我正在使用以下代码绘制直方图
set style data histogram
#clustered
#set terminal wxt enhanced persist
set term post eps enhanced "Times-Roman, 14"
set output 'tostack.eps' #change here
#set boxwidth 0.9
set grid
set auto y
#set auto x
set auto y
#set ylabel format "{/:Bold}"
#set size 1.35,0.35
#set title ""
set style histogram clustered gap 1 title offset 1,0.25
set ylabel "\nXXX (in %)\n\n" font "Times-Roman ,25" #change here
set xlabel "\nYYY \n" font "Times-Roman,25" #change here
#set style fill solid noborder
set style fill pattern border -1
set key right
set key spacing 3 font "Times-Roman,20"
set xtics font ", 20"
set ytics font ", 20"
plot for [COL=2:5] 'tostack.dat' using COL:xticlabels(1) title columnheader fs pattern 2
我的数据文件是
AA BB CC DD EE
100 23.6491500555 6.9743235667 6.5497090218 6.9819639165

在生成的直方图中,我怎样才能只为每组中值较大的条插入标签。
也请帮我把这些标签加粗。
