Example categorical bar plot

import matplotlib.pyplot as plt
from statistics import mean


def chunks(l, n=2):
    """Yield successive n-sized chunks from l."""
    for i in range(0, len(l), n):
        yield l[i:i + n]


# Data to plot
result = [63, 1, 69, 29, 48, 56, 64, 16, 19, 51]
temperature = [4, 25, 37, 55, 70]

# Calculate mean of 2 samples
data = {
    str(temp): mean(result)
    for temp, result in zip(temperature, chunks(result))
}

plt.bar(data.keys(), data.values())
plt.show()
