The answer is a bit complicated, which is unfortunate, but to be fair
the treatment of dashed lines is the greatest single point of difference
between version 4 and version 5.

Let's start with the simple answer.
It has been true all allong (both versions 4 and 5) that you can adjust
the spacing between dashes by using the "dashlength <multiplier>"
option to "set term".
So "set term epslatex dashlength 0.5"  may be all you need.

For the more complicated answer it may be informative to look at
the discussion attached to Bug #1724
    https://sourceforge.net/p/gnuplot/bugs/1724/[1] 

These issues affected only the postscript terminals, but that includes
epslatex.   

- The postscript behavior was tweaked for version 5.0.2
  (released this week).  This tweek may or may not affect what you 
  are doing.

- The original version 4 dashtypes are still there, but the exact 
  commands to select them depend on whether you are in 
  color or monochrome mode.  This will probably work, but I'm 
  not 100% certain:

    set term epslatex
    unset mono
    set for [N=1:10] linetype N lw 1.0 lc black dt N

    ... same plot commands as in version 4 ...

Yes. They work fine here.
