Figure and axes creation in Data Analysis Python - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a figure in data visualization?

A figure is the entire window or page that holds one or more plots or charts. Think of it as a blank canvas where you draw your graphs.

beginner

What is an axes in a figure?

Axes are the parts of the figure where the actual data is plotted. It includes the x-axis, y-axis, and the area where the graph appears.

beginner

How do you create a figure and axes using Matplotlib in Python?

Use the command fig, ax = plt.subplots(). This creates a figure and a single axes inside it, ready for plotting.

intermediate

Why might you want to create multiple axes in one figure?

To show multiple plots side by side or in a grid, making it easier to compare data visually in one window.

beginner

What does the figsize parameter control when creating a figure?

It sets the size of the figure in inches, controlling how big or small the whole plot area will be.

Which command creates a figure and axes in Matplotlib?

A fig, ax = plt.subplots()

B plt.create_figure()

C axes = plt.figure()

D plot.figure()

The correct command is fig, ax = plt.subplots() which creates both figure and axes.

What does an axes object represent?

A The entire plotting window

B The area where data is plotted including axes lines

C Only the x-axis line

D The title of the plot

Axes is the area inside the figure where the data is drawn, including x and y axes.

How can you create multiple plots in one figure?

A By calling plt.plot() multiple times

B By using plt.figure() multiple times

C By creating multiple axes using plt.subplots() with rows and columns

D By changing the figure size

Using plt.subplots(nrows, ncols) creates multiple axes in one figure.

What does the figsize parameter control?

A The size of the figure in inches

B The number of axes

C The font size of labels

D The color of the plot

Figsize sets the width and height of the figure in inches.

If you want a single plot, which is the simplest way to create figure and axes?

A plt.axes() only

B plt.figure() only

C plt.plot() only

D fig, ax = plt.subplots()

Using plt.subplots() creates both figure and axes in one step.

Explain the difference between a figure and axes in data visualization.

Think of a figure as a page and axes as the drawing area on that page.

Describe how to create multiple plots in one figure using Python's Matplotlib.

Consider how you might arrange photos in a photo album.
