<br>Thanks, but it must be something different. I have !x.style=1 &!y.style=1.
BTW I'm using PV-WAVE 7.0.

<p>You are running into IDL's very persistent aesthetic
<br>sensibilities about what constitutes "nice-looking"
<br>axes. You have to hit it upside of the head. Try
<br>setting the XSTYLE and YSTYLE keywords to 1. :-)
<p>Cheers,
