Subplot for multiple panels in MATLAB - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the subplot function do in MATLAB?

It divides the figure window into a grid of smaller axes (panels) and selects one for plotting.

How do you create a 2-by-3 grid of plots and select the 4th panel?

Use subplot(2, 3, 4). This means 2 rows, 3 columns, and the 4th panel is active.

What happens if you call subplot multiple times with the same position?

The new plot replaces the old one in that panel, clearing previous content.

beginner

How can you add a title to each subplot panel?

After calling subplot, use title('Your Title') to add a title to that panel.

How to create a 2x2 subplot and plot different data in each panel?

Call subplot(2,2,i) for i=1 to 4, then plot data in each selected panel separately.

What does subplot(3,1,2) do?

A Creates a grid with 3 rows, 1 column, and selects the 2nd panel

B Creates a grid with 1 row, 3 columns, and selects the 2nd panel

C Creates a grid with 3 rows, 1 column, and selects the 3rd panel

D Creates a grid with 2 rows, 3 columns, and selects the 1st panel

The first two numbers define rows and columns, the third is the panel number.

If you want 4 plots in one figure arranged in 2 rows and 2 columns, which command is correct to select the last panel?

A subplot(1,4,4)

B subplot(2,2,4)

C subplot(4,1,2)

D subplot(2,4,4)

2 rows and 2 columns means 4 panels; 4th panel is selected by subplot(2,2,4).

What happens if you plot twice on the same subplot without holding on?

A The second plot replaces the first

B Both plots appear together

C An error occurs

D The figure window closes

By default, new plots overwrite old plots in the same axes.

How do you add a title to a specific subplot?

A Use <code>figure</code> to add a title

B Use <code>subplot</code> with a title argument

C Call <code>title</code> after selecting the subplot

D Titles cannot be added to subplots

You select the subplot first, then call title('text').

Which command creates a 3x2 grid of subplots?

A subplot(1,6,1)

B subplot(2,3,1)

C subplot(6,1,1)

D subplot(3,2,1)

The first two numbers are rows and columns: 3 rows, 2 columns.

Explain how to create multiple panels in one figure using subplot in MATLAB.

Think of dividing a window into smaller boxes and drawing in each box.

Describe how to add titles and labels to individual subplot panels.

Each panel is like a mini-plot with its own decorations.
