Re: [Gnuplot-info] Basic question: how to plot the data on a bar chart?

[<rhu...@ih...>]

Thanks this gets me much closer. 
I don't feel so bad now. That isn't as simple as I had expected.

Now I need to figure out how to add some additional logic to position the label
for those bars that are shorter than the number of chars in the label. I think I
can use a -/+ offset based on the bar size.
 
I tried

gnuplot> help $0

But didn't turn up anything and the mention of $0 in the doc
wasn't enough. Is the $0 in this case relative? 
i.e. is it the position on the x-axis of the x-value from "using"? 

I thought $1 was the first column of the data file so $0 is still unclear to
me.

One thing I found was that the Index in the 4.4 gnuplot.pdf is empty/blank.
Intentional? Or a bug?
