I am quite familiar with the 3D graph utilities in LabVIEW, but I recently discovered some strange behavior of the grid lines that I don't understand. See attachment. There are vertical gap/distortion features in the grid that appear to be errors in the generation of grid triangles. My first thought was that there was a problem with the input data. However, by simply adjusting the scaling of the X and Y axes, these grid features can be made to appear and dissappear, move around to different locations on the grid, and even the number of them changes. I don't think these effects can be explained by bad data. Does anyone out there have any ideas about what might be causing these features?
