我想制作一个带有几十个点的散点图,这些点可能彼此非常接近。我从问题的答案中尝试了注释方法:
>> matplotlib scatter plot with different text at each data point
但是当点彼此足够接近时,您可以看到标签/注释重叠。是否有任何库或方法来生成这样的图,其中各个注释不会相互冲突,也不会与图的边界发生冲突?
import matplotlib.pyplot as plt
z = [0.15, 0.3, 0.45, 0.46, 0.6, 0.75]
y = [2.56422, 3.77284, 3.52623, 3.52623, 3.51468, 3.02199]
n = [58, 651, 393, "393(2)", 203, 123]
fig, ax = plt.subplots()
ax.scatter( z, y )
for i, txt in enumerate( n ):
ax.annotate( txt, ( z[i] + .01, y[i] + .01 ) )
plt.show()
答案 0 :(得分:5)
我已经写了一个库adjustText
来完成这个。 https://github.com/Phlya/adjustText
z = [0.15, 0.3, 0.45, 0.46, 0.6, 0.75]
y = [2.56422, 3.77284, 3.52623, 3.52623, 3.51468, 3.02199]
n = [58, 651, 393, "393(2)", 203, 123]
fig, ax = plt.subplots()
ax.scatter( z, y )
texts = []
for i, txt in enumerate( n ):
texts.append(ax.text(z[i], y[i], txt))
adjust_text(texts)
plt.show()
