When adding traces to fig=px.scatter() does it have to be added with fig.add_traces(go.Scatter())?

问题

当向 fig=px.scatter() 添加 traces 时,是否必须使用 fig.add_traces(go.Scatter())?

我问这个问题是因为在 px.scatter 和 go.scatter 之间存在微妙的差异,对我来说很难记住(令人讨厌)。另外,使用其中一个是否更好/更全面?

我觉得我应该能够以创建原始 traces 的相同方式添加 traces?即,fig.add_traces(px.Scatter())。这样可以减少记住所有输入的工作。我漏掉了什么吗?

When adding traces to fig=px.scatter() does it have to be added with fig.add_traces(go.Scatter())?

I ask this because it gets very confusing with the subtle differences, that are a PIA to remember (for me), between px.scatter and go.scatter. Also, is it better/more comprehensive to use one or the other?

I feel like I should be able to add the traces the same way the original ones were created? i.e., fig.add_traces(px.Scatter()). That would cut down on remembering all the inputs. Am I missing something?

here is my sample code:

df  = pd.DataFrame({'x':[1,2,3,4],'y':[1,1,1,1],'z':[10,10,10,10],'custom':[30,30,30,30]})
df2 = pd.DataFrame({'x':[1,2,3,4],'y':[2,2,2,2],'z':[15,15,15,15],'custom':[40,40,40,40]})

fig = px.scatter(df, 
                 x='x', 
                 y='y',
                 size='z',
                 size_max=10,
                 custom_data=['custom'],
                 color_discrete_sequence=['red'],
                 )

fig.update_traces(
    hovertemplate="<br>".join([
        "x: %{x}",
        "some custom data: %{custom_data[0]}",
    ])
)

fig.add_traces(go.Scatter(  x=df2['x'], 
                            y=df2['y'],
                            mode='markers',
                            customdata=df2['custom'],
                            marker=dict(size=7, 
                                        symbol='circle', 
                                        color='blue',
                 )))

fig.update_traces(
    hovertemplate="<br>".join([
        "x: %{x}",
        "some custom data: %{customdata}",
    ])
)
fig.show()

Thanks!

如果您在fig.add_traces(go.Scatter())中感到困惑,您可以改用以下方式:

fig.add_scatter

或者您可以使用通过运行dir(go.Figure())显示的其他任何方法,比如:

add_bar
add_barpolar
add_box
add_candlestick

完整的代码:

import plotly.graph_objects as go
fig = go.Figure()
dir(fig)
英文:

If it's the go.Scatter() part that you find confusing in fig.add_traces(go.Scatter()) then you can use this instead:

fig.add_scatter

Or you can use any of the other methods that will reveal themselves by running dir(go.Figure()), such as:

 add_bar
 add_barpolar
 add_box
 add_candlestick

Complete code:

import plotly.graph_objects as go
fig = go.Figure()
dir(fig)

这是一个仅使用Plotly Express的解决方案。

import pandas as pd
import plotly.express as px

df  = pd.DataFrame({'x':[1,2,3,4],'y':[1,1,1,1],'z':[10,10,10,10],'custom':[30,30,30,30]})
df2 = pd.DataFrame({'x':[1,2,3,4],'y':[2,2,2,2],'z':[15,15,15,15],'custom':[40,40,40,40]})

fig = px.scatter(df, 
                 x='x', 
                 y='y',
                 size='z',
                 size_max=10,
                 hover_data=['custom'],
                 color_discrete_sequence=['red'],
                 )

fig2 = px.scatter(df2, 
                 x='x', 
                 y='y',
                 hover_data=['custom'],
                 color_discrete_sequence=['blue'],
                 )

fig2.update_traces(marker=dict(
                                size=7, 
                                symbol='circle', 
                                color='blue',
                     ))

# 将fig2的所有轨迹添加到fig中
fig.add_traces(fig2.data)
fig.show()

Here is a plotly express only solution.

import pandas as pd
import plotly.express as px

df  = pd.DataFrame({'x':[1,2,3,4],'y':[1,1,1,1],'z':[10,10,10,10],'custom':[30,30,30,30]})
df2 = pd.DataFrame({'x':[1,2,3,4],'y':[2,2,2,2],'z':[15,15,15,15],'custom':[40,40,40,40]})

fig = px.scatter(df, 
                 x='x', 
                 y='y',
                 size='z',
                 size_max=10,
                 hover_data=['custom'],
                 color_discrete_sequence=['red'],
                 )

fig2 = px.scatter(df2, 
                 x='x', 
                 y='y',
                 hover_data=['custom'],
                 color_discrete_sequence=['blue'],
                 )

fig2.update_traces(marker=dict(
                                size=7, 
                                symbol='circle', 
                                color='blue',
                     ))

# Add all the traces from fig2 to fig
fig.add_traces(fig2.data)
fig.show()
