Hi, Lyndon —
<div>The values in the “Min, Max” line are the actual extremes of data values in your grid, the “Cmin, cmax, cint” values are what Grads will use for default contour levels. You can use nested minloc(min())/maxloc(max()) functions to find the grid coordinate
of the extremes. Here is an example that mixes world coordinates for X and grid coordinates for T (latitude should be fixed):</div>
<div><br>
</div>
<div>
<div><font face="Courier" style="font-size: 14px;">minlon=0</font></div>
<div><font face="Courier" style="font-size: 14px;">maxlon=5</font></div>
<div><font face="Courier" style="font-size: 14px;">mint=1</font></div>
<div><font face="Courier" style="font-size: 14px;">maxt=3</font></div>
<div><font face="Courier" style="font-size: 14px;"><br>
</font></div>
<div><font face="Courier" style="font-size: 14px;">'set lon 'minlon' 'maxlon</font></div>
<div><font face="Courier" style="font-size: 14px;">'set t 'mint' 'maxt</font></div>
<div><font face="Courier" style="font-size: 14px;"><br>
</font></div>
<div><span style="font-size: 14px; font-family: Courier;">'d minloc(min(tt,lon='minlon',lon='maxlon'),t='mint',t='maxt')'</span></div>
<div><font face="Courier" style="font-size: 14px;">yminloc=subwrd(result,4)</font></div>
<div><font face="Courier" style="font-size: 14px;"><br>
</font></div>
<div><font face="Courier" style="font-size: 14px;">'d minloc(min(tt,t='mint',t='maxt'),lon='minlon',lon='maxlon')'</font></div>
<div><font face="Courier" style="font-size: 14px;">xminloc=subwrd(result,4)</font></div>
<div><font face="Courier" style="font-size: 14px;"><br>
</font></div>
<div><span style="font-size: 14px; font-family: Courier;">'d maxloc(max(tt,lon='minlon',lon='maxlon'),t='mint',t='maxt')'</span></div>
<div><font face="Courier" style="font-size: 14px;">ymaxloc=subwrd(result,4)</font></div>
<div><font face="Courier" style="font-size: 14px;"><br>
</font></div>
<div><font face="Courier" style="font-size: 14px;">'d maxloc(max(tt,t='mint',t='maxt'),lon='minlon',lon='maxlon')'</font></div>
<div><font face="Courier" style="font-size: 14px;">xmaxloc=subwrd(result,4)</font></div>
<div><font face="Courier" style="font-size: 14px;"><br>
</font></div>
<div><font face="Courier"><span style="font-size: 14px;">say 'minloc is at x='xminloc' and t=‘yminloc</span></font></div>
<div><font face="Courier" style="font-size: 14px;">say 'maxloc is at x='xmaxloc' and t='ymaxloc</font></div>

<div><b>Cmin, cmax, cint = -10 6 2</b></div>

<div>The Cmin and Cmax is actually what I was looking for. Is there a way to get their location from the 2D plot? The equivalent grid coordinates?</div>
