Multiple marker styles for a line graph

[Francesco_Boraso]

Hello, is there a way to apply different styling to markers on the same line?
I’m logging the prices of an Item and sometimes the price is not available so I’d like to change from a circle marker to a x marker when the price is not available.
I already tried creating two separate lines but they intersect and the result isn’t great

Thanks in advance.

Adding a separate scatter plot doesn’t really help. I just want to change marker type based on a condition

You can specify the markers directly, you would just need to create the marker symbol list beforehand.

import plotly.graph_objects as go

fig = go.Figure()
fig.add_scatter(
    x=[1,2,3], 
    y=[1,2,3], 
    mode="markers+lines",
    marker_symbol=["cross", "circle", "square"],
    marker_size=[10, 20, 30],
    marker_color=["red", "yellow", "black"]
)
fig.show()

import plotly.graph_objects as go

price = [10, 0, 20, 30, 2 , 0]

fig = go.Figure()
fig.add_scatter(
    y=price, 
    x=[*range(len(price))], 
    mode="markers+lines",
    marker_symbol=[["cross", "circle"][item!=0] for item in price],
    marker_color=[["red", "blue"][item!=0] for item in price],

)
fig.update_yaxes(title="price")
fig.show()
