status.i4.v = wn_symbol(x.r4.r, y.r4.r)
status.i4.v = wn_symbol_c(x.r4.v, y.r4.v)
This routine plots a symbol at specified real coordinates in a
graphics window specified by a previous call to wn_active(_c).
The symbol to be plotted is determined by the most recent call to
wn_set_plot_symbol(_c) or wn_setsym(_c). The available symbols
are: circle, square, triangle, cross, diamond, and any Lex Object.
All of the simple symbol types are available in either filled or
outline form depending on the current graphics fill mode.
x, y location of the symbol in real-world coordinates
This function returns ACNET status values as follows:
CBS_NOSETUP an active window has not been established
This function requires the following include files:
wn_symbol_set, wn_set_plot_symbol(_c), wn_setsym(_c), wn_color(_c),
wn_user_defined_color_c, wn_read_user_defined_color, wn_fill_mode(_c),
int type = WN_CIRCLE;
int size = 3;
float x = 1.0;
float y = 1.0;
status = wn_set_plot_symbol_c(type,size);
status = wn_symbol_c(x,y);
