我試圖用GNUPLOT製作這個直方圖,但我無法理解如何顯示國家的名稱(我也放了我的dati.dat文件)。在直方圖中改變Y軸的距離GNUPLOT
下面的代碼:
reset
set terminal pngcairo size 500,500 enhanced font 'Verdana,10'
set output 'Err_rev.png'
# this command to modify the orientation of the png
#convert -rotate 90 Err_rev.png Err_rev_out.png
set key at graph 0.24, 0.80 horizontal samplen 0.1
set style data histogram
set style histogram cluster gap 2
set style fill solid border -1
set boxwidth 0.8
set xtic rotate by 90 scale 0
unset ytics
set y2tics rotate by 90
set yrange [0:100]; set xrange [*:*]
set y2label 'Paragone tra Nazioni: Domicilio - Hospice ' offset -2.5
set xlabel ' '
set size 1, 0.96
set label 1 'Nazioni' at graph 0.5, -0.1 centre rotate by 180
set label 2 'Domicilio' at graph 0.135, 0.83 left rotate by 90
set label 3 'Hospice' at graph 0.21, 0.83 left rotate by 90
p 'dati.dat' u 2 title ' ', '' u ($2/2.0+rand(0)/10.0) title ' ', '' u 0:(0):xticlabel(1) w l title ''
而這裏FILE.DAT:
Inghilterra 63 29
Belgio 71.6 9.9
Germania 66 14.8
Olanda 83.1 10.5
Portogallo 50.1 35.7
Spagna 60.1 16.8
Italia 76.1 12
非常感謝。
