plotsym

Plot with symbols

Calling Sequence

plotsym(x,y,S)
plotsym(x,y,s,S,c,C,symsize)

Description

Plot with symbols Input S is one of the following

's'  square           
       'd'  diamond
       't'  triangle
'i'  inverted triangle
'l'  left triangle
'r'  right triangle
'c'  circle

In the longer call s is vector that contains category marker that is plotted with symbol from text string S, i.e element i is plotted with symbol S(s(i)), c is vector for colormarking, and C is corresponding string of 'rgbcymwk' in permuted order. If C is omitted then c is taken as a colour in itself. The colors may then be changed by calling colormap. The input symsize defines the symbol size relative to the default size which is 1. It may be a scalar, which is then applied to all symbols, or a vector, one for each symbol.

Examples:

plotsym(x,y,z,'st','rb')

Points x,y are plotted with red squares (z=1) or blue triangles (z=2).

plotsym(x,y,'s',z,2)

Points x,y are plotted with squares of twice the standard size, filled with colors according to value in z and current colormap.
