I am unable to understand how the plt.bar() function actually works.
Take the following code for example:
from collections import Counter
grades = [83, 95, 91, 87, 70, 0, 85, 82, 100, 67, 73, 77, 0]
# Bucket grades by decile, but put 100 in with the 90s
histogram = Counter(min(grade // 10 * 10, 90) for grade in grades)
plt.bar([x + 5 for x in histogram.keys()], # Shift bars right by 5
histogram.values(), # Give each bar its correct height
10, # Give each bar a width of 10
edgecolor=(0, 0, 0)) # Black edges for each bar
What does it mean by shift bars by 5 in the plt.bar() call? Does it mean by 5 pixels? 5%? 5% of what?
These measurements make no sense. Can someone explain to me how this works?

Five of the same units of your x-axis, which in this case, is points on someone’s grade.
