Re: Re: label the value of a nunmber variable
I tried as Arindam told me, but i'm informed as below:
%LABEL/nouser 6.1,1.84,-1,0,0.16
~'corr'
Symbol not found
My *.jnl file is :
set view
v11
let
cave=coral[d=1,l=1:191@ave]
let
cdif=coral[d=1,l=1:191]-cave
let
cdif2=cdif*cdif
let
csum=cdif2[l=1:191@sum]
let
sc=(csum/190)^0.5
let
stdc=cdif/sc
let
save=sst[d=2,l=1:191@ave]
let
sdif=sst[d=2,l=1:191]-save
let
sdif2=sdif*sdif
let
ssum=sdif2[l=1:191@sum]
let
ss=(ssum/190)^0.5
let

let

let

let
corr=aa/190.
list

let

let xlev=if(l eq 1)then `($XAXIS_MIN)` else
`($XAXIS_MAX)`
let

Ferret
version i'm using is 5.53. Can anyone tell me why and how to label value of
"corr"?
hi Gao,
the value of a scaler variable is obtained by enclosing it in
the back-quotes as `variable_name`. Now if you precede this by a ~
character, it'll become a string and you can use it in a label
command. Moreover, you can use the font specification symbols @XY
where XY is the font type to label the value of that variable.
Here's one example:
! make a sine plot
plot/x=0:360 sin(x*3.1415/180)
! we'll label this variable
let corr = 12/190
! label it, using the default font and precision
label 250,0.80,0,0,0.13 ~`corr`
! now if you want a different font
label 250,0.70,0,0,0.13 @TR`corr`
! and the precision as per your need
label 250,0.60,0,0,0.13 @TR`corr,p=-3` !p=-3 means the user wants 3
digits after the decimal point.
For more details about font control, look at
http://ferret.wrc.noaa.gov/Ferret/Documentation/Users_Guide/current/Chapter6_Customizing_Plots.htm#_VPINDEXENTRY_762
or precision control, look at
http://ferret.wrc.noaa.gov/Ferret/Documentation/Users_Guide/current/Chapter3_Variables_and_Expressions.htm#_VPINDEXENTRY_517
or label command, look at
http://ferret.wrc.noaa.gov/Ferret/Documentation/Users_Guide/current/Chapter6_Customizing_Plots.htm#_VPINDEXENTRY_721
