[Gnuplot-info] data for 2d histogram sorted by x-axis

[Collin M. <cmo...@ya...>]

How do I keep gnuplot from sorting the data by x value? I just want the
bar graph in the order I list it in the input.

And what makes you think that's not what you get?  Please show an actual 
example.

Well taking some data file junk.txt as
42      100
15      90
23      50
11      25
77      10
88      0

And within gnuplot using the command
    plot "junk.txt" w i

I need to see the bars in descending size as the input is sorted, what
I see on my end gnuplot v. 4.0.0, is sorted along the x axis. A
spreadsheet will do what I want without any extra manipulation but I
just wanted to automate the process with gnuplot instead.

That's not "sorting" along the x axis, that's positioning the impulses
where your x axis data say they should be.  That's what x axis data are
*for*.  If you don't want that, drop those x data, i.e. either don't put 
them into the file, or tell gnuplot to ignore them:

	plot "junk.txt" u 2 w i
