<div>Hi all,</div>
<div><br>
</div>
<div>I have a grads script that reads satellite data and figures out a temperature range based on the data over an area:</div>
<div><br>
</div>
<div>sstrange = maxtemp – mintemp</div>
<div><br>
</div>
<div>I would like to have 254 levels (colors) between that high and low temp, so I calculate an interval like so:</div>
<div><br>
</div>
<div>interval = sstrange/254</div>
<div><br>
</div>
<div>I have all the colors I need for the set ccols option, however I'm wondering if there is a way to dynamically set clevs based on the high and low temp and the interval. I tried the below, but I don't think it worked:</div>
<div><br>
</div>
<div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">i = 1</span></div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">while (i < 254)</span></div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">clev.i = mintemp+(interval*i)</span></div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">'set clevs 'clev.i</span></div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">i = i + 1</span></div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">endwhile</span></div>
</div>
<div><br>
</div>
<div>I also tried the following:</div>
<div><br>
</div>
<div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">'set cmin 'finallowt</span></div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">'set cmax 'finalhight</span></div>
<div style="font-family: Consolas; font-size: medium; "><span style="font-family: Calibri; ">'set cint 'interval</span></div>
</div>
<div><br>
</div>
<div>But I get a message saying 'Too many contour levels -- adjusting cint'.</div>
<div><br>
</div>
<div>Any ideas if this is possible or how to solve it?</div>
<div><br>
</div>
<div>Thanks and best regards.</div>
