[Paraview] Data range problem

[Lester Anderson]

I have used a plain text editor to write a simple ascii structure, and also tried using Surfer (Golden Sofware) to prepare .DAT file do the same (eg space delimited or comma delimited). Basically I am testing a simple ascii text file structure and it ckearly loads the data (points plot where they should be), but it is unclear how to set the data type. If we are dealing with positive an negative numbers then I assume that means we need a signed integer or real number type.
 
Perhaps if you could show an example data file that works in the raw import as an xyz,value it might be clearer as to how to proceed. Thanks for the help, I'm sure I'm missing something very obvious here just can't put my finger on it yet!
