Plotly/如何更改 Plotly 中的默认调色板? [英] Plotly / How to change the default color pallete in Plotly?

问题描述

I was able to force the default theme using

import plotly.io as pio
pio.templates.default = 'plotly_white'

But I am struggling to set a default color palette.

Any ideas how to change this?

Thanks

解决方案

You can add new items to pio.templates.

import plotly.io as pio
import plotly.graph_objects as go
pio.templates["myname"] = go.layout.Template(
    layout=go.Layout(
        colorway=['#ff0000', '#00ff00', '#0000ff']
    )
)
pio.templates.default = 'myname'

EDIT: You can combine themes if you add "+":

pio.templates.default = 'plotly_white+myname'
