The print() variables, as stated in this website, shows that the print summary can be done once a data is read in and has a reference f. I wonder if this can be used after I used an array that gets the variable and maybe another that process the data again once getting the variables from f? In the old ncl, printVarSummary can basically be used anywhere and any array, not restricted to a reference variable in f. Can this work for Nio?<div><span style="white-space:pre-wrap"> </span>yours,</div><div><span style="white-space:pre-wrap"> </span>Jinbo<br><br><br><blockquote name="replyContent" class="gmail-m_-7576767151873302430ReferenceQuote" style="padding-left:5px;margin-left:5px;border-left:2px solid rgb(182,182,182);margin-right:0px">-----原始邮件-----<br>
