#1442 — this should not be so difficult ?

   To reduce my problem down to something very simple, I have created the input file (called 'in' below):

set term x11 persist
set view 0,0
set pm3d
set palette
splot x**2+y**2

If I go into gnuplot and type 

load 'in'

everything works just fine.   If, on the other hand, I execute

gnuplot < in

everything works EXCEPT that the association of mouse position with plot coordinates is lost.    It simply displays x=0 and y=0 in the lower-left corner and has no response at all when I move the mouse.   However, if I change this to a one dimensional plot

set term x11 persist
plot x**2

then the mousing business works either way I invoke the file.    

Help!!!!   I am running gnuplot 4.6.0 on a MBP...

What task are you trying to accomplish?

   Simply to put a plot up on my screen (necessary to read in the data from a file) and then move the cursor around and pick off the coordinates.

Simplest answer:
 
  Add a line at the end of your script file "pause mouse key"
  Now invoke it like this:

     gnuplot infile &

  Mousing will continue to work, including middle-click to print coordinats
  on the plot, until you hit some keyboard key while the plot window has focus.

More information:

  There are two things contributing to your problem.
  
  One is that you would do better to use "set view map" 
  rather than "set view 0,0".
  
  However there is apparently an x11 terminal specific bug that
  prevents your test case from working even with set view map.
  The development version of gnuplot contains a fix, 
  but that doesn't help you right now.

   Thank you.   That works beautifully.
