如何通过pyplot从3Dplot导出标记点数据点？
这是我的源代码：
from mpl_toolkits.mplot3d import Axes3D as ax
import numpy as np
import matplotlib.pyplot as plt
import math
def read(n):
from xlrd import open_workbook
book = open_workbook(n)
sheet = book.sheet_by_index(0) #If your data is on sheet 1
column1 = []
column2 = []
column3 = []
for row in range(0,601): #start from 1, to leave out row 0
column1.append(sheet.cell_value(row,0))#extract from first col
column2.append(sheet.cell_value(row,1))
column3.append(sheet.cell_value(row,2))
xdata = []
ydata = []
zdata = []
xdata=column1.copy()
ydata=column2.copy()
zdata=column3.copy()
return xdata,ydata,zdata
n='test.xlsx'
xdata=np.array(read(n)[0])
ydata=np.array(read(n)[1])
zdata=np.array(read(n)[2])
fig = plt.figure()
ax = plt.axes(projection='3d')
ax.plot3D(xdata, ydata, zdata,marker='o',color='green',markevery=0.05)
#ax.scatter3D(xdata, ydata, zdata,marker='o',color='green',markevery=0.05)
for x, y in zip(xdata, yList):
plt.text(x, y+0.3, str(y), ha='center', va='bottom', fontsize=10.5)
plt.grid()
plt.show()
我只能绘制点，但不能将其导出。
我需要一个标记点来创建新路径。
感谢您的帮助！
