Explanation: plt.title() sets the overall title for the current plot.

10. Which function is used to add a legend to a plot?

a) plt.add_legend() b) plt.legend() c) plt.key() d) plt.show_legend()

Explanation: plt.legend() places a legend on the axes, which identifies labeled plot elements.

11. To save a chart as an image file (e.g., PNG or JPEG) directly from script, which method is used?

a) plt.save() b) plt.export() c) plt.savefig() d) plt.write()

Explanation: plt.savefig('filename.png') saves the current figure as a static image file.

12. What does the parameter 'linestyle' (or 'ls') in plt.plot() do?

a) Changes the thickness of line b) Changes the style of line (e.g. '--', ':') c) Changes marker color d) Adds grid lines

Explanation: linestyle/ls defines line appearance such as solid ('-'), dashed ('--'), dotted (':'), or dash-dot ('-.').

13. What parameter in plt.plot() is used to set marker symbol for data points?

a) symbol b) point c) marker d) icon

Explanation: The 'marker' parameter (e.g., 'o', 's', '^', '*') sets the shape of individual data points on line plots.

14. How can grid lines be enabled on a Pyplot chart?

a) plt.grid(True) b) plt.show_grid() c) plt.gridlines() d) plt.enable_grid()

Explanation: plt.grid(True) or plt.grid() turns on grid lines on the active plot.

15. Which function creates Horizontal Bar Charts in Pyplot?

a) plt.bar_h() b) plt.barh() c) plt.hbar() d) plt.bar(orientation='horizontal')

Explanation: plt.barh() draws horizontal bar plots where x-values become bar lengths along the horizontal direction.

16. Which parameter in plt.bar() sets the width of the vertical bars?

a) bar_width b) width c) size d) thickness

Explanation: The 'width' keyword argument in plt.bar() sets the width of each bar (default is usually 0.8).

17. What parameter controls the color of markers on a line plot?

a) markercolor b) markeredgecolor c) markerfacecolor (or mfc) d) fillcolor

Explanation: markerfacecolor (or mfc) sets the inner fill color of the plot marker.

18. Which statement correctly imports pyplot module under the alias name 'plt'?

a) import matplotlib as plt b) import pyplot as plt c) import matplotlib.pyplot as plt d) from matplotlib import pyplot

Explanation: Standard convention in Python data science is 'import matplotlib.pyplot as plt'.

19. What type of chart is ideal for showing continuous data distribution across intervals?

a) Bar Chart b) Line Chart c) Histogram d) Scatter Plot

Explanation: Histograms show continuous frequency distributions grouped into range bins.

20. In plt.hist(), what does the parameter 'edgecolor' specify?

a) Color of bar fill b) Color of the border lines of bins c) Plot background color d) Axis color

Explanation: edgecolor (or ec) sets the color of the outline/border around each histogram bin bar.

21. What happens if you call plt.plot([1, 2, 3, 4]) with only a single list?

a) It throws an error b) List is taken as X-values, Y defaults to 0 c) List is taken as Y-values, X defaults to [0, 1, 2, 3] d) No plot is created

Explanation: If a single sequence is provided to plt.plot(), Pyplot assumes it contains Y-values and automatically generates X-indices [0, 1, ..., N-1].

22. Which argument in plt.plot() specifies the size of markers?

a) markersize (or ms) b) size c) msize d) scale

Explanation: markersize or ms argument changes marker size in points.

23. How do you set custom limit ranges for X-axis in pyplot?

a) plt.xlimit(min, max) b) plt.xlim(min, max) c) plt.set_xlim(min, max) d) plt.range_x(min, max)

Explanation: 'loc' parameter specifies legend placement inside or outside the figure.

25. Which parameter in plt.barh() sets the vertical height of horizontal bars?

a) width b) height c) bar_size d) length

Explanation: In plt.barh(), bar thickness is controlled by 'height' (whereas in plt.bar() it is 'width').

26. Which value for 'kind' parameter is default when plotting directly from a Pandas DataFrame with df.plot()?

a) 'bar' b) 'hist' c) 'line' d) 'scatter'

Explanation: df.plot() defaults to creating a line plot unless specified otherwise via kind='...'.

27. In pyplot, what does plt.yticks() function do?

a) Draws horizontal grid b) Sets/Gets tick locations and labels on Y-axis c) Sets Y-axis title d) Changes Y-axis scale to log

Explanation: plt.yticks() specifies tick mark locations and label strings on Y-axis.

a) linewidth (or lw) b) thick c) borderwidth d) line_size

Explanation: linewidth or lw sets line width in points.

29. Why should plt.savefig() be called BEFORE plt.show() in Pyplot scripts?

a) plt.show() opens interactive window and clears the figure canvas b) plt.savefig() causes error after show() c) plt.show() deletes data d) Both can be called in any order

Explanation: plt.show() resets/clears the current figure upon closing, so saving after plt.show() often results in saving a blank image.

30. What parameter in plt.hist() creates cumulative frequency histogram?

a) frequency=True b) cumulative=True c) sum=True d) total=True

Explanation: When cumulative=True in plt.hist(), a histogram is drawn where each bin gives counts in that bin plus all smaller bins.
