POP-UP DISPLAY QUESTION
Posted by E.D.G. on March 16, 2012

       Several of us are using an older version of Gnuplot (4.2) to work 
with other language computer programs in order to create drawings.  That 
older version is presently being used because the download package only 
needs to contain 2 Gnuplot files.

       I went through the documentation for 4.2 but could not find an answer 
for the following questions.

Question:  Is there a way to get that version to display a pop-up window 
with additional information when the computer mouse is moved to some 
location on the screen?

       We are displaying things such as volcanos on a computer screen map. 
And when the computer mouse is pointing to one of the volcanos on the screen 
we would like to have a pop-up window display additional information such as 
the volcano's latitude and longitude etc.

Question:  If that is not possible with 4.2, is it possible with other 
versions of Gnuplot, and if so, which ones?

Question:  If no version of Gnuplot can do that, can a pipe be opened 
between Gnuplot and say a Perl program running in the background that would 
let Gnuplot send the Perl program the computer mouse X and Y location 
values?
