Gnuplot：在按键时跳出循环

Question

在 GnuPlot 5.2 脚本中是否可以在按下（特定）键时跳出循环？

do for [m=1:6] {      
  do for [i=1:3] {
     do for [fr=0:25] {
        splot 'ex.plt' using 2:3:4 w l lt 1, sprintf("'exm%d.%d'",m,fr)  using 1:2:3 w l lt 3
        set view 69.867, 100.267, 2.503 
        pause 0.05
        break # however: conditionally, on key pressed
     }
  }
}
# break to here

Answer 1

勾选help bind。可能，您正在寻找这样的东西。当按下 x 时，循环将停止。

代码：

### key bind
reset session

bind "x" "Stop = 1"
Stop = 0

do for [i=1:1000] {
    plot sin(i/20.*x)
    print i
    pause 0.25
    if (Stop) {Stop = i;  break}
}

if (Stop) { print sprintf("Stopped after %d iterations", Stop) }
else { print "Time is over..." }
