Creating plots with NetLogoWeb

[Eva Ravnikar]

Dear netLogo users

I'm new to netLogo and I'm trying to understand and recreate some "Wolf Sheep" models that can be found in the NetLogoWeb version. Admittedly, I haven't studied all the information available online, but I have spent some time searching for my specific question.
As I want to use NetLogoWeb with my secondary school students, I am sticking to the NetLogoWeb interface to avoid the need for a full NetLogo installation. Also, I'm building the model "from scratch" and would like to add:

A) "go" and "setup" buttons
B) some plots for the number of sheep and wolves

Is it at all possible to add buttons and use "plot" commands in the web version?
I haven't found a way to add buttons and when I try to add plot commands I keep getting an "error while running SET-CURRENT-PLOT" error and I can't find any explanation of how to solve it.

My procedure is as follows:
1) I defined wolf and sheep breeds and let sheep die in some simulation steps.
2) I use the command interface by running setup (once) and go (several times). I would like to do this by clicking a button, but there seems to be no way to do this in the web version.
3) I want to plot the number of sheep using commands such as..
set-current-plot "Sheep"
set-current-plot-pen "Sheep"
plot number of sheep
.. but I always get an "error while running SET-CURRENT-PLOT", no matter where I call the plot-related procedures.

Many thanks for any little hint.

Regards, Eva
