Plotting multiple subplots, each showing relation between two columns of a pandas DataFrame using Seaborn

I have a pandas DataFrame as follows:

df=pd.DataFrame({'depth':[499,500,501,502,503],'parameter1':[25,29,24,23,25],'parameter2':[72,80,65,64,77]})

I wish to plot multiple (two in this case) seaborn lineplots under the same graph, as subplots. I want to keep the depth parameter constant on the x-axis but vary the y-axis parameters as per the other column values.

sns.relplot(x='depth',y="parameter1",kind='line',data=df)

parameter1 vs depth

sns.relplot(x='depth',y="parameter2",kind='line',data=df)

parameter2 vs depth

I have tried to use seaborn.FacetGrid() but I haven't obtained proper results with these.

Let me know how I can plot these graphs as subplots under a single graph without having to define them individually.

Solution

  • If plotting with pandas is an option, this works:

    df.plot(x= 'depth', layout=(1,2),subplots=True, sharey=True, figsize=(10,4))
plt.show()

    Furthermore, if you would like you can add seaborn styling on top:

    sns.set_style('darkgrid')
df.plot(x= 'depth', layout=(1,2),subplots=True,sharey=True, figsize=(10.5,4))
plt.show()

    Output:
