如何增加条形图条形之间的间距

How do I increase the space between each bar with matplotlib barcharts, as they keep cramming them self to the centre. (this is what it currently looks)

import matplotlib.pyplot as plt
import matplotlib.dates as mdates
def ww(self):#wrongwords text file

    with open("wrongWords.txt") as file:
        array1 = []
        array2 = [] 
        for element in file:
            array1.append(element)

        x=array1[0]
    s = x.replace(')(', '),(') #removes the quote marks from csv file
    print(s)
    my_list = ast.literal_eval(s)
    print(my_list)
    my_dict = {}

    for item in my_list:
        my_dict[item[2]] = my_dict.get(item[2], 0) + 1

    plt.bar(range(len(my_dict)), my_dict.values(), align='center')
    plt.xticks(range(len(my_dict)), my_dict.keys())

    plt.show()

尝试更换

plt.bar(range(len(my_dict)), my_dict.values(), align='center')

with

plt.figure(figsize=(20, 3))  # width:20, height:3
plt.bar(range(len(my_dict)), my_dict.values(), align='edge', width=0.3)

选项align='edge'将消除条形图左侧的空白。

And width=0.3将条形的宽度设置为小于默认值。 条间距将相应调整。

对于沿 x 轴的标签，应将其旋转 90 度以使其可读。

plt.xticks(range(len(my_dict)), my_dict.keys(), rotation='vertical')
