Find MAX in datafile (e.g. say it was 69) <br>
Round up to the next multiple of CON(1) (70 in this case). <br>
Contours start at 70 (but you will not see this one) and go down in steps of 5
[= CON(1)] for 6 contours. The lower limit will be 0 [= CON(2)]. Thus, if max
was 14, contours would be >10, 5, <0. <br>

Contours start at this value and go up in steps of 10 [= CON(1)] for 6
contours. The upper limit is 200 [= CON(2)]. <br>
code=3 is opposite of code=1, and is used for values that are really negative,
but are calculated as positive values (such as LOSS & RPWRG).<br>
