<p>Hi all,</p>
<p><br>
</p>
<p>I'm trying to get a map with visually smoother colours. I think it would be nice to increase by a large number the levels used in the gsn_csm_contour function. But at the same time, I still want about 10 ticks maximum on the colourbar. Is there any simple
way to do this?</p>
<p><br>
</p>
<p>Attached is the map I'm working on (1), and the smoother type of map I'd like to produce with NCL (2).</p>
<p><br>
</p>
<p>You can find below an extract of my script.<br>
</p>

</p>
<p>Thank you very much,</p>
<p><br>
