<div dir="ltr">Oh...in that case use a while loop to build a text string adding each contour level. Here's a simplified example from one of my own scripts:
<div><br>
</div>
<div>
<div> c_levs = '' </div>
<div> c_cols = '' </div>
<div> value = min_deg </div>
<div> init_color_value = 16</div>
<div> i = 0 </div>
<div> while (value <= max_deg)</div>
<div> color_value = math_int(init_color_value + i*skips)</div>
<div> i = i + 1 </div>
<div> c_levs = c_levs' 'value</div>
<div> c_cols = c_cols' 'color_value</div>
<div> value = value + diff </div>
<div> endwhile </div>
<div>* These two lines are required since set ccols requires one more value than set clevs</div>
<div>* at this point, i should be equal to n_levs</div>
<div> color_value = math_int(init_color_value + i*skips)</div>
<div> if (color_value > 69)</div>
<div> color_value = 69 </div>
<div> endif </div>
<div> c_cols = c_cols' 'color_value</div>

<div> 'set ccols 'c_cols</div>

<div>Hi Jeff,</div>
<div><br>
</div>
<div>Thanks for the response. I have the RGB values and the 'set ccols' command covered I think. Those will remain static no matter what the high/low temps are. I'm looking for how to work the 'set clevs' command, which I need to be variable from data file
to data file, given that the temperature ranges will change. So, I'm wondering if I can create an array of clevs, and pass that to the 'set clevs' command.</div>

<div dir="ltr">You need to also set the contour colors. This means you will need to use the 'set rgb R G B' commands to define color numbers up to 255 (the highest allowable in Grads) and set the color values using the 'set ccols (list#)'.

<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>
