在 python 中用 seaborn 绘制条形 plot

Question

The data frame I am using: https://www.kaggle.com/mustiztemiz/diabetes

I have the following column:
Outcome - which has values 0 or 1.

I want to plot a barplot which has Outcome on the x-axis and the it's count on y-axis.

My code is as follows:

sns.barplot(x='Outcome', y=diabetes['Outcome'].value_counts(), data=diabetes)

It is returning the following plot

The output I got is wrong as 1 should be 268 in count and 0 should be 500 in count. I don't know where I did the mistake.

Answer 1

# encoding: utf-8

import pandas
import matplotlib.pyplot as plt
import seaborn as sns

diabetes = pandas.read_csv('diabetes.csv')


# solution one:
data = diabetes['Outcome'].value_counts()
sns.barplot(data.index, data.values)

# solution two:
sns.countplot(x='Outcome', data=diabetes)
