min and max contours

[Glenn Carver <Glenn.Carver@xxxxxxxxxxxxxxxx>]

I've hit a problem with ferret that I've not had a problem with before.
Ferret differs somewhat from other plotting packages I used when it comes
to how it deal with the minimum and maximum contour.

Suppose I specify a min. contour at 0 and a max.contour at 10, with an 
interval of 1. Ferret will contour 1->2, 2->3, ... 9->10.

However, what I need to be able to do is :

  minvalue -> 1, 1->2, 2->3, ... 9->10, 10->max value.

My problem is that I'm comparing plots from different models and I need
to use the same scale. With data that goes outside the range 1->10 (say), 
Ferret leaves it blank. Programs like GrADS or gsharp will contour from
min->max with a specified set of levels and I need to be able to do the
same with Ferret. I've been through the documentation but I don't think
it's possible?   If not, can I get it put on the to-do list??

Thanks
