情节:情节表达遵循什么颜色循环?情节、颜色

我认为默认颜色循环将是(一些变体)['blue', 'red', 'green', 'purple', 'orange'] 就像在情节下面:

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")

至少似乎是循环的顺序，因为从大陆省略 Oceania 会给你这个:

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

现在剩下的颜色的顺序是一样的，除了最后一个橙色的(只是表明颜色的应用不是任意的).

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).

我认为这可以使用 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)']

但是这些颜色的顺序类似于 ['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")?

我也尝试在 help(px.colors) 下查看，但这并没有提供太多帮助:

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

关于 plotly.express 中的模块 plotly.express.colors 的帮助:
