[Met_help] [rt.rap.ucar.edu #93325] History for METviewer plot: problem with using OBS_THRESH as independent variable

Mon Dec 9 10:38:33 MST 2019

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

Hello.  In the attached plot_*.png[xml], for some reason the OBS_THRESH as
independent variable is not in order of magnitude.  I tried editing the
*.xml (tmp.xml) to list the obs_thresh in the right order, but when I
loaded the 'tmp.xml' and plotted it the OBS_THRESH again reverted to the
wrong order.  Is there a way to force the OBS_THRESH to show up in the plot
in the correct order?

This is done on the AWS METplus server.

Thank you -

Ying

Hi Ying,
I'm working on this issue and have a question.

In your example all threshold values have the same sign '>' and the
sorting function would just sort by the numbers.
But what if some of your thresholds have '>=' or '<'. How would you
like to see the result?
Sorting by numbers only:
>0.2 >=1 >1.5 >=2
or sorting by sign and number:
>0.2 >1.5  >=1 >=2

Hi Tatiana,

   Thank you for looking into this!  I try to remember to use the same
">"
(instead of ">=") for various precipitation verifications.  Should I
get
sloppy (will try not to) and have a mixed ">" and ">=", your option 1
-
Sorting by numbers only:
>0.2 >=1 >1.5 >=2
would be the one needed, i.e. as an independent variable, the
obs_thresh
should increase monotonically.

Thanks again -

Ying

Ying,
I deployed METviewer patch to AWS with the fix for threshold ordering.
Could you test it please and let me know if it is working.

Thanks,
Tatiana

Ying and Tatiana,

Just wanted to make a comment on this issue.  I agree that sorting
numerically makes the most sense.  But let's say someone has computed
and
plotted all possible threshold types for values 1.0 and 2.0.  If they
were
to plot them all on the x-axis, I think they should appear in this
order:
   <1.0, <=1.0, !=1.0, ==1.0, >=1.0, >1.0, <2.0, <=2.0, !=2.0, ==2.0,
>=2.0, >2.0

So sort numerically FIRST and then sort by threshold type SECOND, and
in
this order: <, <=, !=, ==, >=, >

Any objections or other perspectives on this?

Of course, the thresholds could be complex types, like "<=1.0&&<=2.0".
But
I'd just sort based on the first TYPE and first VALUE to keep the
logic
simple.

Thanks,
John

Hi Tatiana,
   I tried it out, the OBS_THRESH works perfectly now.  Thank you very
much
for your quick response!  Please feel free to close this ticket at
your
convenience/

Hi John,
   Your order of sorting OBS_THRESH for complex situations makes
perfect
logical sense; for precip though there shouldn't be such a complex
situation (that I can think of right now).  If I had "<1.0, <=1.0"
then
I've been too sloppy in setting up the OBS_THRESH.
