The units for time say "hours since 1800-1-1 00:00:00" so if the interval is like 1 hour, then changing the y-axis tick interval from 5 hours to 10 hours, for example, is likely not going to change the locations of the tick marks much nor their labels.<br></div>2) If (1) doesn't help, have you tried using 'set yaxis' instead?<br><br></div>Jeff Duda<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jan 26, 2018 at 7:40 AM, Lyndz <span dir="ltr"><<a href="mailto:olagueralyndonmark429@gmail.com" target="_blank">olagueralyndonmark429@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Dear GrADS experts,<div><br></div><div><br></div><div>I am trying to modify the interval of the y-axis in the attached time-longitude plot.</div><div><br></div><div>[1] I tried to change the 'set ylint' line in my script but <b>the label interval does not change</b>.
