plt.boxplot()

plt.boxplot() 是 Matplotlib 库中的一个函数，用于绘制箱线图。箱线图是一种用于展示数据分布情况的统计图表，它展示了一组数据的中位数、四分位数、最大值和最小值等统计量。箱线图常用于发现数据集中的异常值、比较不同数据集之间的差异等。

该函数可以接受一个或多个数据集作为输入，每个数据集可以是一个列表、数组或者 Series 对象。使用不同的输入数据集，可以绘制出多个箱线图并进行比较。

示例用法如下：

import matplotlib.pyplot as plt

data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
plt.boxplot(data)

plt.show()

上述代码会绘制一个简单的箱线图，显示出数据集的中位数、上下四分位数、最大值和最小值。你可以根据自己的数据和需求进行相应的调整和定制。

plt.boxplot

The `plt.boxplot()` function is a method in the Matplotlib library used to create box plots, also known as box-and-whisker plots. Box plots are used to show the distribution of a dataset by displaying the median, quartiles, and outliers of the data.

The function takes in a list of data values as its primary input and returns a box plot. Additional parameters can be used to customize the appearance of the plot, such as changing the color, width, and style of the boxes and whiskers.

Here is an example of using `plt.boxplot()` function to create a box plot for a dataset:

import matplotlib.pyplot as plt
import numpy as np

# create a dataset
data = [np.random.normal(0, std, 100) for std in range(1, 4)]

# create a box plot
plt.boxplot(data)

# add labels and title
plt.xticks([1, 2, 3], ['Data 1', 'Data 2', 'Data 3'])
plt.ylabel('Value')
plt.title('Box plot example')

# display the plot
plt.show()

This code will generate a box plot that shows the distribution of three datasets with different standard deviations. The x-axis labels indicate which dataset each box represents, and the y-axis shows the values of the data. The box represents the interquartile range (IQR), which is the middle 50% of the data, and the whiskers extend to the minimum and maximum values within 1.5 times the IQR. Any values outside of this range are considered outliers and are plotted as individual points.

plt.boxplot缺失值

plt.boxplot函数在处理缺失值时的默认行为是忽略缺失值并正常绘制箱线图。即使数据中存在缺失值，plt.boxplot函数仍会绘制出箱线图。 如果你想在箱线图中显示缺失值，你可以先通过pandas库或其他方法对数据进行处理，将缺失值替换为特定的数值，然后再传递给plt.boxplot函数进行绘制。
