gradelib.plot.grade_distribution(gradebook: Gradebook, x_min: float = 0.6, x_max: float = 1, bin_width: float = 0.025)

Visualize the grade distribution with respect to a scale.

This will plot an interactive histogram of the grade distribution, with each individual grade marked as a dot. Furthermore, if a gradine scale is provided, the letter grade thresholds are marked on the histogram as vertical lines, and the frequency of each letter grade is shown.

Parameters:

  • gradebook (Gradebook)

  • x_min (float) – The smallest extent of the axis containing scores. Default: 0.6

  • x_max (float) – The greatest extent of the axis containing scores. Default: 1.02

  • bin_width – How wide each bin should be. Default: 0.025.
