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

let
cave=coral[d=1,l=1:191@ave]
let
cdif=coral[d=1,l=1:191]-cave

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
or precision control, look at
or label command, look at
