[Met_help] [rt.rap.ucar.edu #81644] History for Adjusting Line Widths on Reliability Diagrams

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

Hi,

I was wondering if it is currently possible to adjust the line width of the
max skill line on reliability diagrams.  I tried to make it larger by
setting lwd = 3 in the Rscript (see below).  I ran the Rscript on the NCEP
METViewer server but the line width stayed the same - an example plot is
attached.  I also tried changing the color from gray to black just to see
what would happen but the line remained gray.  Perhaps these settings
cannot be modified or they are being overwritten somewhere?

# draw the max-skill line
abline(
a=0, # intercept
b=1, # slope
lty=1, # line type - 0: blank, 1: solid, 2: dashed, 3: dotted, 4: dotdash,
5: longdash, 6: twodash
col="gray", # line color
lend=1, # line end style - 0: rounded, 1: butt, 2: square
cex=1, # line magnification
lwd=1.5, # line width
xpd=FALSE # plot clipping - FALSE: plot, TRUE: figure, NA: device
);

I was also interested in increasing the line width of the reliability
curves themselves to ~5 but it looks like the largest they can be increased
to is 3.

Thanks!
Ben Blake

Ben,
METViewer doesn't allow to adjust the max-skill line properties with
UI or XML file.
Rscript is the only place to do that.
You should be able to  change the color and width of the line with
your modifications:
col="black",
lwd=3,
And, of course, you need to rerun Rscript:
Rscript <rscript_file.R>
The new image should be where 'strPlotFile' variable points to.
If it doesn't work please send me the path to your Rscript  - I will
take a look.

Rscript that creates the reliability plot prevents to draw plot lines
wider than 3. You can change it by changing the value of "listLwd"
variable and comment out this line in Rscript:
listLwdLeg[listLwdLeg > 3] = 3;

Hi Tatiana,

I'm not sure what I did wrong the first time with the max-skill line
but
after I downloaded the R script from the METViewer GUI and tried
running it
again with those modifications I got it to work.  I attached an
example
plot.

I was also able to increase the line widths to 5 by commenting out
that
listLwdLeg line.

Thanks for the help!
