我编的程序如下turtles-own [energy]
to setup
  clear-all
  setup-patches
  create-turtles 100
  do-plots
  ask turtles [ setxy random-xcor random-ycor ]
end
to go
  move-turtles
  eat-grass
  reproduce
  check-death
  regrow-grass
  do-plots
end
to move-turtles
  ask turtles [
right random 360
forward 1
set energy energy - 1
]
end
to setup-patches
  ask patches [ set pcolor green ]
end
to setup-turtles
  create-turtles 100
  ask turtles [ setxy random-xcor random-ycor ]
end
to eat-grass
  ask turtles [
if pcolor = green [
   set pcolor black
   set energy (energy + 10)
   ]
ifelse show-energy?
   [ set label energy ]
   [ set label "" ]
]
end
to reproduce
  ask turtles [
if energy > 50 [
   set energy energy - 50
   hatch 1 [ set energy 50 ]
   ]
]
end
to check-death
  ask turtles [
if energy <= 0 [ die ]
]
end
to regrow-grass
  ask patches [
if random 100 < 3 [ set pcolor green ]
]
end
to do-plots
  set-current-plot "Totals"
  set-current-plot-pen "turtles"
  plot count turtles
  set-current-plot-pen "grass"
  plot count patches with [pcolor = green]
end
可是运行时提示no such plot: "Totals"
error while observer running SET-CURRENT-PLOT
  called by procedure DO-PLOTS
  called by procedure SETUP
  called by 按钮 'setup'
求大神解答啊

no such plot: "Totals"，就是说你的界面里没有叫做Totals的绘图框

建一个叫做叫做Totals的绘图框就行了

哦，知道了，虽然自己应经找到问题了，不过还是谢谢哈

你也可以直接再界面页创建“绘图”，然后设置时钟(ticks)，每一步画一次，不用自己操心。
