<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Dean, <DIV><BR class="khtml-block-placeholder"><DIV>Thanks for the reply. I'm probably using this widget incorrectly, but what I want is a small set of 3D axes in the lower left hand corner, like Paraview has. I don't want any sort of axes around the data. The issue is, I can produce the small set of axes in the corner just as I want them (small, non-interactive, etc), but I also have a set of axes drawn near my data set. Actually, what VTK draws is really tiny axes with huge axes labels. Calls to SetFontSize( i ) have absolutely no effect (although I can change the font type, bold, italicize, etc: I'm running VTK with Carbon on an Intel MacBook Pro, I figure this is just a bug). Here's my code (I'm just starting out at VTK...).</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>...</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px;
