Hide legend from seaborn pairplot

You need to return the Seabron Pairgrid object when you use pairplot and then you can access the legend of the Pairgrid using ._legend. Then simply call remove():

import seaborn as sns

test = pd.DataFrame({
    'id': ['1','2','1','2','2','6','7','7','6','6'],
    'x': [123,22,356,412,54,634,72,812,129,110],
    'y':[120,12,35,41,45,63,17,91,112,151]})

g = sns.pairplot(x_vars='x', y_vars="y", data=test, hue = 'id', height = 3)
g._legend.remove()

Since _legend.remove() method won't work on some other seaborn plots, what about:

plt.legend([],[], frameon=False)
