#2796 replot of multiplot fails with "unexpected or unrecognized token:"

[Daniel Dan K.]

Hello,

I regularly use replot in my scripts, e.g., for creating an image of the plot or for replotting periodically updated data.

replot also works with multiplots.
However, replot fails with multiplots when the command is followed by another command. Let me explain by examples.

This code works:

plot sin(x)*rand(0)
while (1) { replot ; pause 1 ; }

This code fails:

set multiplot layout 2,1
plot sin(x)*rand(0)
plot cos(x)*rand(0)
unset multiplot
while (1) { replot ; pause 1 ; }

with

gnuplot> replot ; pause 1 ;
                  ^
         unexpected or unrecognized token: pause

Why is this? What can I do about it?
Thanks.
Daniel

It's a bug.
The fix is probably simple but for now...

Work-around:
Put an extra semicolon after the replot command.
while (1) { replot ;; pause 1 }

Thanks, Ethan, for providing a workaround so quickly. That's helpful.
