Horizontal plot in swarmplot of seaborn

Question

Situation
I have the following pandas dataset:

|user_id|total|is_fat|
|-------|-----|------|
|1      |100  |1     |
|2      |150  |0     |
|3      |400  |1     |
|4      |500  |1     |
|5      |10   |0     |

where elements of the total are integer and elements of is_fat are string.

I denote above dataset by df.

Then run the following code:

import seaborn as sos
sns.swarmplot(x = 'total', y ='is_fat', data = df)

Now the graph I expected looks like:

Problem However, the output graph is the following:

Why?

If I convert '1' to 'fat' and '0' to 'not_fat', then I get the expected graph.

Try to check if `is_fat` is categorical before using it in the plot. — Lunalo John, Mar 12 '19 at 06:10
Thank you for your help! I try it and get a result what I want. — s_narisawa, Mar 13 '19 at 08:06

I have simulated some data and changed is_fat to categorical as shown:

import seaborn as sns
import pandas as pd
import numpy as np

df = pd.DataFrame({"total":abs(np.random.randn(100)), "is_fat": [1,0]*50})
df.is_fat = df.is_fat.astype("category")
sns.swarmplot(x = 'total', y ='is_fat', data = df)

This produced the graph below:

I hope this helps.

For me adding orient="h" as a parameter to my call of swarmplot() solved the problem (see Seaborn docs for reference).
