[Gnuplot-info] Newhistogram: zero data columns and key height

[Giacomo M <jac...@gm...>]

Dear all,
I am using newhistogram and I am experiencing the following unwanted
behaviours:
1) thin colored lines appear on top of the bars (as if also "0-level" data
was represented)
2) key is taller than it should be (as if each newhistogram included their
own key entries even though I specified them only for the first one)

In particular, I used the commands:
set style data histogram
set style histogram rowstacked gap 1
set style fill pattern
plot newhistogram "N", "data.txt" i "N" u 2:xtic(1) t "wind" fill p 1 lc
rgb "#094f7e", "" i "N" u 3:xtic(1) t "photo", "" i "N" u 4:xtic(1) t
"coal" fill p 4 lc rgb "#ac0f0c", "" i "N" u 5:xtic(1) t "ccgt" fill p 5 lc
rgb "#91a00b", "" i "N" u 6:xtic(1) t "otherfuel",\
newhistogram "CN", "data.txt" i "CN" u 2:xtic(1) notitle fill p 1 lc rgb
"#094f7e", "" i "CN" u 3:xtic(1) notitle, "" i "CN" u 4:xtic(1) notitle
fill p 4 lc rgb "#ac0f0c", "" i "CN" u 5:xtic(1) notitle fill p 5 lc rgb
"#91a00b", "" i "CN" u 6:xtic(1) notitle,\
newhistogram "CS", "data.txt" i "CS" u 2:xtic(1) notitle fill p 1 lc rgb
"#094f7e", "" i "CS" u 3:xtic(1) notitle, "" i "CS" u 4:xtic(1) notitle
fill p 4 lc rgb "#ac0f0c", "" i "CS" u 5:xtic(1) notitle fill p 5 lc rgb
"#91a00b", "" i "CS" u 6:xtic(1) notitle,\

and I obtained this:

I'm using gnuplot 4.5 patchlevel 0 (last modified 2011-10-14, system
MS-Windows 32 bit)

Any help is more than appreciated,
thanks,

PS: any suggestions on how to clean up the plot command is also very
welcome, thanks!
