<code>set cterp <i>on|off</i></code></p><p>
Turns spline smoothing on or off. "Sticks" until reset. Shaded contours
are drawn without spline fitting, so to insure an exact match when
overlaying contour lines and shaded contours of the same field, specify
<code>cterp</code> as off. You can still use the
<a href="http://iges.org/grads/gadoc/gradcomdsetcsmooth.html"><code>csmooth</code></a>
option, which affects both contour lines and shaded contours.</p><div>--Jennifer</div><div><br></div><div><br><div><div>On Jul 25, 2012, at 3:26 PM, Stefan Gofferje wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Hi,<br><br>I'm plotting a parameter first with gxout shade2 and then I plot over it<br>with contour to make some borders better visible.
