image not displayed on the frame

[vy_007]

I want to print the histogram of an image in the same window. The given code works fine with viewing the histogram through Windows Image Viewer(default program) but fails to print the required histogram and image in a frame.

# RGB Hitogram
# This script will create a histogram image based on the RGB content of
# an image. It uses PIL to do most of the donkey work but then we just
# draw a pretty graph out of it.
#
# 
#

import ImageDraw
from Tkinter import *
from PIL import ImageTk, Image

root=Tk()

def show(root,filename):
 imagepath = filename  # The image to build the histogram of


 histHeight = 120            # Height of the histogram
 histWidth = 256             # Width of the histogram
 multiplerValue = 1.5        # The multiplier value basically increases
                            # the histogram height so that love values
                            # are easier to see, this in effect chops off
                            # the top of the histogram.
 showFstopLines = True       # True/False to hide outline
 fStopLines = 5


 # Colours to be used
 backgroundColor = (51,51,51)    # Background color
 lineColor = (102,102,102)       # Line color of fStop Markers 
 red = (255,60,60)               # Color for the red lines
 green = (51,204,51)             # Color for the green lines
 blue = (0,102,255)              # Color for the blue lines

 # Now save and show the histogram
