cygwin startxwin.bat does not work - cygwin

Question

I tried to install x11 for cygwin. The installation appears to go well BUT there is no startxwin.bat file as described in the docs. I downloaded this file manually and put it in the right place. It runs and in taskmanager I see xwin.exe - BUT there is no "TERMINAL".
Can anyone help?
PS: I am trying to get x11 because I believe I need it to plot prettily in gnuplot - could some confirm that I do need x11 for that.
OUTPUT from calling startxwin in CYGWIN-terminal:
$ startxwin

Answer 1

startxwin.bat has been removed in favor of startxwin.exe... http://permalink.gmane.org/gmane.os.cygwin.xfree/20615
Look for it in /bin

Answer 2

I don't think that you need X11 for gnuplot on Windows. See: http://www.gnuplot.info/ :
Gnuplot supports many different types of output
interactive screen display: cross-platform (Qt, wxWidgets, x11) or system-specific (MS Windows, OS/2)
static screen display: system-specific (OSX(aqua), svga, ...)
direct output to file: postscript (including eps), pdf, png, gif, jpeg, LaTeX, metafont, emf, svg, ...
mouseable web display formats: HTML5, svg
However, it might be easier to use a different precompiled binary. See: http://www.maths.manchester.ac.uk/~pjohnson/Gnuplot/windows_gnuplot.html
