We have no knowledge of your color constancy program so we can't say why it will not display. In a regular MATLAB program with an axes, you'd do something like this:
[pixelCounts grayLevels] = imhist(grayImage, 256);
bar(grayLevels, pixelCounts, 'BarWidth', 1.0);
but that's for a gray scale image, not a color image. I also don't know what an "error ration" is. Finally, explain how you got the gray level image from the "original" image.
