Hello. I'm trying to do a batch plot of a time series using "forecast
valid time" as independent variable, and am not sure how to specify the
independent variables without spelling out all the forecast valid
times. In the attached three files, the 1st and 2nd are the *.png and
*.xml of the interactive METviewer plot - the *.xml spells out the
Independent variables (a full list of valid times):
<indep equalize="true" name="fcst_valid_beg">
<val label="2019-08-01 12:00:00" plot_val="">2019-08-01
12:00:00</val>
<val label="2019-08-02 12:00:00" plot_val="">2019-08-02
12:00:00</val>
....
<val label="2019-10-13 12:00:00" plot_val="">2019-10-13
12:00:00</val>
<val label="2019-10-14 12:00:00" plot_val="">2019-10-14
12:00:00</val>
</indep>
How should the above be handled in a batch job? When the forecast valid
time is not an independent variable (merely a fixed variable), I'd do
<date_range name="vtimes">
<start>2019-08-01 12:00:00</start>
<end>2019-10-14 12:00:00</end>
<inc>86400</inc>
<format>yyyy-MM-dd HH:mm:ss</format>
</date_range>
then later
<plot_fix>
<field equalize="true" name="fcst_valid_beg">
<date_range name="vtimes"/>
</field>
.....
</plot_fix>
The attached plt_rmse.xml was my first attempt at making the time series
plot in batch, and the independent variable set up obviously needs more
work, but I can't figure out how to properly "unroll" the specified
<date_range name="vtimes"> to create the equivalent of the above
independent variables list.
Thank you very much -
Ying

Ying,
<date_range> doesn't work for the independent variables. You should
use <date_list> instead.
In plt_rmse.xml:
- remove <date_range...
- instead of <date_range name="vtimes"/> under <indep> put:
<date_list>
<start>2019-08-01 12:00:00</start>
<end>2019-10-14 12:00:00</end>
<inc>86400</inc>
<label_format>yyyy-MM-dd HH:mm:ss</label_format>
</date_list>
Please notice <label_format> and not <format>
