label, awk/grep, histogram
bryan
grep within gnuplot to calculate the position of the label from the
data itself e.g. move it up by 0.1 from the data point. my gnuplot
script and data are below - tried to keep it simple. as is, the
labels show up on 0,0 (i think) instead of above the top of the bar.
the grep/awk bit seems to work as tested with !, but still i can't see
why this is not working. i tried printf also, that did NOT work.
there are no error messages.

Use the 'labels' style (help labels). For example, amend your plot
command with
for [i=1:4] '' u 1:($2+0.1):("Label ".i) every ::i w labels

nice! i did this :
for [i=0:3] '' u 1:($2+0.1):5:xticlabel(5) every ::i w labels notitle
lw 2 lc -1
... it doesn't look like the labels can be rotated that way - is that
right?

They can be rotated alright! Use the 'rotate' keyword, just as you
would with "set label".
The order of keywords is not completely free, certain combinations may
give an error message.
Look up the syntax of "set label", the order described there is
guaranteed to work.
By the way, 'lw 2 lc -1' does not do what you think it does. 'lw 2' is
meaningless, use 'font ",fontsize"', where fontsize is a number, if
you want to control font size. And write 'tc lt -1' instead of 'lc -1'
- perhaps their full form 'textcolor' instead of 'linecolor' is more
intuitive.
So, putting it together:
plot for [i=0:3] '' u 1:($2+0.1):5:xticlabel(5) every ::i w labels
rotate by 90 tc lt -1 notitle
A tip to set font sizes: declare a variable, like 'fs = 10'. Use that
when you set up your terminal:
set term whatever font "fontname,".fs
Then use
font ",".(fs*2)
in your plot command to get labels that are twice as big as the tick
markings, axis labels etc. This way, if you change your terminal, or
your plot size, you can just set fs to the desired value, and the
labels created by 'plot' will scale accordingly.

this would be brillant except that all the xticlabels are lost (see
new data file) - is this an impossible 'conflict'?:
for [i=0:1] 'data_1.dat' u 1:2:3:xticlabel(4) every ::i w boxerror
notitle lw 2 lc 1,
for [i=2:2] '' u 1:2 every ::i notitle lc -1 ps 0 lw 0,
for [i=3:4] '' u 1:2:3:xticlabel(4) every ::i w boxerror notitle lw 2
lc 2,
for [i=0:4] '' u 1:($2+0.1):5:xticlabel(5) every ::i w labels notitle
lw 2 tc lt -1 rotate by 90
new data file :
