[Gnuplot-info] Non-numeric x-axis data

[Venkateswaran, B. <Bha...@ny...>]

Hi,

I am just beginning to use gnuplot. I went through some documentation to try
and plot the dataset represented below but am doing something wrong. My data
looks like this:

#Name  Value
AAA      -1.1323
BBB       0.7345
CCC      -57.273
DDD      4.6752

I want to plot a bar graph and this is the snippet I tried:
set xtics ("AAA" 1, "BBB" 2, "CCC" 3, "DDD" 4)
set xrange [0:5]
set format y "%f"
set yrange [-60:5]
plot 'values.dat' using 1:2 with boxes

I would appreciate if someone could tell me what it is that I am missing.
Thanks.
