C Appendix: The Plot symbols

See Fig. 4!

0:
Nothing plotted
1:
Cross
2:
Asterisk
3:
Triangle, upright (llable)
4:
Square, axis-parallel (llable)
5:
Polygon (SIZE is redundant; if negative, the encircled area is lled)
6:
Cubic Spline Interpolation, solid line (also works for non-injective mappings). SIZE gives the spacing of the interpolated points in cm; negative SIZE: ll the encircled area).
7:
Cubic Spline Interpolation, dashed (also works for non-injective mapping). SIZE species both, the spacing of the interpolated points and the length of the dashes (in mm).
8:
Circle, negative SIZE lls the symbol. The diameter is 2=3SIZE and ts harmonically to the size of the other discrete symbols.
9:
Polygon, dashed (SIZE species the length of the dashes)
10:
Polygons, dash-dotted (SIZE species the length of the dashes)
11:
Triangle, upside-down (llable)
12:
Square, standing on corner (llable)
13:
Bomb (llable) - do not abuse !
14:
Star with three spikes (similar to the Daimler-Benz star) (llable)
15:
Rhomb (diamond, lozenge) (llable)
16:
Vertical dash, centered, SIZE species the length
17:
Rhomb (like SYMBOL=15), but lying (llable)
18:
Star with ve spikes (llable)
19:
Cubic Spline with sinusoidal modulation; SIZE regulates the amplitude and wavelength of the sine (i.e., they cannot be chosen independently)
20:
Polygons, dashed, gaps of double length (SIZE is the length of the dashes in cm)
21:
String of beads with crosses (SYMBOL 1). SIZE sets both their distance and size
22:
String of beads with asterisks (SYMBOL 2). SIZE sets both their distance and size
23:
String of beads with triangles (SYMBOL 3). SIZE sets both their distance and size, negative SIZE lls the symbols
24:
String of beads with squares (SYMBOL 4). SIZE sets both their distance and size, negative SIZE lls the symbols
25:
String of beads with triangles of their tip (SYMBOL 11). SIZE sets both their distance and size, negative SIZE lls the symbols
26:
Cross (llable)
27:
St Andrew's cross (llable)
28:
String of beads with circles (SYMBOL 8). SIZE sets both their distance and size, negative SIZE lls the symbols
31:
String of beads with triangles of their tip (SYMBOL 11). SIZE sets both their distance and size, negative SIZE lls the symbols { (redundant to SYMBOL 25).
32:
String of beads with squares of their tip (SYMBOL 12). SIZE sets both their distance and size, negative SIZE lls the symbols
35:
Histogram, solid lines; negative SIZE lls the area underneath
36:
Histogram, dashed, negative SIZE lls the area underneath
40:
False color representation. The y values of the dataset are encoded in false colors (COLOR 1{5, see Fig.  4) and plotted in an horizontal strip (cf. COMMAND STRIP for details).

By default, the color table is scaled to the minimum and maximum of the dataset, unless specied otherwise: WRplot has global variables MIN_COL and MAX_COL that inuence the part taken from the color table (so they need to be specied in the INSTRUCTION-EXPORT block, see page 90).

The color table is scaled to the minimum and maximum of the dataset by default unless specied otherwise: However, the user can dene the variables MIN_COL and MAX_COL (within an INSTRUCTION EXPORT block) in order to x these values globally, as shown in the following example:

nINSTRUCTION EXPORT
nVAR MIN_COL = 123.4
nVAR MAX_COL = 5000
nINSTRUCTION NO-EXPORT

Eect: the color table starts at y = 123:4 and ends at y = 5000. y-values smaller then MIN_COL are coded with the color of MIN_COL, while y-values larger then MAX_COL are coded with the color of MAX_COL,

Figure 5: The available symbols for plotting, llable discrete symbols are painted red (ll with a negative SIZE value). Note: Symbols 5 to 7, and 35+36 show the same dataset in this example.
