Komplot function plotting (fortran only)
Function plotting, only in fortran
Subroutine functions with one parameter can be visualized by the routines in this section. DLAB, NP, XFROM, XTO, FX are common parameters.
DLAB (string) is a data label
NP is the number of equidistant X-coordinates from XFROM to XTO, the increase per coordinate = (XTO-XFROM)/(NP-1), NP>= 2.
FX is a real function subroutine of one REAL variable, used to compute the Y-coordinates belonging to the NP X-coordinates. Must be declared:
subroutine F_POLYLINE(DLAB, NP, XFROM, XTO, FX)
- Points connected as polyline, NP>=2.
subroutine F_DISJOINT_LINE(DLAB, NP, XFROM, XTO, FX)
- Points connected as disjoint line, NP>=2.
subroutine F_CURVE(DLAB, NP, XFROM, XTO, FX)
- Points connected by smooth interpolated line, NP>=3.
subroutine F_SPLINE(DLAB, NP, XFROM, XTO, FX))
subroutine F_MARKERS(DLAB, NP, XFROM, XTO, FX, ISYM)
- Points marked by symbol defined by ISYM
program yxx c make graph of y = x*x from 0.0 ... 10.0 EXTERNAL FX REAL XFROM, XTO XFROM = 0.0 XTO = 10.0 call FRAME (10., XFROM, XTO,8., 0., 0., 'X', 'Y', 'Function') call F_CURVE (21, XFROM, XTO, FX, 'y = x*x') end function FX(x) FX = x*x end
