[Met_help] [rt.rap.ucar.edu #95910] History for lack in date_list (date_range_list) understanding

  Initial Request
----------------------------------------------------------------

Good morning,

I thought that I understood how to use the date_list as a shorthand option
for constructing the dates that should be grouped.  I'm in the process of
using a python script that I wrote to change my independent variable from
fcst_valid_beg to fcst_lead.  The construct of the xml looks exactly the
way I had imagined it.  I also group the following into fix fields:
fcst_init_beg, fcst_valid_beg, and vx_mask.  In metviewer the result would
look something like this (attachments 1 for plot and 2 for its xml file).

When I try to reproduce this result I get something like this (see
attachments 3 for plot and 4 for xml).  The only differences in the xml are
how I set the date.  You can see that in attachment 4 I use date_list for
both fcst_valid_beg and fcst_init_beg.  I then use idates and vdates in the
fix fields below.  Despite doing this, I get the plot that you see in
attachment 3, which I don't understand.

Hi Edward

I see a couple errors in your not_working.xml file

- for idates you have <inc> commented out. It should be uncommented:
 <date_list name="idates">
        <start>2020-07-09 06:00:00</start>
        <end>2020-07-11 12:00:00</end>
        <inc>21600</inc>
        <format>yyyy-MM-dd HH:mm:ss</format>
    </date_list>

- you need to add <set> elements  to plot_fix :
<field equalize="false" name="fcst_valid_beg">
   <set name="fcst_valid_beg_1">
        <date_list name="vdates"/>
   </set>
</field>
<field equalize="false" name="fcst_init_beg">
   <set name="fcst_init_beg_1">
         <date_list name="idates"/>
   </set>
</field>

Give it a try and let me know if you still have problems.

Tatiana

Hmm.  Sorry for missing that.  I have made those changes but can't
test it
until the network issues get resolved
