<p>Hi Lyndz,</p>
<p>There is a GrADS command w2xy that should take world coordinates
as input and return inches on the page. So, in your example below
if you enter:</p>
<p>ga-> q w2xy 00Z01AUG2019 10</p>
<p>where 00Z01AUG2019 is time and 10 is latitude 10N. GrADS will
return the location on the page, which you can then use in drawing
a symbol using "draw string".</p>

<div dir="ltr">Dear GrADS experts,
<div><br>
</div>
<div>I have a time (x-axis)--latitude (y-axis) plot.</div>
<div>The dates ranges from January 1 o December 31.</div>
<div><br>
</div>
<div>I want to draw a symbol at, say, 10N and at August 1.</div>
<div>Is there a way to accurately access the correct
x-coordinate of a specific date in this kind of plot?</div>
<div><br>
</div>
<div>I'll appreciate any help.</div>
