Hi,
In Ferret these computations are done by means of "Transformations".  See that section in Chapter 3:
../../documentation/users-guide/variables-xpressions/XPRESSIONS.html#_VPID_148

Please have a look at that documentation, and you are welcome to write back to the list when you have had a chance to try it out.

Hi All,

I wanted to compute mean, standard deviation and root mean squared deviation for a data which is monthly in form of NC file so could you please help me with the script for the same, the data is as follows,:
     currently SET data sets:
    1> ./7E62F7080D407221D60CE03BA5A1DA72_ferret_listing.nc  (default)

Thanks for your kind help, Is there is any way out to define a region in between the shaded plot like if I am plotting the Indonesian flow and i want to specify something on the shaded region is there is any way to do so,

Hi,
There are two methods here.  One is

shade/nolabel

which removes all the labels except the axis labels. That's sometimes ok, but usually you want to be more selective in which labels are removed.  Automatic labels that document the variable, region and dataset are highly useful, but you might want to customize what's on the plot.

To get rid of the little lines in the upper right, called the "ferret logo", you can issue this command, which takes effect for the rest of the Ferret session, or until you undo it:

CANCEL MODE LOGO

The topic, "removing movable labels" ../../documentation/users-guide/customizing-plots/LABELS.html#_VPID_236 discusses the whole topic.  So for instance,

use monthly_navy_winds
cancel mode logo
shade/t=1-jan-1990/x=300:350/y=-20:20 uwnd

yes? sh sym *lab*
LABX = "LONGITUDE"
LABY = "LATITUDE"
LABTIT = "ZONAL WIND (M/S)"
LAB1 = "TIME : 17-DEC-1989 09:30"
LABNUM_T = "1"
LAB2 = "DATA SET: monthly_navy_winds"
LABNUM_DSET = "2"
LAB3 = ""

So, you can run "go unlabel" and get rid of any of the labels LAB1, LAB2, etc.  The symbols LABNUM* are listed here,

../../documentation/users-guide/customizing-plots/SPECIAL-SYMBOLS.html#Chapter6 Ferret special symbols

shade/t=1-jan-1990/x=300:350/y=-20:20/set uwnd
   go unlabel ($labnum_t)
   go unlabel ($labnum_dset)
 ppl shade

Hi Folks,

I have a plot now i would like to modify the HEADINGS on the plot for example if i am plotting the data as:
    4> ./pottmp.2008.nc  (default)
 name     title                             I         J         K         L         M         N
 DATE                                      ...       ...       ...       1:12      ...       ...
 TIMEPLOT                                  ...       ...       ...       1:12      ...       ...
 POTTMP   Potential temperature            1:360     1:418     1:40      1:12      ...       ...
 
yes? shade/I=15:150/J=30:250/K=6/L=6 POTTMP

 now the shaded plot has some headings as : At top : Depth, time and the version of the ferret i am using, so is there is any ways by which i can edit these heading which are there on the plot.

And for the over lay plot please tell me that how i can define the plots for three different data and can give different colours to them.
