What is the output of this matplotlib inline code?

Consider this code run in a Jupyter notebook cell:

import matplotlib.pyplot as plt
%matplotlib inline
plt.plot([1, 2, 3], [4, 5, 6])
plt.title('Simple Line Plot')
plt.show()

What will be displayed after running this cell?

Matplotlib

import matplotlib.pyplot as plt
%matplotlib inline
plt.plot([1, 2, 3], [4, 5, 6])
plt.title('Simple Line Plot')
plt.show()

A A static line plot image with points (1,4), (2,5), (3,6) and the title 'Simple Line Plot' shown below the code cell.

B An interactive plot window pops up outside the notebook showing the line plot.

C No plot is shown because plt.show() is missing.

D A blank output with no plot or title is displayed.

💡 Hint

Think about what %matplotlib inline does in Jupyter notebooks.

The magic command %matplotlib inline makes matplotlib plots appear as static images inside the notebook cells. The plt.show() call displays the plot inline with the title and data points.

Why use '%matplotlib inline' in Jupyter notebooks?

What is the main purpose of running the command %matplotlib inline in a Jupyter notebook?

A To save plots automatically to disk without displaying them.

B To enable interactive plot windows outside the notebook.

C To disable all matplotlib plotting in the notebook.

D To make matplotlib plots display as static images inside the notebook cells.

💡 Hint

Think about how plots appear by default in Jupyter notebooks.

The %matplotlib inline magic command configures matplotlib to show plots as static images embedded in the notebook output cells.

Why does this plot not display inline in Jupyter?

You run this code in a Jupyter notebook:

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.title('Test Plot')

No plot appears below the cell. What is the most likely reason?

Matplotlib

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.title('Test Plot')

A The magic command %matplotlib inline was not run, so plots do not display inline automatically.

B The plt.show() function is missing, so the plot is not rendered.

C The plot data is invalid, so nothing is drawn.

D The title function must be called before plot to display the title.

💡 Hint

Think about how matplotlib behaves in Jupyter without any magic commands.

Without %matplotlib inline, matplotlib plots do not automatically display inline in Jupyter notebooks. You must run that magic or call plt.show() explicitly.

❓ data_output

What is the output type when using inline matplotlib plots?

When you run matplotlib plotting commands with %matplotlib inline in a Jupyter notebook, what type of output is generated and displayed?

A A vector graphic file saved to disk automatically.

B A pop-up interactive window outside the notebook.

C A PNG image embedded as output below the code cell.

D A text description of the plot printed in the output.

💡 Hint

Think about how images appear inside notebook cells.

The inline backend converts matplotlib plots to PNG images embedded directly in the notebook output cells.

How to switch from inline to interactive matplotlib plots in Jupyter?

You want to switch from static inline matplotlib plots to interactive plots inside your Jupyter notebook. Which command should you run?

A %matplotlib inline

B %matplotlib notebook

C %matplotlib qt

D %matplotlib widget

💡 Hint

Think about which magic command enables interactive plots inside or outside the notebook.

The %matplotlib notebook magic enables interactive plots inside the notebook with zoom and pan. It switches from static inline images.
