Animated plots. Write a program that takes a command-line argument m and produces a bar graph of the m most recent double values on standard input. Use the same animation technique that we used for Bouncing Ball (PROGRAM 1.5.6): erase, redraw, show, and wait briefly. Each time your program reads a new number, it should redraw the whole bar graph. Since most of the picture does not change as it is redrawn slightly to the left, your program will produce the effect of a fixed-size window dynamically sliding over the input values. Use your program to plot a huge time-variant data file, such as stock prices.
