Grafik Scatter

from numpy import *

import matplotlib.pyplot as plt

x = linspace(0,2 * pi, 50)

 

plt.scatter(x, sin(x))

plt.show()

Legend

Output:

Membuat Legenda

from numpy import *

import matplotlib.pyplot as plt

x = linspace(0,2 * pi, 50)

#add label in plot command 

#plt.plot(x, sin(x), 'r-^', x, sin(2*x), 'b-o', label = 'sin')

#plt.plot(x,cos(x), label = 'cos')

#plt.legend()

plt.plot(x, sin(x), 'r-^', x, sin(2*x), 'b-o')

plt.plot(x,cos(x))

#as list in legend command

plt.legend(['sin', 'sin', 'cos'])

plt.show()

Output:

Title, label, and Grid

from numpy import *

import matplotlib.pyplot as plt

x = linspace(0,2 * pi, 50)

 

#plt.plot(x, sin(x), 'r-^', x, sin(2*x), 'b-o', label = 'sin')

#plt.plot(x,cos(x), label = 'cos')

#plt.legend()

plt.plot(x, sin(x), 'r-^', x, sin(2*x), 'b-o')

plt.plot(x,cos(x))

plt.xlabel = ('radians')

plt.ylabel('amplitudo', fontsize='large')

plt.title('Fungsi sin dan cos')

plt.legend(['sin', 'sin', 'cos'])

plt.grid()

plt.show()

Output:

Clearing and closing plots

Clearing and closing plots

from numpy import *

import matplotlib.pyplot as plt

x = linspace(0,2 * pi, 50)

 

#plt.plot(x, sin(x), 'r-^', x, sin(2*x), 'b-o', label = 'sin')

#plt.plot(x,cos(x), label = 'cos')

#plt.legend()

plt.plot(x, sin(x), 'r-^', x, sin(2*x), 'b-o')

plt.plot(x,cos(x))

plt.xlabel = ('radians')

plt.ylabel('amplitudo', fontsize='large')

plt.title('Fungsi sin dan cos')

plt.legend(['sin', 'sin', 'cos'])

plt.grid()

#cls will clear the current plot figure

plt.clf()

#close() will close the currently active plot window

#plt.close()

#plt.close('all')

plt.show()

Output:

Histogram

from numpy import *

import matplotlib.pyplot as plt

plt.hist(random.random_sample(1000), 30)

plt.show()
