How to use python programming to make graphing xy charts?

Answer 1

try using this code:

import pygame

def main():

(tab)screen = pygame.display.set_mode((750,750))

(tab)pygame.display.set_caption("graph")

(tab)screen.fill((255,255,255))

(tab)pygame.draw.line(screen, (0, 0, 0), (375, 0), (375, 750))

(tab)pygame.draw.line(screen, (0, 0, 0), (0, 375), (750, 375))

(tab)pygame.display.flip()

(tab)while True:

(tab)(tab)x = raw_input("x: ")

(tab)(tab)if x 'q':

(tab)(tab)(tab)pygame.quit()

(tab)(tab)(tab)break

(tab)(tab)print ''

(tab)(tab)screen.fill((255,255,255))

(tab)(tab)pygame.draw.line(screen, (0, 0, 0), (375, 0), (375, 750))

(tab)(tab)pygame.draw.line(screen, (0, 0, 0), (0, 375), (750, 375))

(tab)(tab)try:

(tab)(tab)(tab)pygame.draw.circle(screen, (0, 0, 255), (int(x) + 375, -1 * int(y) + 375), 3 )

(tab)(tab)except:

(tab)(tab)(tab)print "graph error, please enter valid x,y coordinates"

(tab)(tab)pygame.display.flip()

main()

pygame.quit()

this code makes a simple grapher.unfortunitly when I typed this answer, the tabs don't show up so I had to do this instead. any time it says "(tab)" just insert a tab there instead.
