Hi,

Is there an available option  to display the "mean value"  in the plot?

thanks,

Alvin,

I see that you have a question about plotting in MET.  You're
wondering how
to display the "mean" value in a plot.

I'm not exactly sure what plot you are referring to, but my guess is
that
you're talking about the output of the plot_data_plane utility in MET.
If
that's correct, the answer is no, plot_data_plane doesn't compute any
summary information about the data it is plotting.

However, you may find the grid_stat tool to be useful.  It is used to
compare one field of gridded data to another field and derive summary
statistics.  The statistics are sorted into groups and written out
into
different line types.  The CNT line type contains "continuous"
statistics,
one of which is called FBAR which is the mean forecast value.

So MET certainly has the ability to compute mean values... but not
within
the plot_data_plane tool.

Hope that helps clarify.

Thanks,
John

Hi john

Im referring to the met_ tc plot.For example , the line graph for
track
error. It can display the number of samples, but is there a way to
display
the mean value for track error in the graph?

Alvin,

Ah, ok.  I understand your question now.

Yes of course, you can easily edit that plot_tcmpr.R script in
whatever way
you'd like.  Most of the MET tools are compiled code, but the Rscripts
can
easily be edited by the user.

The plot_tcmpr.R script actually calls the functions defined in
met-5.2/scripts/Rscripts/include/plot_tcmpr_util.R.  Specifically, the
function named "plot_valid_counts" on line 896 of that file tacks on
the
sample size.

Please feel free to edit these scripts in whatever way you see fit.

Hope that helps clarify.

Thanks,
John
