Graphics on Python using PyLab

Some screenshoot below was taken from my Mac. You may wonder ‘Hey, we render in python using Matplotlib, did’nt we?’. Yeah, pylab is part of matplotlib, so, have fun…

from pylab import grid, xlabel, ylabel, title, plot, ylim, xlim, show, sin, cos
r=10
x=[]
y=[]
n=19
for i in range(n):
 y.append([])
 x.append([])
 y[i].append(0)
 x[i].append(0)
for i in range(n):
 phi=7*i
 y[i].append(r*sin(phi))
 x[i].append(r*cos(phi))
grid(True)
xlabel('Sumbu x')
ylabel('Sumbu y')
title('Jejak ')
plot(x[0],y[0],'b-',x[1],y[1],'g-',
 x[2],y[2],'r-',x[3],y[3],'b-',x[4],y[4],'r-')
batas=10
ylim(-batas,batas)
xlim(-batas,batas)
show()

from pylab import grid, xlabel, ylabel, title, plot, ylim, xlim, show, sin
from visual import *
x=[]
x=arange(-10.,10.,0.1)
grid(True)
xlabel('Sumbu x')
ylabel('Sumbu y')
title('Jejak ')
plot(x,sin(x),'b-')
batas=10
ylim(-2,2)
xlim(-batas,batas)
show()
