Как упорядочить гистограммы, используя matplotlib в порядке возрастания чисел?

Question

Мне интересно, как выровнять гистограммы по оси X в порядке возрастания чисел в matplotlib. У меня есть 4 набора данных, которые представлены на гистограмме, но они сгруппированы в порядке, в котором я поместил их в свой сценарий. Есть ли способ разбить эту группировку и выровнять все столбцы в порядке возрастания?

Здесь приведен мой полный код, и я также разместил изображение, которое получаю, когда запускаю скрипт.

#usr/bin/env python3

import os
import xml.etree.ElementTree as ET  # Imports xml.etree.ElementTree which allows you to easily parse an XML file.import matplotlib.pyplot as plt
import matplotlib.pyplot as plt

concat_xml_dir = os.listdir(path_to_concat_xml_dir) #this contains XML files from multiple directories. The files have not been concatenated.

first_hit_hsp_e_value_list = []
second_hit_hsp_bit_score_list = []

third_hit_hsp_e_value_list = []
fourth_hit_hsp_bit_score_list = []
fourth_hit_hsp_e_value_list = []

for file in concat_xml_dir:
    #print(file)
    if file.endswith(".xml"):
        xml_file_path = os.path.join(path_to_concat_xml_dir, file)
        #print(xml_file_path)
        xml_files = open(xml_file_path, 'r')
        for lines in xml_files:
            #print(lines)
            tree = ET.parse(xml_files)  # ElementTree is now parsing all of the XML tblastn files.
            root = tree.getroot()  # This defines the root for each of the XML files. Since all the files have an identical format the root of each file is 'BlastOutput'.
