** plot Linear plot. **

plot(X,Y) plots vector Y versus vector X. If X or Y is a matrix,

then the vector is plotted versus the rows or columns of the matrix,

whichever line up. If X is a scalar and Y is a vector, length(Y)

disconnected points are plotted.

plot(Y) plots the columns of Y versus their index.

If Y is complex, plot(Y) is equivalent to plot(real(Y),imag(Y)).

In all other uses of PLOT, the imaginary part is ignored.

Various line types, plot symbols and colors may be obtained with

plot(X,Y,S) where S is a character string made from one element

from any or all the following 3 columns:

y yellow . point – solid

m magenta o circle : dotted

c cyan x x-mark -. dashdot

r red + plus — dashed

g green * star

b blue s square

w white d diamond

k black v triangle (down)

^ triangle (up)

< triangle (left) > triangle (right)

p pentagram

h hexagram

For example, plot(X,Y,’c+:’) plots a cyan dotted line with a plus

at each data point; plot(X,Y,’bd’) plots blue diamond at each data

point but does not draw any line.

plot(X1,Y1,S1,X2,Y2,S2,X3,Y3,S3,…) combines the plots defined by

the (X,Y,S) triples, where the X’s and Y’s are vectors or matrices

and the S’s are strings.

For example, plot(X,Y,’y-‘,X,Y,’go’) plots the data twice, with a

solid yellow line interpolating green circles at the data points.

The plot command, if no color is specified, makes automatic use of

the colors specified by the axes ColorOrder property. The default

ColorOrder is listed in the table above for color systems where the

default is yellow for one line, and for multiple lines, to cycle

through the first six colors in the table. For monochrome systems,

plot cycles over the axes LineStyleOrder property.

plot returns a column vector of handles to LINE objects, one

handle per line.

The X,Y pairs, or X,Y,S triples, can be followed by

parameter/value pairs to specify additional properties

of the lines.
