我想在 Jupyter Notebook 中创建一个Holoviz 面板仪表板,其中包含一个 seaborn 条形图。我可以让仪表板成功显示 matplotlib 图,但不显示 seaborn 图- 只是一些文本 ( AxesSubplot(0.125,0.125;0.775x0.755)
)。
我在 Holoviz 网站上查看了一些示例,并搜索了 seaborn 特定示例,但找不到任何示例。我还搜索了 StackOverflow 和 Google,但没有找到任何可以告诉我如何成功显示 seaborn 绘图的内容。
我的代码:
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
import panel as pn
import hvplot as hv
# create a data set of animal ratings
df = pd.DataFrame({'Animal':['Pig', 'Goat' ,'Sheep', 'Frog', 'Goat', 'Goat', 'Pig', 'Sheep', 'Octopus'],
'Rating':[3, 10, 3, 2, 9, 10, 4, 1, 1]})
# define the holoviz panel parameter selector and plots in a class
class RatingsDashboard(param.Parameterized):
# widget containing the list of animals
Animal = param.ObjectSelector(default='Goat', objects=list(df.Animal.unique()))
title = 'Ratings for '
xlabel = 'Rating'
ylim = (0, 3)
def get_data(self):
class_df = df[(df.Animal==self.Animal)].copy()
return class_df
def hist_view_all(self):
plot = plt.figure()
plot.add_subplot(111).hist(df['Rating'])
plt.close(plot)
return plot
# seaborn strip plot for all ratings for all animals
def strip_view_all(self):
plot = sns.stripplot(data = df, x='Animal', y='Rating', jitter=False, size=10)
return plot
def hist_view(self):
data = self.get_data()
title = "Histogram: " + self.title
plot = plt.figure()
plot.add_subplot(111).hist(data['Rating'])
plt.title('Histogram of ' + self.title + self.Animal, size=14)
plt.xlabel(self.xlabel, size=14)
plt.xticks(size=12)
plt.yticks(size=12)
plt.ylim(self.ylim)
plt.close(plot)
return plot
def table_view(self):
data = self.get_data()
return data
# create an instance of the class
rd = RatingsDashboard(name='')
# define the dashboard elements using a subset of the rd class plots
dashboard3 = pn.Column('## Animal Ratings', rd.strip_view_all, rd.param,
pn.Row(rd.hist_view, rd.table_view))
# display the dashboard
dashboard3
