如何正确绘制变量

问题描述

我试图研究文档，但没有找到所需的答案.所以我在这里问:

I tried to look into docs, but I haven't found the answer that I needed. So I am asking here:

例如，我有15只海龟(此数字可能有所不同)，我需要将它们的变量(例如Revenue)绘制到一个图中.我知道我可以绘制1个代理槽命令的变量

I have for example 15 turtles (this number can vary) and I need to draw their variable (for example Revenue) into one plot. I know I can plot variable of 1 agent trough command

plot [revenue] of turtle 0

但是我该如何绘制整个代理集?

But how can I plot the whole agentset?

我的第二个问题是，当我有乌龟0的命令图[revenue]时，netlogo给我一个错误，该错误是:OF预期的输入是乌龟代理集或乌龟，但没有提示(当我按设置按钮时).如何避免呢?

My second problem is when I have the command plot [revenue] of turtle 0, netlogo gives me an error which says: OF expected input to be a turtle agentset or turtle but got NOBODY instead(when i press setup button). How to avoid it?

谢谢Mestralx.

Thanks, Mestralx.

推荐答案

您可以使用create-temporary-plot-pen快速制作所需数量的绘图笔.就您而言，每只乌龟一只.

You can use create-temporary-plot-pen to make as many plot pens as you need, on the fly. In your case, one per turtle.

这是一个小代码示例.假设我有:

Here's a little code example. Suppose I have:

to setup
  clear-all
  reset-ticks
end

to go
  if ticks < 10 [ create-turtles 1 ]
  ask turtles [ fd 1 ]
  tick
end

现在在我的绘图中，我删除默认笔，并将其放在绘图的绘图更新命令"中:

Now in my plot, I delete the default pen, and I put this in the plot's "Plot update commands":

ask turtles [
  create-temporary-plot-pen (word who)
  set-plot-pen-color color
  plotxy xcor ticks
]

如果我运行它，我将得到:

If I run it I get:
