我是 matplotlib 的新手。我在 matplotlib 中的图表没有完全显示最后一个标记。我尝试增加图形大小,但没有任何变化。我需要扩展图形,使其显示最后一个标记,并将线延伸到标记之外。这是我的代码:
import numpy as np
import matplotlib.pyplot as plt
x = np.array([1,2,5,10,15,20])
y = np.array([0.049,0.080,0.123,0.166,0.209,0.335])
A = np.vstack([x, np.ones(len(x))]).T
m, c = np.linalg.lstsq(A, y)[0]
x = np.array([0,1,2,5,10,15,20])
y = np.array([c,0.049,0.080,0.123,0.166,0.209,0.335])
plt.plot(x, y, 'r*', label='Original data', markersize=7)
plt.plot(x, m*x + c, 'b', label='Fitted line')
fig = plt.figure(1)
fig.set_size_inches(9,8)
fig.suptitle('THE GRAPH OF ABSORBANCE AGAINST CONCENTRATION',fontsize=20)
plt.xlabel('CONCENTRATION',fontsize=15)
plt.ylabel('ABSORBANCE',fontsize=15)
plt.grid()
fig.savefig('graph.jpg')
非常感谢您的帮助。
