▶ 예제 코드 (PY)


import matplotlib.pyplot as pp
import numpy as np

pointCount = 1000
xList = []
yList = []

for i in range(pointCount):
    x = np.random.normal(0.0, 0.55)
    y = x * 0.1 + 0.3 + np.random.normal(0.0, 0.03)
    xList.append(x)
    yList.append(y)

pp.plot(xList, yList, "ro")

figure = pp.gcf()

pp.grid()
pp.show()

figure.savefig("result.png")
