将颜色条移近热图(Seaborn)
Move Colorbar closer to Heatmap (Seaborn)
我的颜色条离热图底部很远。有没有办法把它移近一点?
我的代码是:
import seaborn as sns
Granger2 = Granger
Granger2.columns = Granger_colnames
Granger2.index = Granger_rownames
fig, ax = plt.subplots(figsize=(6,25))
sns.heatmap(Granger2, cmap=rvb, cbar=True, ax=ax,linewidths=.5,cbar_kws={"orientation": "horizontal"})
ax.xaxis.tick_top() # x axis on top
ax.xaxis.set_label_position('top')
#Remove ticks
ax.tick_params(axis='both', which='both', length=0)
# Drawing the frame
ax.axhline(y = 0, color='k',linewidth = 1)
ax.axhline(y = Granger2.shape[0], color = 'k',linewidth = 1)
ax.axvline(x = 0, color = 'k', linewidth = 1)
ax.axvline(x = Granger2.shape[1], color = 'k', linewidth = 1)
plt.show()
您可以使用例如cbar_kws={"orientation": "horizontal", "pad":0.02}
。填充是子图高度的一小部分,因此 0.02 是 2%。有关 pad
和其他参数的更多信息,请参阅 colorbar docs。
import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd
sns.set_style('whitegrid')
flights = sns.load_dataset('flights')
flights = flights.pivot('year', 'month').droplevel(0, axis=1)
fig, ax = plt.subplots(figsize=(6, 20))
sns.heatmap(flights, cmap='Greens', cbar=True, ax=ax, linewidths=.5,
cbar_kws={"orientation": "horizontal", "pad": 0.02})
ax.xaxis.tick_top() # x axis on top
ax.xaxis.set_label_position('top')
# Remove ticks
ax.tick_params(axis='both', which='both', length=0)
# Drawing the frame
ax.patch.set_edgecolor('0.15')
ax.patch.set_linewidth(2)
plt.tight_layout()
plt.show()
