Re: [Gnuplot-info] Broken histograms when using smooth frequency on data file with discontinuities

[David L. <lin...@ie...>]

I agree that would work. However, my data file happens to also have
several data sets in it (i.e. blocks of data separated by two blank
lines), and I would like to retain that information.

Personally I don't quite understand why plotting with boxes should
yield discontinuities when crossing a gap in the data. Isn't this
kinda lika bug of sorts?
