Seaborn 热图上 y 轴刻度的垂直对齐

我正在策划一个Seaborn heatmap我想将y-axis勾选标签，但找不到方法来做到这一点。'va'文本属性似乎不可用yticks().

考虑到以下几点image

I'd like to align the days of the week to the center of the row of squares

Code生成此图：

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

#Generate dummy data
startDate = '2017-11-25'
dateList = pd.date_range(startDate, periods=365).tolist()
df = pd.DataFrame({'Date': dateList,
                'Distance': np.random.normal(loc=15, scale=15, size=(365,))
              })
#set week and day
df['Week'] = [x.isocalendar()[1] for x in df['Date']]
df['Day'] = [x.isocalendar()[2] for x in df['Date']]

#create dataset for heatmap
#group by axis to plot
df = df.groupby(['Week','Day']).sum().reset_index()
#restructure for heatmap
data = df.pivot("Day","Week","Distance")

#configure the heatmap plot
sns.set()
fig, ax = plt.subplots(figsize=(15,6))
ax=sns.heatmap(data,xticklabels=1,ax = ax, robust=True, square=True,cmap='RdBu_r',cbar_kws={"shrink":.3, "label": "Distance (KM)"})
ax.set_title('Running distance', fontsize=16, fontdict={})

#configure the x and y ticks
plt.xticks(fontsize="9")
plt.yticks(np.arange(7),('Mon','Tue','Wed','Thu','Fri','Sat','Sun'), rotation=0, fontsize="10", va="center")

#set labelsize of the colorbar
cbar = ax.collections[0].colorbar
cbar.ax.tick_params(labelsize=10)

plt.show()

Adding +0.5 to np.arange(7) in the plt.yticks()为我工作

plt.yticks(np.arange(7)+0.5,('Mon','Tue','Wed','Thu','Fri','Sat','Sun'),
           rotation=0, fontsize="10", va="center")
