<div>Hi Stuart,<br>
<br>
in your script you are opening a GFS control file... Replace with (I suppose) ecmwf_grib.ctl . And I can't see where you change the t (time), Can you please show me the rest of your script?<br>
<br>
Regards,<br>
<br>
Marian<br>

<p style="">Hi all,</p>
<p style=""><br>
</p>
<p style="">I'm currently developing charts using ecmwf free data but I'm having an issue with the time steps. The first image is fine but the rest of the time steps use the same data as the first one. The charts are not running in sequence. Can anybody advise
where my issues are. I've attached parts of my control file and script to assist. </p>
