DESCRIPTION

A symbol detail specification occupies one line in a script file, and contains one or more sub-attribute settings. A sub-attribute setting has the form subattribute=value with no embedded spaces. Multiple sub-attribute settings on the line are separated by white-space. Many of the keywords may be abbreviated to two or three characters.

EXAMPLES

symbols2

Here is the script that generated the above example:

#proc symbol
location: 1 1
symbol: style=outline fillcolor=blue linecolor=red radius=0.1

#proc symbol
location: 2 1
symbol: style=outline fillcolor=blue radius=0.1

#proc symbol
location: 3 1
symbol: style=fill fillcolor=blue radius=0.1

#proc symbol
location: 4 1
symbol: style=outline linecolor=red radius=0.1

#proc symbol
location: 5 1
symbol: style=spokes linecolor=green radius=0.1

A Gallery example that uses symbol details specifications (symbol:) is scatterplot1

SUB-ATTRIBUTES

shape=s

where s may be one of: triangle, downtriangle, diamond, square, pentagon, circle, lefttriangle, righttriangle, nicecircle. A triangle points up; a downtriangle points down, etc. A circle has 12 points; a nicecircle has 20.

style=s

where s may be one of: outline (draw outline; fill if fillcolor specified), spokes (draw spokes), and fill (fill with color but don't draw outline).

radius=r

where r is the radius of the symbol in absolute units

fillcolor= color

the color to use for filling in the symbol.

linecolor= color

the color to use for the lines of the symbol.

linewidth=linewidth

the linewidth to use for the lines of the symbol. See linedetails

imgfile=name

the name of an image file to use as the symbol. Image file format must be the same as the ploticus result. Formerly called pngfile.

imgscale=sx[,sy]

scale factor to apply to symbol imgfile. If only sx is given, equal amount of scaling is applied in both X and Y directions. Otherwise sx is the scale factor in X, and sy the scale factor in Y. A scale factor of 1.0 uses the original size; a smaller value shrinks the image; a larger value enlarges it. Formerly called pngscale.

symcode

a graphcore symcode may be specified directly if desired. This is a compact specification for selecting a geometric symbol for marking data points. The symbol code is a string representation of the form: symNS[C], where N is an integer 1-8 selecting the shape: (1=triangle pointing up; 2=triangle pointing down; 3=diamond; 4=square; 5=pentagon; 6=circle; 7=triangle pointing left; 8=triangle pointing right). S is either 's' for spokes, 'a' for outline, or 'n' for no outline. C is a fill color which may be different from current line color (if omitted, no filling takes place).

Here is an example:
