tslg { NOFILE | file.ts [ tslist-options ] } { +options | + } [ psxy-options ]
        Make a plot from the binary file file.ts
        A component of a multi-component files are plotted with the -Llabel option.
        In principle, even ASCII-files can be processed; however, the tslist-options might
        become tedious. A suggestion is to pre-run an ASCII-BIN conversion.
        For appending BIN-files, a tslist-app job must be issued as a pre-runner.
        In ~/TD there is a script tslapp specialized on gravimeter files.
        If NOFILE is specified, the call may just close the current plot (+cont, no +keep).
        This is useful if tslg must be called inside a loop with an unknown number of courses.
        (With +keep +cont you may thus add a legend line.)
        NOFILE can be skipped if the first option is a nontrivial +option

Do you like a plot like this? Then consider tsllg
It was made with
        tsllg -LUL -from 2015,01,01,00,00,00 -ls 32400 -L G+V -L G+B -D +M "A title" +P -

        N.B.: This routine will run in a sub-directory ./plot/ (iff one exists).
        Therefore, file names in the option string have to either anticipate
        the change to a subdir (e.g. edit option -E../deci.tse,L ) or, for
        convenience, the file name can be prepended with `pwd`/

 -tp[dfmt]     - this is a special code not recognized by tslist. Instead, the option is
                 expanded to   -Ft1,f13.6,$dfmt -p2:1,2 -N -n1
                 suitable for t-point files. Default dfmt = f10.2

        Options controlling this very script start with a `+´ sign.
        They must be kept together, i.e. they cannot be mixed with the options to
        neither psxy nor tslist.
        If all-default is intended, a lone `+´ must be given.
        Some options work only in the first (-F-), some only in the last (-L-)
        of a series of tslg invocations.

 +V             - verbose.
 +VV            - verbose with set echo

 +left        -F- draw a y-axis only to the left (intending a +right axis later);
                  default is the same axis left and right.

 +keep          - don't close the plot yet. Additional curves can be added.
                  Take the curve with the widest Y-range first, else you must
                  edit the .tslg file.

 +cont          - continue on a previous tslg plot.

 +first         -
continue on a previous plot drawing a new psbasemap.

 +right         - continue on a previous plot but add a right Y-axis.
                  Only one such extension and ensuing ordinate scaling can be applied.

 +S             - in combination with GMT -Woption: Staircase line (boxcar, sample-and-hold)
                  default is a regular line
+H "words"     - headline. Default is derived from input file name.
                  With EMPTY as the only word, no headline is plotted.
                  With +LEG the headline goes into the legend.
 +H NOFEED      -
With +LEG : If a curve must be composed of a number of tslg calls
                  (e.g. plotting error bars, symbols and lines), the legend position
                  is not incremented and no text is added. Only the specimen is placed.

+LEG ["a-opts"]::["p-opts"] - prepare a legend. A legend item is added.
                  Without +keep the legend is drawn using the p-opts
      a-opts    - Options for addlegend: lines, symbols, colors, text rendering...
-L- Options for pslegend: legend rendering, position, size...

If you need to add a curve manually and its legend entry, look here ("Additional legend entry")
+M "words"   -L- a subtitle. Enclose more than one word within " "
                  With EMPTY as the only word, no subtitle is plotted.
                  With +LEG the subtitle will be written as the main title. This is the
                  last action before the plot is closed.
                  Without +LEG the subtitle will be written
in 14-pt font size
                  and placed centered inside the diagram near the top.

A suggestion: Rely first on axes defaults before you try and tailor them with
and +TAX . The Calendar option isn't easy to handle either.

+T title    
-F- time-axis label. Default = "Year". Shorthands exist, see below.
                  title may consist of more than one word. Everything is taken as
                  title text until a leading `+´ is encountered. A lone + will
                  be necessary before a coming `-´ option.
                  Since colons cause interference with the GMT title delimiter,
                  use the octal code \072 instead.

                  Example: +T "s from 03\07200\07200" +  yields  [s] from 03:00:00
                  Since brackets cause difficulties inside the script,
                  enclose a unit in double slashes. For example,
                  +T Length //m// +  will be translated to  Length [m]
+TAX "opts-F- time-axis options for axlim4ts in addition to  -RB -pf10.3
 +TAX F rlo/rhi ticks
-F- "forced" = user-supplied parameters for GMT psxy -Rrlo/rhi and -Bticks
 +C title     -L- add calendar, month names, monthly divides, and 10-day ticks.
                  Rules for title are the same as under +T
 +CF title
    -L- like +C, plus an alternating color background for each month.
 +CO "opts"  
-L- options for calaxis. Use  calaxis -h  for information. 
 +Y title       - ordinate label. Default = "Signal". Shorthands exist, see below.
                  Rules for title are the same as under +T
+YAX "opt"     - ordinate options for axlim4ts in addition to  -RB -pf10.3

rlo/rhi ticks
                - "forced" = user-supplied parameters for GMT psxy -R../rlo/rhi and -B../ticks
 +YAX F0        - include zero in the axis range.

+P psfile    -F- PS output (PNG too), default is derived from input file name and label:
                  `basename file.ts`.ps  or  `basename file.ts`
 +A word      -F- to add a word at the end of the PS-file name (before the last `.´

+cc            - "continuous curve", removes the -m option in psxy.

 +tn [tfile
-L- Make (i.e. renew) a html page with a thumbnail collection;
                  requirement: PNGOUT has been set, and an html-template 
tfile (default: /home/hgs/TD/tslg-collection_html.template) exists
                  (~/bin/make-img-index-html is used)
 +EMPH color    - very special, apply together with -S : Plot the abs-max point filled in red
                  (cannot change the outline colour and stroke).
                 You probably need -m for coping with gaps. That's a default.
                 If that's a problem, use option +cc (continuous curve)
 -W3/0         - the default.

 TIME AXIS, first element of string:
  y | j | any   ->  [Years] | [MJD] | [any]
                The default will yield  Time [-]

 second element of string:
  @             -> "on date" where date is derived from input file
  g | a | p     -> "Gravity [nm/s@+2@+]" | "Acceleration [nm/s@+2@+]" | "Pressure [hPa]"
          Shorthands can be extended; edit the script at "# Shorthands:"
          or write a csh source script with definitions.  The variables are called
          tunits and yunits.

 PNGOUT        - the directory where to put the final PNG-file. Defaults to PNG/
                 or plot/PNG or plot/ or ./
 PNGRSL        - the resolution of the final PNG plot. Default = 144x144
 TSLG_FRAME    - the size of the diagram, default = -JX9/5
 TSLG_XORIGIN  - the horizontal distance between the left paper edge and
                 the diagram's origo. Default 1.5
TSLG_YORIGIN  - the vertical distance between the lower paper edge and
                 the diagram's origo. Default = psbasemap's default.
TSLG_LEGFEED  - 1 or -1 for legend entries going up or down. Default is 1, up.

          If a file
          exists, it will be sourced.

          The PS file name is stored in
          for re-use with
+cont or +right
          A little csh source script for parameter setting is saved / loaded:



        - output only, maybe useful for interspersing GMT commands
          Contains axes ranges and projection/diagram size


 setenv PNGOUT ~/www/4me/tslg/
 tslg d/ -L'B|V' -BHc2012,5,1 -U2012,7,1 +T Year +Y "Air pressure [hPa]" \
      -m -Sc0.03 -W1/0 -G0
           Note: In this example, tslist's default time format is used, float years.
           With -N time tags, the calendar option will not function.
           RJD and floating-point years are possible with +C

 tslg d/ -L'G|B' -E`pwd`/deci.tse,D10 -N -n/360 -D \
      -BHc2013,11,25,6 -U2013,11,25,7,20 -D \
      +T "Hours on 2013-11-25" +Y "Gravity [nm/s@+2@+]" \

      +P \
      +M "USGS: 2013-11-25 06:27:33 (M7.0) SOUTH ATLANTIC OCEAN -53.9 -54.9 (43a6c)"
 tslg d/ -L'G|B' -N -n/3600 +
           A bare minimum. We specify -N -n/3600 in order to get labels and ticks in units of hours (incl. an offset from midnight)..
           A single-component file spanning more than a year would cope with
 tslg file.ts +
  A particularly nice example is in Ttide/SCG/prl-files-and-coeffs

Another nice one in  TD/cal1504/calplot 
       calplot +P +O -ph

 A quick-view into a multi-year MC-file, plotting all components:
  foreach label ( `tslql -L,` )
    tslg $label +
    For shorter and much shorter files you'll need some ascii output options of tslist

Drawing tilt control curves:
  setenv PNGOUT $pngout
  tslg d/ -LTX -E`pwd`/tiltclean.tse,C \
       +keep +T y +LEG -W8/0/0/255:: +P +H TX-Power -W3/0/0/255
  tslg d/ -LTY -E`pwd`/tiltclean.tse,C \
       +cont +LEG -W8/255/0/::-JX2/0.5 +H TY-Power \
       +M "Tilt control up to "`tslqd e -: d/` -W3/255/0/0
from ~/TD/tilt-control-monitor . With legend.
  Additional legend entry:
cd plot/
source .tslg
plot your curve, e.g. with                      psxy -R$tax[1]/$yax[1] -JX -K -O -W3/128 >> PS/ps-file
you can obtain the ps-file name with                eval `head -1`
set yleg=`echo "SCG resid" | addlegend -y$yleg -d1 -W7/128`
echo set yleg = $yleg >> .tslg
cd ../
  or simpler with the special script  ~/bin/tslg-addlegend
cd plot/
source .tslg
set ps=`tslg-addlegend "SCG resid [@~m@~Gal]" -W3/128`
psxy ... >> PS/$ps
cd ../
