Help required with Tranformation of coordinate system
hi all! i need a help in python! i am struggling to implement this since last 2/3 days. suppose i have a 2D plot (say y=x**2). now on the same plot i want to transform my origin of coordinate system to a point (x',y' on this curve and again create a new plot with origin at x',y') can somebody help me how can i offset my cordinate system ... -- http://mail.python.org/mailman/listinfo/python-list

THanks again, hope i made myself clear :) -- http://mail.python.org/mailman/listinfo/python-list
