我想在Ridge图的右侧添加一个示例y轴刻度,以了解所有图的值范围是多少。最好,我只想将其添加到其中一个子图中,而不是所有子图中。
我的情节是基于https://seaborn.pydata.org/examples/kde_ridgeplot.html
上最原始的“山脊情节”示例我已经尝试了以下方法,但是没有运气:
g.set(yticks=[0,200])
g.set_y_label_position("right")
g.set_ylabels('[Range]',fontsize=9,fontweight="normal")
答案 0 :(得分:0)
如果要从FacetGrid修改一个特定的轴,则可以从列表g.axes
中获取参考
这就是我要怎么做
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
