Yeah, I agree. If you represent the histogram as bar graph with a 1 pixel
line for each value then the graph would be many many screens wide.

That's not the only way to represent the information though. What if,
instead of the height of a line, you used a gray scale value to represent
the number of pixels at a given position (white for none, black for max
count). Then you could represent your histogram as an image, giving one
pixel of the "histogram image" to each of your 64K values. You could display
all that data in a 256x256 pixel square, something you could easily see
onscreen. Any white pixels in the "histogram image" would be the "gaps" in
your histogram. I think that would give you a manageable way of presenting
the data in a format that you could still interpret and get some value from.

Jason,

You are right about the number of pixels to measure but I was
thinking about drawing the on screen representation with 65,000
individual bars in the bar graph as opposed to 256. Still might be
trival in terms of the actual computing power required I have to
admit.
