Question

在执行PyQt程序时，更新的图形将绘制在第一个图形上。我希望该图形显示在QWidget中显示的Window中。以下想法适用于3D线以及点图，但不适用于用于表面图。

MockHttpServletRequest:
         HTTP Method = POST
         Request URI = /myapibase/v1/clients
          Parameters = {}
             Headers = {Content-Type=[application/json]}

             Handler:
                Type = null

               Async:
       Async started = false
        Async result = null

  Resolved Exception:
                Type = null

        ModelAndView:
           View name = null
                View = null
               Model = null

            FlashMap:

MockHttpServletResponse:
              Status = 404
       Error message = null
             Headers = {}
        Content type = null
                Body = 
       Forwarded URL = null
      Redirected URL = null
             Cookies = []

您只需要在绘制之前清除轴：

import os, zipfile
import shutil
import os
from os import path


dir_name = 'C:\\Users\\Guest\\Desktop\\OJT\\samples'
destination = 'C:\\Users\\Guest\\Desktop\\OJT\\scanner\\test'
for path, subdirs, files in os.walk(destination):
    for name in files:
        filename = os.path.join(path, name)
        shutil.copy2(filename, destination)

我还添加了一些随机数以使更新可见。这是完整的代码：

def DrawGraph(self, x, y, z):#Fun for Graph plotting
    self.axes.clear() # <<<
    self.axes.plot_surface(x, y, z) #plots the 3D surface plot
