Error plotting labels gnuplot

Question

I would like to plot this datafile

"/root/temp.txt"

LB|30|421
CN|50|247
BR|20|370
SA|12|310

Where the first column is the X Axis, the second one is the Y Axis and the third one the label to put above each column of the histogram.

Before now, I use this syntax to plot the graph (but without any label)

set terminal png ;
set title "Hello" ;
set xlabel "Country" ;
set ylabel "values" ;
set style fill solid ;
set xtic rotate -45 ;
set datafile separator "|" ;
set style data histograms ; 
plot '/root/temp.txt' using 2:xtic(1) notitle

But if I try to add labels gnu plot give me error!!

The syntax I use to add labels is plot '/root/temp.txt' using 2:xtic(1):3 with labels notitle

Could you please help me? Thank you

Could you also post how you are trying to add the labels? Then it is easier to see what is going wrong. — Woltan

I am not sure that you can compress into one plotting format, but you can use replot (or replot-like plot):

plot '/root/temp.txt' using 2:xtic(1) notitle, '' u ($0):2:3 with labels notitle

Empty '' induce reuse the last input(file). Now, it equals with '/root/temp.txt'

To be nicer:

plot 'temp.txt' using 2:xtic(1) notitle, '' u ($0+0.1):($2+1):3 with labels notitle

Oh! And don't forget to set output of png term!
