<div dir="ltr">Hi Jason,<div>Thank you for providing the script and data file. I see a few issues:</div><div>- I merged parts of your 1st script with your second script, as the 2nd script didn't have ntStrt/ntLast set.<br>- Your y array is mostly filled with _FillValues, and trend_manken does not allow missing values.</div><div>- y@_Fillvalue = -999 should be y@_FillValue = -999</div><div>- For this line: dplt = new ( (/ny,nrow/), typeof(y), y@_FillValue), nrow is a 2D array, and that's why you are getting your first error message. (I swapped nrow out for 11323, but not sure if that's what you want.)</div><div><br></div><div>As your data is mostly missing, I am unsure what to suggest if you really want to use trend_manken. If all you want is a linear trend line, you can use <a href="https://www.ncl.ucar.edu/Document/Functions/Built-in/dtrend_msg_n.shtml">dtrend_msg_n</a> and the returned slope/y_intercept attributes to construct a trend line for your data. <br></div><div><br></div><div>Hope that helps!</div><div>Adam</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 8, 2022 at 6:49 AM Herb, Jason via ncl-talk <<a href="mailto:ncl-talk@mailman.ucar.edu" target="_blank">ncl-talk@mailman.ucar.edu</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">

I am trying to put a trend line and associated trend text information on my plots. I am getting the following errors when attempting to plot. Script is attached and a sample file. Any suggestions?<br>
