[英]Plotly: Show hoverinfo in treemap only for child nodes
import pandas as pd
import plotly.express as px
df = pd.DataFrame({'world':['world']*4,
'continent':['SA','SA','NA','NA'],
'country':['Brazil','Uruguay','USA','Canada'],
'total_cases_per_100':[6,1,12,8]})
fig = px.treemap(df, path=['world','continent','country'],values='total_cases_per_100')
fig.update_traces(hovertemplate=None, hoverinfo='value')
The code above gives the following output-上面的代码给出了以下输出 -
As visible, it displays correctly the value of total_cases_per_100
for USA
and all the other child nodes.可见,它正确显示了
USA
和所有其他子节点的total_cases_per_100
的值。 But for parent nodes, it sums it up, which is wrong as total_cases_per_100
is a ratio and not a total.但是对于父节点,它总结了它,这是错误的,因为
total_cases_per_100
是一个比率而不是总数。
Is there anyway I can hide the value
hoverinfo for all nodes except the children?无论如何我可以隐藏除子节点以外的所有节点的
value
hoverinfo 吗?
In case this is not possible, the actual value for the parent nodes is also available with me but I am not sure how I could replace the generated value with it.如果这是不可能的,我也可以使用父节点的实际值,但我不确定如何用它替换生成的值。
You can use hover_data
/ customdata
and override values for none leaf nodes.您可以使用
hover_data
/ customdata
并覆盖非叶节点的值。
import pandas as pd
import plotly.express as px
df = pd.DataFrame({'world':['world']*4,
'continent':['SA','SA','NA','NA'],
'country':['Brazil','Uruguay','USA','Canada'],
'total_cases_per_100':[6,1,12,8]})
leaves = df.select_dtypes("object").apply("/".join, axis=1).values
fig = px.treemap(df, path=['world','continent','country'],values='total_cases_per_100', hover_data=["total_cases_per_100"])
fig.update_traces(hovertemplate='%{customdata[0]}')
fig.data[0].customdata = [
v if fig.data[0].ids[i]
in leaves else [""]
for i, v in enumerate(fig.data[0].customdata)
]
fig
