[英]How do I add a title to Seaborn Heatmap?
我想为seaborn热图添加一个标题。 使用Pandas和iPython Notebook
代码如下,
a1_p = a1.pivot_table( index='Postcode', columns='Property Type', values='Count', aggfunc=np.mean, fill_value=0)
sns.heatmap(a1_p, cmap="YlGnBu")
数据非常简单:
In [179]: a1_p
Out [179]:
Property Type Flat Terraced house Unknown
Postcode
E1 11 0 0
E14 12 0 0
E1W 6 0 0
E2 6 0 0
或者,如果您有多sns.plt.suptitle('lalala')
将起作用。
为seaborn heatmap使用提供标题
plt.title("Enter your title", fontsize =20)
或ax.set(title = "Enter your title")
import seaborn as sns # for data visualization
import matplotlib.pyplot as plt # for data visualization
flight = sns.load_dataset('flights') # load flights datset from GitHub seaborn repository
# reshape flights dataeset in proper format to create seaborn heatmap
flights_df = flight.pivot('month', 'year', 'passengers')
ax = sns.heatmap(flights_df) # create seaborn heatmap
plt.title('Heatmap of Flighr Dataset', fontsize = 20) # title with fontsize 20
plt.xlabel('Years', fontsize = 15) # x-axis label with fontsize 15
plt.ylabel('Monthes', fontsize = 15) # y-axis label with fontsize 15
plt.show()
