If you put the array on a rotator and put a receive antenna with some
sensitive output indicator beyond the near field, you can plot relative
field,

Also, i don't really have a transmitter that I can vary the power that
much...maybe that's something i should make or get. Something variable at
least by 20dB or so.

You don't need to pump power to measure antenna patterns. A simple signal
generator with a milliwatt or so will work fine. If you want to be really
serious about designing antennas, then you need to start acquiring serious
tools. See eBay; start bidding on a sig gen, some pads (attenuators), a
rotor, a field strength meter.
