[Gnuplot-info] set xrange from variable

[Boniforti F. <fl...@pi...>]

Hello everybody,

I'm still trying to make successfull use of variables in my gnuplot
script, so I'm asking how it would be possible to do a "set xrange"
using a variable.

I have following variables:

FIRST_DAY=`date -d "-$(($(date +%d)-1)) days" +%Y-%m-%d`
LAST_DAY=`date -d "+1 month -$(date +%d) days" +%Y-%m-%d`

What I need to achieve is to set xrange in between the above two values.
Today it should give:

set xrange = [2009-11-01:2009-11-30]

I tried with

set xrange = [FIRST_DAY:LAST_DAY]

but it doesn't work.

Any help will be appreciated!

Thanks,
Flavio Boniforti
