通过添加 'dots' 或某种标记来改进 Plotly 线图 (Python)

Improve Plotly Line Graph by adding 'dots' or some sort of marker to it (Python)

我有一个数据框 df,我在其中创建了一个折线图。我想在折线图中用点来表示它。

示例数据集:

Size       Date         POD

0.027289      11/1/2020     SJ 
0.013563      11/1/2020     SJ 
0.058498      11/1/2020     SJ 
0.281953      11/1/2020     SJ
0.479725      11/1/2020     SJ 
0.007358      11/1/2020     SJ 
0.075818      11/1/2020     SJ
0.069744      11/1/2020     SJ 

这就是我正在做的

 import plotly.express as px
 import plotly.graph_objects as go
 fig = px.line(df1, x = "Date", y = "Size", color = "POD", title = "POD Growth in US", labels = 
 {"Size": "Size in TB"})
 fig.update_layout(
 font_family="Arial",
 font_color="black",
 title_font_family="Arial",
 title_font_color="black",
 legend_title_font_color="black"
  )
 fig.update_xaxes(title_font_family="Arial")
fig.update_layout(
title={
    'text': "POD Growth in US",
    'y':0.9,
    'x':0.5,
    'xanchor': 'center',
    'yanchor': 'top'})


fig.show()

期望的结果是有点

使用mode='lines+markers'。我不确定它是否适用于 line 方法和像素,因为我通常会使用

fig = go.Figure()
fig.add_trace(go.Scatter(
    x = df1["Date"], y = df1["Size"], mode='lines+markers'))
