DASHDC - Defines a dash pattern with labels. If DASHDC is called when the "quick" version of Dashline is used, an error exit results.
CALL DASHDC (IPAT,JCRT,JSIZE)
void c_dashdc (char *ipat, int jcrt, int jsize)
- (an input constant or variable of type CHARACTER) specifies the dash pattern to be used. Although IPAT is of arbitrary length, 60 characters seems to be a practical limit. This pattern is repeated for successive line segments until the full line is drawn. A dollar sign in IPAT indicates solid; an apostrophe indicates a gap; blanks are ignored. Any character in IPAT which is not a dollar sign, apostrophe, or blank is considered to be part of a line label. Each line label can be at most 15 characters in length. Sufficient white space is reserved in the dashed line for writing line labels.
- (an input expression of type INTEGER) specifies that the length to be assigned to each increment of the line pattern is (JCRT/1023.) NDCs (Normalized Device Coordinates). Each increment is either a gap (represented by a dollar sign in IPAT) or a line segment (represented by an apostrophe in IPAT). JCRT must be greater than or equal to 1.
- (an input expression of type INTEGER) specifies the width of the plotted characters, as follows:
- .0078 NDCs
- .0117 NDCs
- .0156 NDCs
- .0234 NDCs
- JSIZE/1023. NDCs
The C-binding argument descriptions are the same as the FORTRAN argument descriptions.
Use the ncargex command to see the following relevant examples: tdashc, tdashp, tdashs, fcoord1, fcoord2, fdldashc, fdldashd.
DASHDC may be called to define a dash pattern for any of the four versions of Dashline except the "quick" version; if you call it when the "quick" version is in use, an error exit will result.
A dash pattern defined by a call to DASHDC will supersede one defined by an earlier call to DASHDB or DASHDC.
To use DASHDC or c_dashdc, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
