<div dir="ltr"><div class="gmail_default" style="font-size:small">The issue is that NCL can't make any assumption on what the X or Y axis should look like outside the actual X/Y range of your data. If you give it extra values on either axis, and your data is irregularly spaced in either axis, then NCL can't "guess" at what the new values should be spaced as.<br></div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">One way around this is to increase your data array's dimensions by the desired new values, using the "new" function to increase the two coordinate arrays and the data array as desired.
