Is this what you are looking for:

set polar
set angles degrees
set size square
set xrange[-2:2]
set yrange[-2:2]
plot "data.dat"

where data.dat is:

0       1
15      1
30      1
45      2
60      1
75      1
90      1
105     1.5
120     1
135     1
150     1
165     1
180     1.7
195     1
210     1
225     1
240     1
255     1
270     1.2
285     1
300     1
315     1
330     1.8
345     1
