<div style="line-break:after-white-space">I’m clearly misunderstanding some of the parameters for floats, pspicture, and \psgrid.
<div><br>
</div>
<div>The code below yields two grids of the same size (with different subdivisions).</div>
<div>Should I have set the two pspicture parameters differently? </div>
<div>From what I understand, </div>
<div>the two pspictures are both 9cm x 9cm boxes, so why are they aligned differently?</div>
