密谋:密谋表示什么颜色循环? [英] Plotly: What color cycle does plotly express follow?

问题描述

我认为默认颜色周期将是['blue', 'red', 'green', 'purple', 'orange'](的某些变体)，如下图所示:

I would think that the default color cycle would be (some variants of) ['blue', 'red', 'green', 'purple', 'orange'] like in the plot below:

情节1:

代码1:

import plotly
import plotly.express as px

gapminder = px.data.gapminder()
gapminder2007=gapminder.query("year==2007")
px.scatter(gapminder2007, x='gdpPercap', y='lifeExp', color="continent")

至少似乎是周期的顺序，因为从各大洲中省略Oceania会给您以下信息:

At least that seems to be the order of the cycle since omitting Oceania from the continents will give you this:

现在，其余颜色的顺序是相同的，除了最后一个看起来像橙色的颜色(只是表明颜色的应用不是ribribryry).

Now the order of the remaining colors are the same except for the last orange looking one (just showing that the application of the colors are not aribtrary).

我认为可以使用plotly.colors.DEFAULT_PLOTLY_COLORS进行检索，这将为您提供:

I thought this would be possibleto retrieve using plotly.colors.DEFAULT_PLOTLY_COLORS which will give you:

['rgb(31, 119, 180)',
 'rgb(255, 127, 14)',
 'rgb(44, 160, 44)',
 'rgb(214, 39, 40)',
 'rgb(148, 103, 189)',
 'rgb(140, 86, 75)',
 'rgb(227, 119, 194)',
 'rgb(127, 127, 127)',
 'rgb(188, 189, 34)',
 'rgb(23, 190, 207)']

但是这些颜色的排列方式类似于['blue', 'orange', 'green', 'red']...

But those colors are ordered like ['blue', 'orange', 'green', 'red']...

那么，在px.scatter(gapminder2007, x='gdpPercap', y='lifeExp', color="continent")中设置color="continent"时， 会表现出什么颜色循环?

So, what color cycle does plotly express follow when setting for color="continent" in px.scatter(gapminder2007, x='gdpPercap', y='lifeExp', color="continent")?

我也尝试在help(px.colors)下查看，但这没什么用:

I tried looking under help(px.colors) too, but that didn't give much:

有关plotly.express中的plotly.express.colors模块的帮助:

Help on module plotly.express.colors in plotly.express:

推荐答案

此文档页面涵盖了离散的颜色序列:

This doc page covers discrete color sequences: https://plot.ly/python/discrete-color/ and mentions that the default sequence comes from layout.colorway in the active template.

在名为plotly的默认模板中，这是px.colors.qualitative.Plotly下可用的序列.

In the default template called plotly this is the sequence available under px.colors.qualitative.Plotly.

此顺序为['#636EFA', '#EF553B', '#00CC96', '#AB63FA', '#FFA15A', '#19D3F3', '#FF6692', '#B6E880', '#FF97FF', '#FECB52']
