<div dir="ltr"><div>Hi Zoe,</div><div><br></div><div>I should have initially asked what version of NCL are you using (command "ncl -v")? I am not getting that warning message, using the latest v6.6.2. I get the attached plot (note, I don't have the RANGS database handy, so it's not using the HighRes map database).</div><div><br></div><div>I also had to add a "draw(plot)" statement after the call to wrf_map_overlays(). I'm not sure what you intend there in that loop "do i=0,ntimes-1,2", whether there should be multiple plots or a panel plot? Just a side comment, since "opts" doesn't change each time through the loop, you could factor the settings outside the loop, and thus not reload the colormap each time. <br></div><div><br></div><div>Not sure what to tell you about the warning message.</div><div><br></div><div>Rick</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, May 10, 2021 at 8:56 AM ZUO Ziping <<a href="mailto:zzuoaa@connect.ust.hk">zzuoaa@connect.ust.hk</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<div>Hi,</div>
<div><br>
</div>
<div>I looked at the code where the error message arises, and this is indeed a bit of a mystery. If you might send me one of your WRF files, I'll try to run the script in the debugger to get a better idea of whats going on.</div>

The other day when I was trying to use the colors in the "<b>BlGrYeOrReVi200</b>", I use the <b>res@cnFillPalette = "BlGrYeOrReVi200"</b>. However, it kept reminding me "<b>warning:ContourPlotSetValues: color index (204) exceeds size of palette, defaulting
to foreground color for entry (12)</b>".</div>
