這個開始是我繪製的圖表:如何設置軸從角落Matplotlib
# MatPlotlib
import matplotlib.pyplot as plt
# Scientific libraries
import numpy as np
plt.figure(1)
points = np.array([(100, 6.09),
(111, 8.42),
(119, 10.6),
(129, 12.5),
(139, 14.9),
(149, 17.2),
(200, 28.9),
(250, 40.9),
(299, 52.4),
(349, 64.7),
(400, 76.9)])
# get x and y vectors
x = points[:,0]
y = points[:,1]
# calculate polynomial
z = np.polyfit(x, y, 3)
f = np.poly1d(z)
# calculate new x's and y's
x_new = np.linspace(x[0], x[-1], 50)
y_new = f(x_new)
plt.plot(x,y,'bo', x_new, y_new)
plt.show()
我發現,所有的圖形我陰謀沒有從角落開始他們的軸箱子裏,有誰能告訴我如何解決這個問題?除了圖中的設置限制
謝謝,這幫了我一把 – Tian
