<div dir="ltr">Hi Zachary,<div>NCL will only color a grid box (when cnFillMode = "AreaFill"; the default) if a fair number of surrounding points have valid values. This allows NCL to draw the filled fields with slightly smoothed contours, taking into account the values of the surrounding grid boxes. If instead, you want NCL to color each grid box individually, and not taking into account the neighboring grid boxes, you should set cnFIllMode = "RasterFill".</div><div><br></div><div>If this is not what you are looking for let the ncl-talk email list know.</div><div>Adam</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Sep 17, 2017 at 1:15 AM, FUNG Yik Him, Zachary <span dir="ltr"><<a href="mailto:yik_him@yahoo.com.hk" target="_blank">yik_him@yahoo.com.hk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello all,<br>
<br>
I wish to make a color-filled contour plot with ncl and the given data-set spreads on an area much larger my plot domain (but they are quite scattered).<br>
<br>
I tried to set "mpLimitMode" to "Corners" to limit the plot area. However, seems that ncl is not considering points outside my plot domain when I am using gsn_csm_contour_map so there is a large area near boundary considers as no data.<br>
<br>
May I know if there is any way to force ncl to consider also data lying outside my plot domain (but cut the unwanted part at the last stage)?<br>
<br>
Thanks,<br>
Zachary<br>
