The style option in the plot command is a character string that consists of 1, 2 or 3 characters that specify the
color and/or the line style. The different color, line-style and marker-style options are summarized in Table 1.28.

Table 1.28 Color, line-style and marker-style options
Color style-option Line style-option Marker style-option
y yellow – solid + plus sign
m magenta – – dashed o circle
c cyan : dotted * asterisk
r red – . dash-dot x x-mark
g green . point
b blue ^ up triangle
w white s square
k black d diamond, etc.

1.17.2 Specialized 2-D Plots
There are several specialized graphics functions available in MATLAB for 2-D plots. The list of functions
commonly used in MATLAB for plotting x-y data are given in Table 1.29.
