HELP SECTION

PLOTR
Type: Task
Use:  PLOTR will write commands to a plot file for the execution
      of a ????? plot for an arbitrary data file.  Up to 30 types of
      data may be in the input text file, each of which may be plotted
      with a selected plot symbol (or omitted).  They may be connected
      by lines as well and may even be fit with ordinary or orthogonal
      polynomials.
Adverbs:
  USERID......The ID of the owner of the image.  Ignored
  INNAME......Image name (name).       Standard defaults.  The plot file
              is attached to this AIPS file which is otherwise ignored.
  INCLASS.....Image name (class).      Standard defaults.
  INSEQ.......Image name (seq. #).     0 => highest.
  INDISK......Disk unit #.             0 => any.
  INTEXT......Text file containing plot strings and plot data (see

  APARM.......(1,2) X plot range.  If APARM(2) <= APARM(1), self scale.
              (3,4) Y plot range.  If APARM(2) <= APARM(1), self scale.
                 These are after any scaling, functions in APARM
              Scale and apply function to X and Y values:
              On x axis plot function in APARM(7) of the value
                 APARM(5)*X+APARM(6)
              On y axis plot function in APARM(10) of the value
                 APARM(8)*Y+APARM(9)
              APARM(5)=0 => 1; APARM(8)=0 => 1
              Function types:
                 0  none (linear)
                 1  log

  RPARM.......(1-30) Plot symbol number for data of type 1-30, resp.
              You may have both a symbol and a line for each type
              0: No symbol plotted for this type
              1: Plus sign             12: Five pointed star
              2: Cross (X)             13: Star of David

                                       24: Cross (X) with gap
  VPARM.......(1-30) Line type number for data of type 1-30, resp.
              You may have both a symbol and a line for each type
              0: No line plotted for this type
              1: connected solid step line
              2: connected solid line
              3: dashed line, 1 break between points
              4: dashed line, 2 breaks between points
              5: and so on (VPARM(I)-2 breaks between points)
  FPARM.......(1-30) Optional polynomial fitting of curve of type 1-30
              If polynomial fit, the VPARM lines are the fit curve
              not lines between the data points.
              0: no fitting
              > 0, fit with ordinary polynomial of order FPARM(i).
                   The rms and parameters of the fit will be reported.
              < 0, fit with orthogonal polynomial of order
                   abs(FPARM(i)).  The rms of the fit will be reported
                   but the parameters are not very meaningful.
                   Maximum is 8 but the task may not be able to find
                   orthogonal polynomials this high, depending on the
                   input data.
  FACTOR......Symbol size multiplier; 0 -> 1.
  DOCOLOR.....> 0 => each symbol will be drawn with a color from blue
              to red as the color column value ranges from 0 to 1 or
              as line "types" 1,2,3,4 as the color column contains
              values 2,3,4,5 (resp).  Note that, by default, line type
              1 is used for labeling, line type 2 is used for
              connected lines, line type 3 for connected step lines,
              and line type 4 for symbols.
  LTYPE.......Labelling type, see HELP LTYPE for details:
              1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 =
              relative to ref. pixel, 5 or 9 = relative to subimage
              (BLC, TRC) center, 6 or 10 = pixels.  7-10 all labels
              other than tick numbers and axis type are omitted.
              Less than 0 is the same except that the plot file
              version number and create time are omitted.
              Add n * 100 to alter the metric scaling.
  DOTV........> 0 => plot directly on the TV device, otherwise
              make a plot file for later display on one or
              more devices (including the TV if desired).
  GRCHAN......Graphics channel (1 - 7) to use for line drawing.
              0 => 1.

PLOTR: Task to create a PLOTR-plot extension file
DOCUMENTOR:
RELATED PROGRAMS: TKPL, TVPL, LWPLA

                           PURPOSE

     PLOTR generates a plot extension file containing a PLOTR plot,
its border, and labels.  The plot itself may be displayed on a
printer, TEK screen, or TV graphics channel by the tasks PRTPL, TKPL,
or TVPL respectively.

                          COMMENTS

The INTEXT text file begins with 5 lines of text containing

   Line        Contents
     1      Plot title (at top of plot)
     2      Bottom line #1
     3      Bottom line #2
     4      X-axis label (<= 20 chars)
     5      Y-axis label (<= 20 chars)

Then, optionally, lines giving symbol labels for types -1 through -30
using format:
   SL n text
where SL starts in column 1 of the line, n is the label for symbol
types n (either sign will be interpreted as -1 through -30).  The text
of the label starts with the first non-blank after the number.

Then 1 line per data point for up to a total of 100000 points for 30
types giving X(i) Y(i) Type(i), where Type is an integer from 1
through 30.  Type 0 (or blank) -> type 1.  Negative types use the same
symbol as their positives but also plot the string given at the
beginning of the file.  Thus they are normally used for annotation is
some otherwise blank part of the plot.

At any point in the input file you may insert comment lines.  Any line
starting with $ or # is taken as a comment and ignored.
