在gnuplot中，图例的字母和行未对齐

问题描述

我是gnuplot的新手.图例的字母和行在gnuplot的输出图中未对齐.

I am new to gnuplot.The letters and lines of the legend are misaligned in my output figure of gnuplot.

我使用了下面的代码.

I used the code below.

gnuplot -persist <<EOF
set size ratio 3/4

set tics font "Arial, 15"

set xrange [494:506]
set yrange [0:1]

set xlabel 'wavelenth [nm]' font "Arial, 20"
set ylabel 'probability' font "Arial, 20" offset -2,0

set lmargin 10
set bmargin 6
set rmargin 25

set key font "Arial, 15" outside  spacing 1.5

plot 'result.out' using 1:2 with lines title "transmittance"
replot 'result.out' using 1:3 with lines title "reflectance" lc rgb "dark-    green"
replot 'result.out' using 1:4 with lines title "absorbance"

set terminal png
set output 'out.png'
replot
EOF

推荐答案

如果您指的是垂直对齐方式，则可以使用set terminal pngcairo而不是set terminal png

If you mean vertical alignment, it can be fixed using set terminal pngcairo instead of set terminal png

可以在图例选项中更改水平对齐方式，例如set key font "Arial, 15" outside spacing 1.5 Left

Horizontal alignment can be changed in legend options, e.g. set key font "Arial, 15" outside spacing 1.5 Left
