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.

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中text的字体大小设置
您可以通过设置 `textStyle` 属性来控制 px.funnel 中 `text` 的字体大小。例如:
```javascript
option = {
series: [{
type: 'funnel',
data: [...],
label: {
show: true,
position: 'inside',
textStyle: {
fontSize: 14 // 设置字体大小为14
}
}
}]
}
```
在上面的示例中,`textStyle` 中的 `fontSize` 属性被设置为 14,这会将 `text` 的字体大小设置为 14。您可以根据需要进行适当的更改。
