📝 Note: This quiz contains 20 questions including multiple choice and multiple selection questions. Some questions may have more than one correct answer. Select all that apply for those questions.

1. Which function creates a new figure in Matplotlib?

plt.figure() plt.create() plt.new_figure() plt.plot()

2. What does plt.show() do?

Saves the figure to a file Displays the figure on screen Creates a new figure Closes all figures

3. Which functions add labels and titles to a plot? (Select all that apply)

plt.xlabel() plt.ylabel() plt.title() plt.label()

4. What type of plot is created with plt.scatter()?

Line plot Scatter plot Bar chart Histogram

5. Which function is used to create a histogram?

plt.bar() plt.hist() plt.histogram() plt.distribution()

6. What is the difference between plt.bar() and plt.barh()?

No difference, they're the same plt.bar() creates vertical bars, plt.barh() creates horizontal bars plt.bar() is for single series, plt.barh() is for multiple series plt.barh() is deprecated

7. Which function creates a box plot?

plt.box() plt.boxplot() plt.violin() plt.whisker()

8. What does the alpha parameter control in plotting functions?

Line width Transparency (0=fully transparent, 1=fully opaque) Marker size Color intensity

9. Which function is used to display 2D arrays as images or heatmaps?

plt.heatmap() plt.imshow() plt.image() plt.array()

10. What does plt.colorbar() add to a plot?

A color legend A color scale showing the mapping of values to colors A colored grid A color palette selector

11. How do you create multiple subplots in a single figure?

plt.multi_plot() plt.subplots() plt.panels() plt.grid()

12. What does ax.twinx() do?

Creates a mirror image of the plot Creates a second y-axis sharing the same x-axis Duplicates the current axes Inverts the x-axis

13. Which parameters are commonly used in plt.subplots()? (Select all that apply)

nrows (number of rows) ncols (number of columns) figsize (figure size) nplots (number of plots)

14. What does plt.tight_layout() do?

Compresses the figure vertically Automatically adjusts subplot parameters to prevent overlapping Removes all white space Makes lines thinner

15. Which file formats can Matplotlib save figures to? (Select all that apply)

PNG PDF SVG EPS

16. What parameter in plt.savefig() controls the resolution of the saved figure?

resolution dpi quality pixels

17. What does the extent parameter in plt.imshow() control?

The size of the figure The coordinate bounds of the image (left, right, bottom, top) The zoom level The color range

18. What is GridSpec used for?

Creating grid lines on plots Creating complex subplot layouts with varying sizes Specifying coordinate grids for data Setting grid spacing in plots

19. What does the bins parameter control in plt.hist()?

The height of bars The number or edges of bins for grouping data The width of the figure The color scheme

20. What is the purpose of plt.grid(True)?

Creates a subplot grid Adds grid lines to the plot for easier reading Aligns multiple plots Creates a data grid
