Example pygame programs

• event_loop.py
• circle.py
• square.py
• square_filled.py

Useful Functions

• You may find strings2points() and splitUp() from Homework 6 to be useful in completing this assignment.

Line Graphs

• Your top-level function will be called renderData(). It should take a filename as a parameter:

  def renderData(filename):
  

• The filename will correspond to a file generated by the d2file function from Homework 9
• You will need to alter the points read in from the file to fit the window width and height:
  • The graphics functions expect all points to be lists of tuples. Hence, when you read in data from the file, it will need to be put in that form.
  • Plot each point as a filled-in circle. Also plot a line between each consecutive pair of points.
  • At first, just try plotting the points without alteration, in order to get a sense of what must be done to make them look right.
  • If the graph is too small, it will need to be stretched to fit the viewing window. If it is too large, it will need to be compressed to fit the viewing window. Hint: Both stretching and compressing of points can be expressed using the same calculation. Find the minimum and maximum of each of the x- and y-coordinates, and employ those values in scaling the points.
  • Be careful with the y-coordinates; you do not want your graph to be upside-down.
  • The program should display the graph until the user closes the window.
