Quickest way of plotting scientific histograms

[motoroller]

I've tried a few methods of plotting histograms from unsorted data, but they're all extremely involved (ROOT) or look very "childish" (online tools).

What's the easiest way of plotting a histogram from a unicode text file with numbers in it?

Thanks in advance - need the histograms for some project work.

For easy and (if you bother to learn the style-altering commands) professional looking plots of not-too-complicated data I recommend gnuplot.

You might be able to import the file into Open Office or Excel in the same way that a .CSV file can be imported. I know there are different options in Open Office for setting delimiters.
