I'd like to do a bar chart using gnuplot.
I used this settings
set style data boxes
set style fill solid
plot 'foo.dat' using 1:2:(1) linewidth 2
with the content of foo.dat being
8 1
10 1
11 4
12 4
gnuplot only displays the bars corresponding to the last two lines.
Why ? Is there an other solution than adding "9 0" into my data file ?
Thank you in advance
Your y-axis is probably autoscaled to [1:4]. Use e.g.
set yrange [0:*]
Then the axis always starts at 0 but is autoscaled at the other end.
