gnuplot使用epslatex绘图，只显示坐标轴等信息而没有曲线，如图： 数据来源如下：http://www.gnuplotting.org/label-size-in-epslatex-terminal/ gnuplot代码如下： set terminal epslatex size 9cm,7cm color colortext standalone header \ "\\newcommand{\\ft}[0]{\\footnotesize}" set output 'photo_luminescense2.tex' set border linewidth 1.5 set style line 1 lc rgb '#800000' lt 1 lw 2 set style line 2 lc rgb '#ff0000' lt 1 lw 2 set style line 3 lc rgb '#ff4500' lt 1 lw 2 set style line 4 lc rgb '#ffa500' lt 1 lw 2 set style line 5 lc rgb '#006400' lt 1 lw 2 set style line 6 lc rgb '#0000ff' lt 1 lw 2 set style line 7 lc rgb '#9400d3' lt 1 lw 2 unset key set style line 11 lc rgb '#808080' lt 1 set border 3 back ls 11 set tics nomirror out scale 0.75 set style line 12 lc rgb'#808080' lt 0 lw 1 set grid back ls 12 set mxtics 2 set mytics 10 set xrange [0.6:1.9] set xtics 0.1,0.2,1.9 set xlabel 'Photon energy / eV' set ylabel 'Phot. flux density / m$^{-2}$s$^{-1}$eV$^{-1}$sr$^{-1}$' offset 1,-0.5 set logscale y set yrange [1e7:1e22] set format '$%g$' set format y '$10^{%T}$' set datafile separator "," set label 2 '\ft $5$\,meV' at 1.38,4e9 rotate by 78.5 center tc ls 1 set label 3 '\ft $10$\,meV' at 1.24,2e10 rotate by 71.8 center tc ls 2 set label 4 '\ft $20$\,meV' at 1.01,9e11 rotate by 58.0 center tc ls 3 set label 5 '\ft $40$\,meV' at 0.81,1e15 rotate by 43.0 center tc ls 4 set label 6 '\ft $60$\,meV' at 0.76,9e16 rotate by 33.0 center tc ls 5 set label 7 '\ft $80$\,meV' at 0.74,2.5e18 rotate by 22.0 center tc ls 6 set label 8 '\ft $E_0 = 100$\,meV' at 1.46,5e18 rotate by -40.5 center tc ls 7 plot 'PL_spectrum_mu_1.0eV_E0_05meV_300K.dat' u 1:2 w l ls 1, \ 'PL_spectrum_mu_1.0eV_E0_10meV_300K.dat' u 1:2 w l ls 2, \ 'PL_spectrum_mu_1.0eV_E0_20meV_300K.dat' u 1:2 w l ls 3, \ 'PL_spectrum_mu_1.0eV_E0_40meV_300K.dat' u 1:2 w l ls 4, \ 'PL_spectrum_mu_1.0eV_E0_60meV_300K.dat' u 1:2 w l ls 5, \ 'PL_spectrum_mu_1.0eV_E0_80meV_300K.dat' u 1:2 w l ls 6, \ 'PL_spectrum_mu_1.0eV_E0_100meV_300K.dat' u 1:2 w l ls 7 Tex文件代码如下： % GNUPLOT: LaTeX picture with Postscript \documentclass{minimal} % Set font size \makeatletter \def\@ptsize{1} \InputIfFileExists{size11.clo}{}{% \GenericError{(gnuplot) \space\space\space\@spaces}{% }{See the gnuplot documentation for explanation.% }{For using a font size a file \def\@ptsize{0} \input{size10.clo}% }% \makeatother % Load packages \usepackage{calc} \usepackage{graphicx} \usepackage{color} \makeatletter % Select an appropriate default driver (from TeXLive graphics.cfg) \begingroup \chardef\x=0 % % check pdfTeX \@ifundefined{pdfoutput}{}{% \ifcase\pdfoutput \else \chardef\x=1 % \fi }% % check VTeX \@ifundefined{OpMode}{}{% \chardef\x=2 % }% \expandafter\endgroup \ifcase\x
