[McIDAS #ITE-161076]: Plotting satellite derived winds in McIDAS

Hi Carol,

re:

> California. What do you think? Maybe I'm plotting the numbers a bit too big.

The size of the various items is, quite frankly, a matter of taste... I
think the sizes are fine.  I do have a problem seeing the dark blue on
top of a black background, however.

re:
> Also, how do I fixed the labels at the bottom?

I think you are referring to the dark blue line of text overlaying
one of the other ones, correct?

The only way I know of controlling where your labels are written is to
use the ** undocumented ** TITLE= keyword which is passed on to PTDISP
which does the actual plotting and labeling.

To see what one can specify as values in a TITLE= keyword clause, list
out the HELP for PTDISP:

HELP PTDISP
PTDISP -- Displays point data
   PTDISP dataset frame <keywords>
Parameters:
   dataset | ADDE dataset name and position; specify as alias.position or
             group/descriptor.position where position is a positive integer
             (absolute position), 0 or a negative integer (relative
             position), or ALL (no def for group/descriptor or alias;
             position def=ALL if DAY is specified in SELECT keyword,
             otherwise def=0)
   frame | frame number or OPP (opposite) to display output (def=current)
Keywords:
 ...
*****************************   Plot Keywords  ***************************
   COLor=c1..cN | graphics color level for each PARAMeter (def=3);
                  each of the c1..cN values can be specified as a single
                  number, e.g., COLOR=3 5 6, or in format col[min-maxBinc]
                  to assign multiple colors for the parameter, based on
                  its values; see the Remarks for details
 ...
   TITLE='text' color line ele size |  text, color, location & size for
                                       title, where:
                'text' - title's text; 72 characters maximum; specify X
                         without quotes for default text (def=computed)
                color - graphics color level of title (def=value specified
                        in COLOR keyword)
                line - beginning TV line to write title (def=lower-left
                       corner of frame; exact line number depends on frame
                       size and value specified in COLOR keyword)
                ele - beginning TV element to write title (def=20)
                size - pixel size of characters drawn (def=8)

One specifies TITLE= if s/he wants to take over complete control of the
labeling of the plot.  To get a rough idea of how this works, try the
following:

SF 1
ERASE F
SFCPLOT T CO

SF 1
ERASE F
SFCPLOT T CO COL=4 TITLE='T[F]' 4 850 50 10

The first SFCPLOT invocation uses default choosing of T's color
and plot label.  The second invocation says to plot T in color
level 4 and write the label in color 4 at LIN,ELE 850 50 and make
the label size 10.

NB: the specification of LIN and ELE will depend on the size of
the frame in which you are trying to produce the plot.  The
frame I was using for a test is 950 lines by 1500 elements.  If
your frame size is smaller, you will need to reduce the LIN and
ELE you specify in your TITLE= keyword clause to match your frame
size and where you want the label to be written.

Give the above a try and then play around with specifying where your
want your label written.

Cheers,

Tom
