我想使用 gnuplot 绘制此数据的条形图。第一列应出现在 x 轴上，第二列和第三列应使用条形图绘制。第二列今天应该有图例，第三列昨天应该有图例。此外，这些值应该出现在每个条形的顶部。

我已经尝试过了

   reset
   dx=5.
   n=2
   total_box_width_relative=0.75
   gap_width_relative=0.1
   d_width=(gap_width_relative+total_box_width_relative)*dx/2.
   reset
   set term png truecolor
   set output "profit.png"
   set xlabel "Year"
   set ylabel "Profit(Million Dollars)"
   set grid
   set boxwidth total_box_width_relative/n relative
   set style fill transparent solid 0.5 noborder
   plot "profit.dat" u 1:2 w boxes lc rgb"green" notitle,\
   "profit.dat" u ($1+d_width):3 w boxes lc rgb"red" notitle

Copied this code from here, works fine for his data file but doesn't work for mine data file pasted at the top

Answer 1

这个怎么样:

set style data histogram 
set style histogram cluster gap 1
set xtics rotate by 90
set style fill solid
plot 'test.dat' using 2:xtic(1) lc rgb "blue", \
     '' using 3
