Re: [ferret_users] how to replace missing value with any string inlabel command

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi -
You can do this with an IF statement.  Try the example below, which puts 
a symbol at some points along the line y=40, and then labels them.  The 
clause

   if `slp[l=1,y=40]`

will be true if the variable has good data at that location; if slp is 
missing there then the ELSE will be executed.

 yes? SET DATA coads_climatology
 yes? SHADE/L=1 slp
 yes? repeat/x=20:300:50  (plot/vs/nolab/sym=27/over `x`, 40;\
    if `slp[l=1,y=40]` THEN \
    label `x`,42,0,0,0.12,"`slp[l=1,y=40]`" \
    ELSE  label `x`, 42, 0, 0, 0.12, "land")

 Dear Sir

I found some FAQs on how to change missing value.
However, I would like to know how to change other strings
label with "bad" of missing value in "label" command.

When I try to "label" the values of sst with a missing
value of -1e34, the label command shows "bad" label on the
missing values. After I replace a missing value using
missing function, for example,
let sstnew=missing(sst,-99.9). 
Of course the "label" comand can draw the "-99.9". 
I would like to change, for example, "bad" with "land".
Could somebody tell me how?


Best Regards,

Takaya Namba
