[英]Adding y-axis on right side to Ridge Plot in Seaborn
如果您想從 FacetGrid 修改一個特定的軸,您可以從列表g.axes
獲取參考
這是我將如何去做
import numpy as np
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
sns.set(style="white", rc={"axes.facecolor": (0, 0, 0, 0)})
# Create the data
rs = np.random.RandomState(1979)
x = rs.randn(500)
g = np.tile(list("ABCDEFGHIJ"), 50)
df = pd.DataFrame(dict(x=x, g=g))
m = df.g.map(ord)
df["x"] += m
# Initialize the FacetGrid object
pal = sns.cubehelix_palette(10, rot=-.25, light=.7)
g = sns.FacetGrid(df, row="g", hue="g", aspect=15, height=.5, palette=pal)
# Draw the densities in a few steps
g.map(sns.kdeplot, "x", clip_on=False, shade=True, alpha=1, lw=1.5, bw=.2)
g.map(sns.kdeplot, "x", clip_on=False, color="w", lw=2, bw=.2)
g.map(plt.axhline, y=0, lw=2, clip_on=False)
# Define and use a simple function to label the plot in axes coordinates
def label(x, color, label):
ax = plt.gca()
ax.text(0, .2, label, fontweight="bold", color=color,
ha="left", va="center", transform=ax.transAxes)
g.map(label, "x")
#
# Changes from seaborn example below this point
#
# Set the subplots to overlap
g.fig.subplots_adjust(hspace=-.25, right=0.9)
# Remove axes details that don't play well with overlap
g.set_titles("")
#g.set(yticks=[])
g.despine(bottom=True, left=True, right=False, top=True, offset=5)
for ax in g.axes.ravel():
if ax.is_first_row(): # can use .is_last_row() to show spine on the bottom plot instead
ax.yaxis.tick_right()
ax.yaxis.set_label_position("right")
ax.set_ylabel("MW")
else:
ax.spines['right'].set_visible(False)
[l.set_visible(False) for l in ax.get_yticklabels()] # necessary because y-axes are shared
