Graphing data, Python Programming

Assignment Help:
Write a program that will take price data for stocks and print it graphically to the screen. Your program should begin by asking the user for the file name. It should then create a graphics window and plot the date versus price. You may assume that the file has the following format:

"date","close","volume","open","high","low"
"16:00","720.11","1,919,799","720.71","723","716.68"
"2012/12/19","720.1100","1918493.0000","720.7100","723.0000","716.6800"
"2012/12/18","721.0700","3004838.0000","716.6000","729.1000","715.0500"
"2012/12/17","720.7800","3034558.0000","705.5000","738.2800","704.0200"
"2012/12/14","701.9632","2129893.0000","699.1700","707.8200","698.4300"
"2012/12/13","702.7000","3443866.0000","715.9200","716.4750","699.5500"
"2012/12/12","697.5600","2425774.0000","699.2300","703.5100","693.4800"


where the first line describes the columns and each subsequent line of the file describes the stock price on a given day, separated by commas. Note that the historical data (from Nasdaq) lists the information in reverse chronological order, while graphs of financial data always start with the oldest date first. Your graph should have the oldest date on the left, progressing to the newest date on the right.

Hint: You may assume that the price of any stock is positive and below $1000, so, the y-coordinates of your window should between 0 and 1000. You may also assume that you are graphing data from one year. There are at most 52 weeks * 5 business days/week = 260 days per year, so your x-coordinates should range from 0 to 260 (or a bit extra to make it look nice).
