可以按这个顺序来输入线形命令：

线形
-    Solid line (default)
--   Dashed line
:     Dotted line
-.   Dash-dot line

颜色
r  Red
g  Green
b   Blue
c   Cyan
m  Magenta
y  Yellow
k   Black
w  White

数据点的形状
+  Plus sign
o  Circle
*  Asterisk
.  Point 
x    Cross
'square' or s    Square 
'diamond' or d    Diamond
^  Upward-pointing triangle
v   Downward-pointing triangle
>  Right-pointing triangle

'pentagram' or p    Five-pointed star (pentagram)
'hexagram' or h     Six-pointed star (hexagram)

Examples

Plot the sine function over three different ranges using different line styles, colors, and markers. 
t = 0:pi/20:2*pi;
plot(t,sin(t),'-.r*')
hold on
plot(t,sin(t-pi/2),'--mo')
plot(t,sin(t-pi),':bs')
hold off

RGB Value	Short Name	Long Name
[1 1 0]	y	yellow
[1 0 1]	m	magenta
[0 1 1]	c	cyan
[1 0 0]	r	red
[0 1 0]	g	green
[0 0 1]	b	blue
[1 1 1]	w	white
[0 0 0]	k	black

使用形式：    line([Radius1*cos(angle1), Radius2*cos(angle2)],[Radius1*sin(angle1), Radius2*sin(angle2)], 'linewidth' ,2,'Color',[0 0 1])
