Plotting Multiple Data Sets in One Graph

Multiple x-y pair arguments create multiple graphs with a single call to plot.

MATLAB automatically cycles through a predefined (but user settable) list of

colors to allow discrimination among sets of data. See the axes

ColorOrder

and LineStyleOrder propertie s.

For example, these statements plot three related functions of

x,witheach

curve in a separate distinguishing color:

x = 0:pi/100:2*pi;

y = sin(x);

y2 = sin(x-.25);

y3 = sin(x-.5);

plot(x,y,x,y2,x,y3)

The legend command provides an easy way to identify the individual plots:
