#2340 — exit from the reread loop

Hello,

the command reread is very useful, but if the gnuplot file is launched, 
for example, through a desktop shortcut, then untrained user may not 
understand how to completely close gnuplot window (ctrl+alt+del in 
Windows, "killall gnuplot" in Linux). Is there a way to close gnuplot 
window and exit from the endless loop?

Not clear what you mean. Can you show a small example script?

you know

  if (<rereadcondition>) reread

, i guess? Also "pause -1" gives the uses an opportunity to stop a script.

We measure a long-term process. It's unknown when it will end. Here is a 
script:

set term wxt enh font ",12"
set format y "%.2tE%+02T"
unset key
set grid xtics
set grid ytics

plot "/home/michael/tmp/data.dat" u 2:5 w lines lw 2
pause 5
reread

You could check for differences between the last two plots. Say the x
axis in your plot gets ever longer:

====

if (!exists("nowmaxx")) nowmaxx = 0 # initialize the variable

lastmaxx = nowmaxx
nowmaxx = GPVAL_DATA_X_MAX

plot ...

if (lastmaxx <> nowmaxx) reread

====

there are other GPVAL_ status variables that are updated after every
plot. Or you could use "stats" on your datafile, and use one of the
stats status variables.

Oh, thanks! I just wasn't sure what condition should I use for exiting.

Does anyone else see five cyrillic letters (transliterating to "wrote")
after my name above?

It's quite a late reply, but I hope could be useful for other users.
Usually I escape from 'reread' loop using a variable and a binding.

bind "Close" "reread_loop = 0" 
reread_loop = 1
if(reread_loop==1) reread

I'm using gnuplot5.0.
That's my 2 cents.

Dario
