How can I customize legend colors in Plotly?

How can I customize legend colors in Plotly?

You can customize legend colors in Plotly by using the marker attribute in your trace. For example, you can set the marker colors directly in your data.

Can you show me a code example for that?

Sure! Here's a simple example:

import plotly.graph_objects as go

fig = go.Figure()
fig.add_trace(go.Scatter(x=[1, 2, 3], y=[4, 5, 6], mode='lines', name='Line 1', marker=dict(color='red')))
fig.add_trace(go.Scatter(x=[1, 2, 3], y=[6, 5, 4], mode='lines', name='Line 2', marker=dict(color='blue')))

fig.show()

What if I want to use a color scale instead?

You can use a color scale by setting the marker colors based on a continuous variable. Use colorscale in your trace to achieve this.

Thanks! This is really helpful.
