Cool. That's very elegant. I don't know why I didn't think of it myself.

Hi Mark --

Every Etoy object has a pen (they are all "turtles with costumes"). So instead of having an opaque plotting feature, we just have the kids use a small object (like an ellipse), put the pen down and write a ticking script like

        ellipse's x increase by 1
        ellipse's y <- <the value to be plotted>

This is nice and simple, and also makes plotting understandable.

Cheers,

Alan

The project refers to making a line plot, but doesn't go into any detail. Is there a mechanism for plotting or graphing data within etoys, or are you supposed to construct a plot using some different tool?

Thanks,

Mark
