Hi, I have some two sets of data with their x and ycoordinates, (x1, y1) and (x2, y2). I want to plot these curves as a parametric plot: ######### from numpy import * from pylab import * t = arange (0.0 , pi/2 , 0.05) x1= cos(t) y1 = sin(t) x2 = 1+2/pi*t y2 = 2/pi*t # plotted as a normal plot plot( t , x1 , t , y1 ,t , x2, t , y2) legend(('x1','y1','x2','y2')) show() ######### I have read that this is done with the countour function, but I cannot figure out how. Can somebody help me. Also I have tried to search for information in this forum using the search tool at the top of the page, but I could not get any hit even for obvious queries such as "output". Is there something wrong? Thank you in advance Aitor
