无法使3D文本注释散点图。
尝试了Axes3D.text,plt.text,但不断出现“缺少必需的位置参数s”的情况。您如何在3D中循环注释?
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
from matplotlib.patches import Ellipse
import pandas as pd
import numpy as np
df = pd.read_csv (r'J:\Temp\Michael\Python\9785.csv')
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
#Scatter plot
for i in df.index:
x = df.at[i,'x']
y = df.at[i,'y']
z = df.at[i,'h']
ax.scatter(xs=x, ys=y, zs=z, s=20,color='red',marker='^')
label = df.at[i,'to']
Axes3D.text(x+0.8,y+0.8,z+0.8, label, zdir=x)
TypeError:text()缺少1个必需的位置参数:'s'
答案 0 :(得分:0)
更改:ax = fig.add_subplot(111,projection ='3d')
至:ax = fig.gca(projection ='3d')
解决了问题。用过的ax.text。

fig = plt.figure()
ax = fig.gca(projection='3d')
#Scatter plot
for i in df.index:
df.set_index('to')
x = df.at[i,'x']
y = df.at[i,'y']
z = df.at[i,'h']
ax.scatter(xs=x, ys=y, zs=z, s=20,color='red',marker='^')
ax.text(x+0.8,y+0.8,z+0.8, df.at[i,'to'], size=10, zorder=1)
