[ferret_users] contour line dissapears when using the shakey to enlarge the color key label

[jean li <xgeast@xxxxxxxxx>]

Dear all:

Here is a script that I found in the ferret archive to create the large color key label. But after the label is enlarged, the contour lines disappear. I tried to do ppl shade/line, but it doesn't work.
Anyone knows how to fix this?

use levitus_climatology
shade/line/key/k=1 temp
ppl shakey ,,.12
ppl shade

Thanks!

Jean
