What is the purpose of grid lines in a matplotlib plot?

Grid lines help to visually align data points with the axis values, making it easier to read and interpret the plot.

How do you enable grid lines on a matplotlib plot?

Use the plt.grid(True) function to turn on grid lines on the current plot.

Which parameter controls the line style of grid lines in matplotlib?

The linestyle parameter controls the style of grid lines, such as solid ('-'), dashed ('--'), or dotted (':').

intermediate

How can you customize the color and width of grid lines in matplotlib?

Use the color parameter to set the grid line color and linewidth to set the thickness, for example: plt.grid(color='red', linewidth=0.5).

What does the axis parameter do in the plt.grid() function?

The axis parameter specifies which axis to apply grid lines to: 'both' (default), 'x', or 'y'.

Which function enables grid lines in matplotlib?

A plt.showGrid()

B plt.grid(True)

C plt.enableGrid()

D plt.gridlines()

The correct function to enable grid lines is plt.grid(True).

How do you make grid lines dashed in matplotlib?

A plt.grid(line='dashed')

B plt.grid(style='dashed')

C plt.grid(dash=True)

D plt.grid(linestyle='--')

Use the linestyle='--' parameter inside plt.grid() to make dashed grid lines.

To show grid lines only on the y-axis, which parameter should you use?

A axis='x'

B axis='both'

C axis='y'

D axis='none'

Set axis='y' in plt.grid() to show grid lines only on the y-axis.

Which parameter changes the thickness of grid lines?

A linewidth

B thickness

C size

D weight

The linewidth parameter controls the thickness of grid lines.

What is the default axis setting for grid lines in matplotlib?

A both

B x

C y

D none

By default, grid lines are shown on both axes (axis='both').

Explain how to customize grid lines in a matplotlib plot including color, style, and width.

Think about the parameters inside plt.grid() that control appearance.

Describe how to enable grid lines only on the x-axis in matplotlib and why you might want to do this.

Consider how grid lines can help focus on one dimension.
