Hi,
I don't even know if that's the question here, but what I'm thinking is that if this:
works
here to hide/show a line,
then this:
should work
here to show/hide lines and arrows
the difference of course being that the first code uses poly_num, which is taken directly from the
code (because it only needs to show/hide one line at a time) wheras the second uses the xml attribute "category" from here
because it's attempting to hide and show a line with arrows on it (the arrows being in the pts array), both of which share the category attribute.
It's not throwing up any major errors, but it's not working, either... any ideas?
thanks in advance...
