You would type 'd temp*0' (without quotes). You can control its thickness and appearance using the normal attributes (set cthick, etc.), prior to display.</div>

Dear GrADS users,<br>
<br>
I have plotted an area averaged temperature anomaly (let say) with<br>
time in GrADS and wanted to make zero line visible on y axis so that<br>
my graph clearly tell how many values of my plotted line are above and<br>
below zero line on the y axis. How to do that?<br>
<br>
Thanks,<br>
<br>
Mubashar<br>
