[ferret_users] How to get pressure axis variable in reverse order



Hello Ferret Users,

I have ASCII file, I am reading it like :-



define axis/t=1:43:1 time_grid

define grid/t=time_grid newgrid


file/var="p,w1,w2,w3,w4"/grid=newgrid\
"data.dat"



     currently SET data sets:
1> ./test_transp.dat  (default)
 name     title
                    I         J      K     L
 P        P
...       ...       ...                  1:43
 W1       W1
...       ...       ...                  1:43
 W2       W2
...       ...       ...                  1:43
 W3       W3
...       ...       ...                  1:43
 W4       W4
...       ...       ...                  1:43


The first variable is pressure (P) which has
velues in hPa. When I plot

plot/vs w1,P

then the pressure is reversed on y-axis, i.e.
1000 mb is on top and 10 mb in bottom.

Kindly help how to use the 'depth' command to
make y-axis as decreasing from bottom.

If we can define the axis in other way to
reverse the current y-axis order.

Many thanks,

Regards,
Yogesh
