如何修改此 plotly 折线图？

Question

I am very new to plotly. Unable to find answers on its documentation. I created this line chart but i am unable to modify the line chart Example:

1. I want two markers on one line

2. renaming axis and legend

   data_hum = pd.melt(data,id_vars=['time'],value_vars=['hum_1','hum_2']) fig = px.line(data_hum,x='time',y='value',color='variable')

how to create line chart?

Answer 1

I suggest using plotly.graph_objects instead of plotly.express if you want to have more options how to customize your plots.

In your examples this could look something like this

data_hum = pd.melt(data,id_vars=['time'],value_vars=['hum_1','hum_2'])
fig = go.Figure()
fig.add_trace(go.Scatter(x=data_hum['time'], y=data_hum['hum_1'],
                mode='lines+markers',
                name='Legend label 1'))
fig.add_trace(go.Scatter(x=data_hum['time'], y=data_hum['hum_2'],
                    mode='lines+markers',
                    name='Legend label 2'))
