[PYTHON/MATPLOTLIB] plot 함수 : 1차 방정식 그리기

■ plot 함수를 사용해 1차 방정식을 그리는 방법을 보여준다.

▶ 예제 코드 (PY)


import matplotlib.pyplot as pp
import numpy as np

xNDArray      = np.arange(0, 10, 0.01)
yNDArray      = 3 * xNDArray + 5
yNoiseNDArray = yNDArray + np.random.randn(len(yNDArray))

pp.figure(figsize = (12, 8))

pp.plot(xNDArray, yNoiseNDArray, label = "noise", color = "y")
pp.plot(xNDArray, yNDArray, ls = "dashed", lw = 3, color = "b", label = "original")

pp.show();
