What symbol is used for a solid line style in MATLAB plots?

The solid line style is represented by a single dash: '-'.

beginner

How do you specify a red color for a plot line in MATLAB?

Use the character 'r' to specify red color in the plot command.

beginner

Name three marker symbols you can use in MATLAB plots.

Common markers include: 'o' (circle), '*' (star), and 's' (square).

intermediate

How do you combine line style, marker, and color in one plot command?

You combine them as a string, for example: '-or' means solid line -, circle marker o, and red color r.

beginner

What is the default line style and marker if none is specified in MATLAB plot?

The default is a solid line '-' with no markers.

Which of these is the correct way to plot a blue dashed line with square markers in MATLAB?

A plot(x, y, '--bs')

B plot(x, y, '-ro')

C plot(x, y, ':g*')

D plot(x, y, '-.k^')

Option A uses '--' for dashed line, 'b' for blue color, and 's' for square markers.

What marker symbol represents a star in MATLAB plots?

A o

B *

C s

D d

The star marker is represented by '*'.

How do you specify a green dotted line in MATLAB?

A '--g'

B '-g'

C ':g'

D '-.g'

If you want no markers but a red dash-dot line, which style string do you use?

A '-.r'

B '-r'

C '--r'

Explain how to create a plot line in MATLAB with a green dashed line, circle markers, and no fill color.

Remember the order of line style, marker, and color can be combined in one string.

List and describe the basic line styles and marker symbols available in MATLAB plotting.

Think about common shapes and line patterns you see in graphs.
