Please tell us what version of gnuplot you are using and provide
an example of the data.   Since you have not given a "using"
specifier, the data handling depends strongly on what is found
in the first line[s] of the data file.

You might also take a look at the online demos to see if one of
them illustrates the type of plot you are trying to produce.
