Perlin noise plot graphic

Hi!!
I wrote this little code to plot a updated graphic of a Perlin noise in a 720x240 window , this is done
by shiftting the plot to left side of the window each second; but the plot is updated only when I minimize
and again maximize the window. Where is my mistake? Can someone help me?
Thanks, planctum.
