矩阵条形图：空格条形图

Question

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()

Answer 1

这个答案会改变条形之间的间距，并且还会旋转 x 轴上的标签。它还允许您更改图形大小。

fig, ax = plt.subplots(figsize=(20,20))

# The first parameter would be the x value, 
# by editing the delta between the x-values 
# you change the space between bars
plt.bar([i*2 for i in range(100)], y_values)

# The first parameter is the same as above, 
# but the second parameter are the actual 
# texts you wanna display
plt.xticks([i*2 for i in range(100)], labels)

for tick in ax.get_xticklabels():
    tick.set_rotation(90)

Answer 2

有2种方法可以增加条之间的空间。这里参考的是绘图函数。

plt.bar(x, height, width=0.8, bottom=None, *, align='center', data=None, **kwargs)

plot函数有一个宽度参数，用于控制条形图的宽度。如果减小宽度，条间距将自动减小。默认情况下，您的宽度设置为0.8。

width = 0.5

如果您想保持宽度不变，您必须将条形图放在x轴上的位置隔开。您可以使用任何缩放参数。例如

x = (range(len(my_dict)))
new_x = [2*i for i in x]

# you might have to increase the size of the figure
plt.figure(figsize=(20, 3))  # width:10, height:8

plt.bar(new_x, my_dict.values(), align='center', width=0.8)

Answer 3

尝试替换

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

随着

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