如何在 pandas/matplotlib/seaborn 中绘制分类和连续数据

问题描述

我试图弄清楚如何绘制这些数据:

第1列['genre']:这些是表格中所有类型的值计数

剧情2453喜剧 2319行动1590恐怖915冒险 586惊悚491纪录片 432动画403犯罪 380幻想272科幻小说214浪漫 186家庭 144谜底 125音乐 100电视电影 78战争59历史 44西餐42国外9名称:流派，dtype:int64

第2栏['release_year']:这些是不同类型的所有发行年份的值计数

我需要回答类似的问题-哪种类型每年最流行?等等

可以使用什么样的图，因为在一个图表中会有很多箱，所以最好的方法是什么?

seaborn 是否更适合绘制此类变量?

我应该将年度数据划分为2个十年(1900年和2000年)吗?

解决方案

你可以这样做:

I am trying to figure out how could I plot this data:

1960     32
1969     31
1961     31
Name: release_year, dtype: int64

I need to answer the questions like - What genre is most popular from year to year? and so on

what kind of plots can be used and what is the best way to do this since there would be a lot of bins ins a single chart?

Is seaborn better for plotting such variables?

Should I divide the year data into 2 decades(1900 and 2000)?

Sample of the table:
    id   popularity runtime genres  vote_count  vote_average    release_year
0   135397  32.985763   124 Action     5562     6.5             2015

解决方案

You could do something like this:

Plotting histogram using seaborn for a dataframe

Personally i prefer seaborn for this kind of plots, because it's easier. But you can use matplotlib too.

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
import numpy as np

# sample data
samples = 300
ids = range(samples)
gind = np.random.randint(0, 4, samples)
years = np.random.randint(1990, 2000, samples)

# create sample dataframe
gkeys = {1: 'Drama', 2: 'Comedy', 3: 'Action', 4: 'Adventure', 0: 'Thriller'}
df = pd.DataFrame(zip(ids, gind, years),
                  columns=['ID', 'Genre', 'Year'])
df['Genre'] = df['Genre'].replace(gkeys)

# count the year groups
res = df.groupby(['Year', 'Genre']).count()
res = res.reset_index()

# only the max values
# res_ind = res.groupby(['Year']).idxmax()
# res = res.loc[res_ind['ID'].tolist()]

# viz
sns.set(style="white")
g = sns.catplot(x='Year',
                y= 'ID',
                hue='Genre',
                data=res,
                kind='bar',
                ci=None,
                   )
g.set_axis_labels("Year", "Count")
plt.show()

If this are to many bins in a plot, just split it up.
