Dashsupr – The dash utilities have all been incorporated into the Dashline utility. To see its man page, type "man dashline".
Dashsmth – The dash utilities have all been incorporated into the Dashline utility. To see its man page, type "man dashline".
Dashpack_params – This document briefly describes all Dashpack parameters. DescriptionDashpack has twenty internal parameters that affect what it does. The current value of a parameter may be retrieved by calling one of the routines DPGETC, DPGETI or DPGETR. A parameter may be given a new value by calling one of the routines DPSETC, DPSETI, or…
Dashpack – a set of routines allowing you to draw curves using dashed-line patterns that may include gap-portion specifiers, solid-portion specifiers, and label-string specifiers. DASHPACK is intended to replace and unify the old family of NCAR Graphics routines (DASHLINE, DASHCHAR, DASHSMTH, and DASHSUPR), all of which date from the early 1970s or before. At the…
Dashline_params – Brief descriptions of all internal parameters of Dashline. DescriptionNo parameter-access routines are available for the utility Dashline. Parameters are set through the common blocks SMFLAG, INTPR, and DASHD1. There are four different versions of Dashline: normal, quick, smooth, and super. Which version is used depends on options used on the ncargf77 command line….
Dashline – A set of line-drawing routines that can be used to generate various dashed line patterns (including solid), can add labels to the lines, can smooth the lines, and can suppress crowding of lines. There are four different versions of Dashline: "normal", "quick", "smooth", and "super". See the ACCESS Section for details on how…
DASHDC – Defines a dash pattern with labels. If DASHDC is called when the "quick" version of Dashline is used, an error exit results. SynopsisCALL DASHDC (IPAT,JCRT,JSIZE) C-Binding Synopsis#include <ncarg/ncargC.h> void c_dashdc (char *ipat, int jcrt, int jsize) DescriptionIPAT (an input constant or variable of type CHARACTER) specifies the dash pattern to be used. Although…
DASHDB – Defines a dash pattern without labels. SynopsisCALL DASHDB (IPAT) C-Binding Synopsis#include <ncarg/ncargC.h> void c_dashdb (int *ipat) DescriptionIPAT (an input expression of type INTEGER) is a 16-bit dash pattern (1=solid, 0=blank); e.g., the binary number 1111000011110000, which is a decimal 61680, will give dashes of medium length.C-Binding DescriptionThe C-binding argument description is the same…
Dashchar – The dash utilities have all been incorporated into the Dashline utility. To see its man page, type "man dashline".
DANDR – Draws an isosurface when used in conjunction with entry INIT3D. SynopsisCALL DANDR (NV,NW,ST1,LX,NX,NY,IS2,IU,S,IOBJS,MV) StatusThis routine is part of the obsolete Isosrfhr utility. Isosrfhr has been replaced by the Isosurface utility. To see the Isosurface utility overview man page, type "man isosurface". DescriptionNV (an input expression of type INTEGER) defines the range to be…
CURVS2 – calculates an interpolated value for a smoothing spline under tension at a given point. SynopsisFUNCTION CURVS2(T,N,PARAM,X,Y,XP,YP,SIGMA,XO,YO) This subroutine is a companion to CURV1S which must be called before calling this subroutine. CURV2S calculates an interpolated value for a smoothing spline under tension at a given point. DescriptionT (real, input) A real value to…
CURVS1 – calculate values for a smoothing spline for data in the plane. SynopsisCALL CURVS1 (N,X,Y,D,ISW,S,EPS,PARAM,XS,YS,XSP,YSP, SIGMA,TEMP,IERR) This subroutine calculates certain values that are used by CURVS2 in order to compute an interpolatory smoothing spline under tension through a sequence of data values in the plane. In general this curve will not pass through the…
CURVS – calculate values for a smoothing spline SynopsisCALL CURVS (N, X, Y, D, ISW, S, EPS, YS, YSP, SIGMA, TEMP, IER) This subroutine calculates certain values that are used by CURV2 in order to compute an interpolatory smoothing spline under tension through a sequence of functional values. The actual computation of the interpolated values…
