Sounds to me like you have
"too many columns in using specification"
One obviously path to solving this could be to look closely at the number of columns in your data and the number of columns in your gnuplot command (specification).
I am using 6 columns:
x : y : min x : max x : min y: max y
where min and max are the range of the errors for x and y... when I plot a file withe these columns I get a correct plot, but I can't use the same thing to fit the data... do you know what I mean?

My input data has occasional holes in it, spots where a sensor couldn't be read. These are ERR in the data file instead of a floating point number. What should I change them to, for gnuplot to ignore these values instead of whining about them? (1 Reply)
