RE: .csv file

Hi Bill,

The visad spreadsheet was able to load in my csv file that had 7 input fields 
when I modified the header to what you suggested. However, I am trying to 
produce a 3-D glyph plot in which 3 fields are mapped to 3 parameters such as 
the x, y, and z axis, and 3 other fields mapped to 3 additional parameters 
local to that (x, y, z) point.

However, when I load in my file with 7 input fields and create the mappings 
for a glyph plot, I only see about 3 small points on different faces of the 
cube rather than many points scattered throughout. Do you think the scarce 
number of plots could be from the values I gave each input field in my .csv 
file (some possibly too small) or could it be from the function I set up in 
the header?: 
(index) -> (GPA, Distance, Phone, Shoesize, Year, Xoffice, Yoffice, 
Firstname(Text), Lastname(Text)).

I'm not exactly sure why these input fields like GPA and distance should be 
dependent variables and if they are going to be dependent variables, are you 
arbitrarily assigning the index to it?
