Plot multiple DataFrame columns in Seaborn FacetGrid

Question

I am using the following code

import seaborn as sns

g = sns.FacetGrid(dataframe, col=\'A\', hue=\'A\')
g.map(plt.plot, \'X\', \'Y1\')
plt.show()

Answer 1

I used the following code to create a synthetic dataset which appears to match yours:

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

# Generate synthetic data
omega = numpy.linspace(0, 50)

A0s = [1., 18., 40., 100.]

dfs = []
for A0 in A0s:
    V_w_dr = numpy.sin(A0*omega)
    V_w_tr = numpy.cos(A0*omega)
    dfs.append(pandas.DataFrame({'omega': omega,
                                 'V_w_dr': V_w_dr,
                                 'V_w_tr': V_w_tr,
                                 'A0': A0}))
dataframe = pandas.concat(dfs, axis=0)

Then you can do what you want (thanks to @mwaskom in the comments for )sharey='row', margin_titles=True):

melted = dataframe.melt(id_vars=['A0', 'omega'], value_vars=['V_w_dr', 'V_w_tr'])
g = sns.FacetGrid(melted, col='A0', hue='A0', row='variable', sharey='row', margin_titles=True)
g.map(plt.plot, 'omega', 'value')

This results in
