Cross-posting from Stack Overflow (https://stackoverflow.com/questions/58955557/python-plotly-scatter-specify-line-color-with-integer-value):
Plotly allows a user to specify a color of a marker scatter plot based on an integer value e.g.:
go.Scatter(x=x,
y=y,
mode='markers',
marker=dict(color=i))
where i is an integer. However, if I want to specify the color of a line, neither of the following work:
go.Scatter(x=x,
y=y,
mode='lines',
marker=dict(color=i))
go.Scatter(x=x,
y=y,
mode='lines',
line=dict(color=i))
How do I specify the color of a Plotly Scatter line using an integer?
