-
ACTION = _CHAR (Read)
-
The type of function to be plotted. This must be one of the
following:
- "FUNC" - Use a Fortran-like expression to define the
function.
- "POLY" - Use a set of polynomial coefficients to define
the function.
- "SPLINE" - Use a set of spline coefficients from the file
SPLINEFILE to define the function.
[The value is prompted for.]
-
EXPRESSION = _CHAR (Read)
-
The Fortran-like expression to be plotted, in terms of X.
[The value is prompted for.]
-
XMIN = _REAL (Read)
-
The value of X from which the function is plotted.
[The value of the global parameter PONGO_XMIN is used.]
-
XMAX = _REAL (Read)
-
The value of X to which the function is plotted.
[The value of the global parameter PONGO_XMAX is used.]
-
INFILE = _LOGICAL (Read)
-
Used when ACTION is "POLY". If TRUE then the polynomial
coefficients are stored in a file (the first line of which is
the order of the polynomial), otherwise the coefficients
are given using the POLYCOEF parameter.
[FALSE]
-
NPOLY = _INTEGER (Read and Write)
-
The order of the polynomial: used when ACTION is "POLY".
[The value of the global parameter PONGO_NPOLY is used.]
-
POLYCOEF = _DOUBLE (Read)
-
A list of polynomial coefficients: used when ACTION is "POLY".
[The value of the global parameter PONGO_POLYCOEF is used.]
-
POLYFILE = _CHAR (Read)
-
The name of a file containing the polynomial coefficients to
be plotted. Only used when ACTION is "POLY" and INFILE is
TRUE.
[POLYFILE.dat]
-
SPLINEFILE = FILENAME (Read)
-
The name of the file containing the coefficients and knot
positions from a previous spline fit - used when ACTION is
"SPLINE".
[The value of the global parameter PONGO_SPLINEF is used. If
PONGO_SPLINEF is not defined, the value is prompted for.]
