Re: How to plot multiple fit functions in a single box

Dear Sir,
I corrected that mistake but still I am getting error which is pointing
towards:
% g +  a_1/T

Attached are test.data and test.gnu file (part of test.gnu is mentioned
below).
f(x,a0,a1) = a0 + a1/x
fit f(x,a01,a11) 'test.data' using 1:2 via a01,a11
fit f(x,a02,a12) 'test.data' using 1:3 via a02,a12
fit f(x,a03,a13) 'test.data' using 1:4 via a03,a13
fit f(x,a04,a14) 'test.data' using 1:5 via a04,a14
fit f(x,a05,a15) 'test.data' using 1:6 via a05,a15
fit f(x,a06,a16) 'test.data' using 1:7 via a06,a16
fit f(x,a07,a17) 'test.data' using 1:8 via a07,a17
fit f(x,a08,a18) 'test.data' using 1:9 via a08,a18
plot \
   'test.data' using 1:2 w points pt 1 t  , \
    f(x,a01,a11) t sprintf("K_{fit} = % g +  a_1/T", a01), \
   '' using 1:3 w points pt 1 t  , \
    f(x,a02,a12) t sprintf("K_{fit} = % g +  a_1/T", a02), \
   '' using 1:4 w points pt 1 t  , \
    f(x,a03,a13) t sprintf("K_{fit} = % g +  a_1/T", a03), \
  '' using 1:5 w points pt 1 t  , \
    f(x,a04,a14) t sprintf("K_{fit} = % g +  a_1/T", a04), \
  '' using 1:6 w points pt 1 t  , \
    f(x,a05,a15) t sprintf("K_{fit} = % g +  a_1/T", a05), \
  '' using 1:7 w points pt 1 t  , \
    f(x,a06,a16) t sprintf("K_{fit} = % g +  a_1/T", a06), \
  '' using 1:8 w points pt 1 t  , \
    f(x,a07,a17) t sprintf("K_{fit} = % g +  a_1/T", a07), \
  '' using 1:9 w points pt 1 t  , \
    f(x,a08,a18) t sprintf("K_{fit} = % g +  a_1/T", a08), \
