--   Dashed line

:     Dotted line

-.   Dash-dot line

颜色

'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
