJ library but the thing is i need to have my own histogram so that i can be helpful to me in my further image processing
so suggest me some way to plot it

> so suggest me some way to plot it

I did.

unless you're the only person to have ever wanted to plot a histogram in java,
there should be heaps of sample code out there.

grab some of the code, modify to suit, then, if you have problems,
you can post the code you've tried.

if you're waiting for someone to write it for you, there's rent-a-coder for that
