<p>Hello <br>
</p>
<p><br>
</p>
<p> I am wondering if NCl provide a smooth option for xy plots like Excel: <br>
</p>
<p><img size="0" contenttype="image/png" style="max-width: 99.9%; -moz-user-select: none;" id="img533841" crossorigin="anonymous" aria-expanded="false" tabindex="0" src="cid:a655862b-56fe-412f-b91d-e01e8a4459f9"></p>
<p>In NCL, it seems only straight lines are allowed between data points. <br>
</p>

</p>
<p>Thanks</p>
