Problem with linear plot for time series

[Daniele Gandini]

Hello.

Try using template option in your ctl file which allow
to manipulate separate grib files with only one ctl file.

Example: I have 20 files corresponding to different analysis instants

ECMWF0250_20060805.ctl
ECMWF0250_20060805.gmp
ECMWF0250_2006080500.grb
ECMWF0250_2006080506.grb
ECMWF0250_2006080512.grb
ECMWF0250_2006080518.grb
ECMWF0250_2006080600.grb
ECMWF0250_2006080606.grb
ECMWF0250_2006080612.grb
ECMWF0250_2006080618.grb
ECMWF0250_2006080700.grb
ECMWF0250_2006080706.grb
ECMWF0250_2006080712.grb
ECMWF0250_2006080718.grb
ECMWF0250_2006080800.grb
ECMWF0250_2006080806.grb
ECMWF0250_2006080812.grb
ECMWF0250_2006080818.grb
ECMWF0250_2006080900.grb
ECMWF0250_2006080906.grb
ECMWF0250_2006080912.grb
ECMWF0250_2006080918.grb

Here the relevant rows the ctl file:

dset ^ECMWF0250_%y4%m2%d2%h2.grb
index ^ECMWF0250_20060805.gmp
undef 9.999E+20
title ECMWF0250_2006080500.grb
* analysis 2006080500 analysis_only 0 hr
*  produced by grib2ctl v0.9.12.5p10
dtype grib 255
options yrev template

Bye

Hello,

I have the following problem: I'm trying to plot time series for a fixed
location (X,Y) and level (Z), but it doesn't work. The data I have is
contained
in a series of separate grib files, one grib file for each instant of the
series. I open these files prior to dimensions fixing and draw command.

The reason seems to be, that data is in separate files, and grads can't
associate time series with the file series. Could I ask for confirmation (or
denial) of this hypothesis?

How could I overcame this problem?

(Pardon for such basic questions, but the way grads associates time with
files
is still a mystery for me.)
