gnuplot x label position in histogram

Question

i have the following data:

t_4 24 3 0 0
t_6 37 4 0 0
t_8 51 4 2 0 

t_4 15 1 0 0
t_6 21 0 0 1
t_8 30 0 0 1

t_4 13 2 1 0
t_6 20 3 1 0
t_8 22 4 1 0

and i try to make an histogram similar to this http://www.bmsc.washington.edu/people/merritt/gnuplot/stack+cluster.dem , with this modify version of the code:

set style data histogram
set style histogram rowstacked
set style fill solid
set boxwidth 0.5
set key invert samplen 0.2
set key samplen 0.2
set bmargin 3
set offset 0,2,0,0

set title "number of multiple resonances"

plot newhistogram "1:j" lt 1, \
     'stack+cluster.dat' index 0 u 2:xtic(1) title "one", \
     '' index 0 u 3 title "two", \
     '' index 0 u 4 title "three", \
     '' index 0 u 5 title "four"

     newhistogram "2:j" lt 1, \
     'stack+cluster.dat' index 1 u 2:xtic(1) notitle, \
     '' index 1 u 3 notitle, \
     '' index 1 u 4 notitle, \
     '' index 1 u 5 notitle

      newhistogram "3:j" lt 1, \
     'stack+cluster.dat' index 1 u 2:xtic(1) notitle, \
     '' index 1 u 3 notitle, \
     '' index 1 u 4 notitle, \
     '' index 1 u 5 notitle

but this is the output i found

As you can see the problem is in the x labels names newhistogram "1:j" , "2:j" and "3:j" : i can see only "1:j" and overlapped with the "t_4...".

Can someone help me, please?

Answer 1

That script gives an error! All commands must belong to a single plot commands. As you have it, the script terminates before the second newhistogram.

The next thing is, that you need to separate two blocks with two blank lines in order to address them with the index parameter (for this see also the comments in the data file http://www.bmsc.washington.edu/people/merritt/gnuplot/stack+cluster.dat which belongs to the example you talked about).

With these corrections you get the following script (note also the title offset):

set style data histogram
set style histogram rowstacked title offset 0,-1
set style fill solid
set boxwidth 0.5
set key invert samplen 0.2
set key samplen 0.2
set bmargin 3
set offset 0,2,0,0

set title "number of multiple resonances"

plot newhistogram "1:j" lt 1, \
     'stack+cluster.dat' index 0 u 2:xtic(1) title "one", \
     '' index 0 u 3 title "two", \
     '' index 0 u 4 title "three", \
     '' index 0 u 5 title "four",\
     newhistogram "2:j" lt 1, \
     'stack+cluster.dat' index 1 u 2:xtic(1) notitle, \
     '' index 1 u 3 notitle, \
     '' index 1 u 4 notitle, \
     '' index 1 u 5 notitle,\
      newhistogram "3:j" lt 1, \
     'stack+cluster.dat' index 1 u 2:xtic(1) notitle, \
     '' index 2 u 3 notitle, \
     '' index 2 u 4 notitle, \
     '' index 2 u 5 notitle

with the result (with 4.6.5):
