一個用於Seaborn FacetGrid子圖的共享x軸標籤（佈局/間距？）

Question

我想爲x軸添加一個標籤，併爲y軸添加一個標籤。

此外，顏色條標題多一點的彩色條空間的提示將不勝感激。

我標誌着可以使用幫助與# <---- Help Please!

g.set_titles(col_template="{col_name}", 
      fontweight='bold', fontsize=18) 
g.fig.subplots_adjust(right=.9) # Add space so the colorbar doesn't overlap the plot 

# ---- add one label for x axis and one for y-axis ----- 

g.fig.text(0.4, 0.1, s='way too high!',fontdict={'fontsize':16}) # <---- Help Please! 
plt.figtext(0.4,0.02,"this looks bad",fontdict={'fontsize':16}) # <---- Help Please! 
# add y-axis label too  [enter image description here][1]# <---- Help Please! 

注意的地方：我建立對this post頂部，並增加了一些好用的東西，如supertitle，旋轉的X標籤，彩條的標題。

根據@mwaskom的評論，您必須使用g.fig.text()來添加標籤並g.fig.subplots_adjust()在左側和底部添加空間以避免重疊。
