<p>Thank you, Jeff. I actually solved the issue after sending the email-go figure! Apparently I had not tried 'set lon 60 420' etc, I had only tried 'set lon -60 300'. The former method works! To get the map centered at the Greenwich Meridian as opposed to
the dateline, it just requires 'set lon 180 540', and ta da, it works. Really cool.</p>

</p>
<p>The only remaining issue is with the land polygon for plotting SSTs (lpoly_mres.asc). The lpoly will not draw outside of 0 to 360. So, a plot starting and ending at 180° (centered about the Greenwich Meridian) will only draw the polygon from 180 to 0 on
the western half, and won't draw for the remaining eastern half of the figure. Any ideas on how to address this problem? </p>

<p>Cheers,</p>

<p>Hi,</p>
<p><br>
</p>
<p>I am working with ERA Interim reanalysis data and NOAA SST data, which start at longitude 0 and run to 360. The grads default lat/lon grid centers this data about the dateline/180 degrees. I would like to have the plot begin from say 60°E and run around
the full 360 degrees, so centered at 60°W/240°E. I have tried to achieve this two ways: set the longitude values to 60 420 and -60 300. However, the data is cut off and is no longer continuous. Is there an alternative way to change the plot so that it is centered
at a different longitude value, but remains continuous around the globe? It works fine in mproj sps format, but I would like to keep the mproj in the default lat/lon grid.</p>
<p><br>
</p>
<p>Any help or suggestions would be appreciated.</p>
<p><br>
</p>
<p>Regards,</p>
<p>Kyle </p>
