Re: convert Variable into Symbol

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hai Boyin Huang,
                   For getting numeric labels you have to specify either
the font (for example @SR , @CR  etc.) or you have to insert one '~'
before the label as shown below.

Example
-------

fill/i=1:10/j=1:10 i*j
let xx = 100                      ! it is variable only
label/nouser 1 1 0 0 0.12 ~`xx`   ! done ?
label/nouser 2 2 0 0 0.12 @SR`xx` ! ok ?

If you want to do the labelling within a repeat loop, refer this mail in
the archive :

Hope this helps....

With Regards 

Jaison Kurian
