   ### One-line summary 
   I am attempting to draw a flat vertical 3D Surface square with 4 data points, all with a constant X and
   I can not get anything to render if all of the X axis are the same.
   
   data:[
           [5, 0.01, 10.323],
           [5, 0.01, 10.802],
           [5, 0.2, 10.323],
           [5, 0.2, 10.802]
         ]
   
   If the 2nd and 4th data point contain a larger X axis however, the 3D surface I am attempting to plot renders perfectly.
    
   data:[
           [5, 0.01, 10.323],
           [5.00000001, 0.01, 10.802],
           [5, 0.2, 10.323],
           [5.00000001, 0.2, 10.802]
         ]
   
   How can I get this flat vertical 3D surface to display with a constant X axis?
