3 Graphics

• Line style strings are '-' for solid, '--' for dashed, ':' for dotted, and

'-.' for dash-dot. Omit the line style for no line.

• The marker types are

'+', 'o', '*',and'x', and the filled marker types

are

's' for squar e, 'd' for diamond, '^ ' for up tria ng le, 'v' for down

triangle,

'>' for right triangle, '< ' for left triangle, 'p' for pentagram, 'h'

for hexagram, and none for no marker.

You can also edit color, line style, and markers interactively. See “E diting

Plots” on pag e 3-17 for more information.

Plotting Lines and Markers

If you specify a marker type but not a line style, MATLAB draws only the

marker. For example,

plot(x,y,'ks')

plots black squares a t each data point, but does not connect the markers

with a line.

The statement

plot(x,y,'r:+')

plots a red dotted line and places plus sign markers at each data point.

Placing Markers at Every Tenth Data Point

You might want to use fewer data points to plot the markers than you use to

plot the lines. This example plots the data twice using a different number of

points for the dotted line and marker plots:

x1 = 0:pi/100:2*pi;

x2 = 0:pi/10:2*pi;

plot(x1,sin(x1),'r:',x2,sin(x2),'r +')
