Dear all,

Hi. I have a multiple GNSS data measured from RTK in the field.  
Examples.  
344386.419 ,397251.039 , 142.620  
344357.387 ,397240.493 , 142.630  
344356.652 ,397242.586 , 142.600  
344385.795 ,397252.367 , 142.650  
344376.108 ,397264.315 , 142.660  
344351.690 ,397255.796 , 142.530  
344351.075 ,397257.170 , 142.590  
344375.472 ,397265.606 , 142.650  
344361.605 ,397247.018 , 142.610

First column means Longitude, Second Latitude, and Third Elevation.  
This data is in the file type, csv with “,” delimiters.

I hope to plot those in the paraviewa.  
First of all, I tried to use TabletoPoints, but I got this error below.

```auto
ERROR: In /build/paraview-vlxewD/paraview-5.7.0/VTK/Filters/General/vtkTableToPolyData.cxx, line 110

```

Could you give me some suggestion to show GNSS data in the paraview?

Thank you very much.
