也許使用plt.annotate:
import numpy as np
import matplotlib.pyplot as plt
N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]
plt.subplots_adjust(bottom = 0.1)
plt.scatter(
data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
cmap=plt.get_cmap('Spectral'))
for label, x, y in zip(labels, data[:, 0], data[:, 1]):
plt.annotate(
label,
xy=(x, y), xytext=(-20, 20),
textcoords='offset points', ha='right', va='bottom',
bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))
plt.show()
這就是我要說的。鏈接到文檔:http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.annotate鏈接到演示:http://matplotlib.sourceforge.net/examples/pylab_examples/annotation_demo2.html – Paul 2011-02-28 21:06:38
非常好!它像一個魅力。 – 2011-02-28 21:12:49
@ubuntu是否有可能使用數字(或標籤)_index of the points? – Vladtn 2012-02-29 13:40:31
