[Gnuplot-info] bar chart; bars are on top of each other

[Tilly <new...@go...>]

Hello everyone!

I wanted to create a bar graph from three different dat. files. For the
x-value in 1918, the numbers of all files are displayed as a bar. The
structure of the data looks like this:

# num-nat.dat
1918       1542
1919       1478
...

# num-mem.dat
1918       13542
1919       14478
...

# num-small.dat
1918       17421
1919       16278
...

In the plot the bars are on top of each other and are covered by the
largest ones.

<Code>
set yrange [0:21000]
set xrange [1917.5:1929.5]
set xtics 1

set style data histogram
set style histogram clustered
set style fill solid border lt -1
#unset style fill
set boxwidth 0.25
set bars 1

plot "anzahl-nat.dat" title "FED" with boxes, "anzahl-mem.dat" title
"Member"  with boxes, "anzahl-small.dat" title "Small" with boxes
</Code>

Can someone please give an example of the right plot command?

Thanks,
Tilly
