如何在 seaborn 栏中绘制数据框？

Question

I have a problem about drawing a seaborn bar plot in terms of this dataframe shown below

I created df_total shown below

df_total = df[['Confirmed','Recovered','Deaths']].sum()
df_total = df_total.reset_index()

Here is my dataframe named for df_total

index   0

0   Confirmed   145193

1   Recovered   70251

2   Deaths  5404

Plot

sns.barplot(x = "", y = ""
            data = df_total )

Which x and y values should be determined to draw bar plot?

Answer 1

Use DataFrame.rename_axis for set index name and then add parameter name in Series.reset_index :

df_total = df[['Confirmed','Recovered','Deaths']].sum()
df_total = df_total.rename_axis('a').reset_index(name='b')

sns.barplot(x = "a", y = 'b', data = df_total )

Your solution should be changed:

sns.barplot(x = "index", y = 0, data = df_total)
