this can not work, because in gnuplot the contents of one record in the
file are separated by whitespace (=one or more blanks or tabs)
this means starting from the 3rd record your data file contains
only 5 values per record:
<pre>
0.046	4.74	0.0901	0.45	0	0.01	0.01
0.086	4.74	0.0762	0	0.225	0.05	0.001
0.129	4.74	0.0586			0.002	0.001
0.146	4.74	0.0511			0.05	0.001
</pre>

set datafile missing "?"
and produce a new data file with this missing character
at the place of a missing values:
<pre>
0.046	4.74	0.0901	0.45	0	0.01	0.01
0.086	4.74	0.0762	0	0.225	0.05	0.001
0.129	4.74	0.0586	?	?	0.002	0.001
0.146	4.74	0.0511	?	?	0.05	0.001
</pre>

or,
set datafile separator "\t"
this should work because the values in your file are separated by
tab characters.
