title: 3d scatter plot wiht 3-dimension list
body: <pre><code>print(grid)
  
  xmin, xmax, ymin, ymax, zmin, zmax = 0, x, 0, y, 0, z  
  plt.rcParams[&quot;figure.figsize&quot;] = (6, 6)  
  fig = plt.figure()  
  ax = fig.add_subplot(111, projection='3d')
  
  plt.plot(grid)
  plt.grid(True)
  plt.show()
  
  ax.scatter(x,y,z)
  </code></pre>
  <p>I want to plot 3D scatter graph. but scatter() always has to use x,y,z data frame. There is only a 3-dimension list data that I have. I want 3d scatter plot with 3-dimension list as picture below.</p>
