px.funnel给每个阶段加转化率的值
时间: 2024-03-09 09:48:35 浏览: 24
要在 `px.funnel` 中给每个阶段加上转化率的值,可以使用 `px.funnel(df, x='stage', y='number', color='stage', text='conversion_rate')` 命令。其中 `df` 是一个包含阶段、数量和转化率的 `pandas.DataFrame`,`x` 是阶段的列名,`y` 是数量的列名,`color` 是阶段的列名,`text` 是转化率的列名。这样,在绘制漏斗图时,每个阶段的转化率就会在该阶段的标签旁边显示出来。例如:
```
import plotly.express as px
import pandas as pd
df = pd.DataFrame({'stage': ['访问网站', '注册账号', '创建订单', '支付订单'],
'number': [1000, 500, 200, 100],
'conversion_rate': [100, 50, 25, 50]})
fig = px.funnel(df, x='stage', y='number', color='stage', text='conversion_rate')
fig.show()
```
这个代码会绘制一个包含4个阶段的漏斗图,每个阶段的标签旁边都会显示该阶段的转化率。

导入python中px.funnel可视化函数
要导入Python中的px.funnel可视化函数,您需要使用plotly.express模块。您可以按照以下步骤导入该模块并使用px.funnel函数:
```
import plotly.express as px
# 创建一个数据集
data = dict(
number=[20, 14, 10, 7],
stage=["访问", "注册", "付费", "留存"]
)
# 使用px.funnel函数创建漏斗图
fig = px.funnel(data, x='number', y='stage')
# 显示漏斗图
fig.show()
```
请注意,您需要先安装plotly库才能使用plotly.express模块。您可以使用以下命令安装plotly库:
```
pip install plotly
```
px.funnel的name 'px' is not defined
This error message means that you are trying to access the attribute 'funnel' of an object named 'px', but the variable 'px' has not been defined in your code.
To fix this error, you need to first define the variable 'px' and assign it to an object that has a 'funnel' attribute. For example:
```python
class MyClass:
funnel = "example funnel"
px = MyClass()
print(px.funnel)
```
This will create an instance of the `MyClass` class, assign it to the variable `px`, and then access its `funnel` attribute to print "example funnel".
Make sure that you have defined the object correctly and that the variable name is spelled correctly in your code.
