from bokeh.plotting import figure, show, output_file import numpy as np import pandas as pd import pandas df = pd.read_csv(r'/Users/fuchuanruo/Desktop/可视化作业/实践/train.csv') test = pd.read_csv(r'/Users/fuchuanruo/Desktop/可视化作业/实践/test.csv')

计算housing和default关系

housing_default = df.groupby('housing')['default'].value_counts(normalize=True).unstack() housing_default

创建绘图空间

p = figure(x_range=housing_default.index.tolist(), plot_height=350, title='Housing vs Default', toolbar_location=None, tools="")

添加柱状图

p.vbar_stack(housing_default.columns.tolist(), x='housing', width=0.9, color=['#c9d9d3', '#718dbf'], source=housing_default, legend_label=housing_default.columns.tolist())

设置图例位置

p.legend.location = 'top_right' p.legend.orientation = 'vertical'

设置x轴标签

p.xaxis.axis_label = 'Housing'

设置y轴标签

p.yaxis.axis_label = 'Percentage'

输出图像

output_file('housing_default.html') show(p)
