Line or marker color repetition if more than 10 traces

[AIMPED]

Hi @michaelyang,

You can change the default color palette to a different pallet with more individual colors, for example alphabet contains 26 colors

Discrete

An example:

import pandas as pd
import plotly.express as px
import numpy as np
import string


df = pd.DataFrame(
    np.random.randint(1,20,size=(26,26)), 
    columns=list(string.ascii_uppercase)
)
fig = px.scatter(
    df, 
    x=df.index,
    y=df.columns,
    color_discrete_sequence=px.colors.qualitative.Alphabet
)
fig.show()
