在 gnuplot 中绘制多列

Question

我认为您的第一个图不是根据您提供的数据绘制的。在该图上，点在垂直轴上大约位于 50 到 80 之间。在数据文件中，没有一个点在该范围内。

不过，也许这个脚本可以帮助您入门。

# Horizontal grid lines only.
set grid y linetype 1 linecolor 0 linewidth -0.5

# Plots with lines instead of points.
set style data lines

# Legend below the plot.
set key outside bottom center horizontal

# Extend the range of the axis a little so the data points don't end up
# on the edge of the plot.
set offsets graph 0.1, graph 0.1, graph 0.1, graph 0.1

# Remove the border around the plot.
unset border

# No tick marks on the right and top.
set xtics nomirror
set ytics nomirror

set title 'Chart Title'

# Make the lines thicker by setting lw (short for linewidth) larger than 1.
plot 'data.txt' using 1 lw 3 title 'Potenciální',\
     'data.txt' using 2 lw 3 title 'Kinetická',\
     'data.txt' using 3 lw 3 title 'Celková'
