I would think that the default color cycle would be (some variants of) ['blue', 'red', 'green', 'purple', 'orange'] like in the plot below:
Plot 1:
Code 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")
At least that seems to be the order of the cycle since omitting Oceania from the continents will give you this:
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).
I thought this would be possible to 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)']
But those colors are ordered like ['blue', 'orange', 'green', 'red']...
So, what color cycle does plotly express follow when setting for color="continent" in px.scatter(gapminder2007, x='gdpPercap', y='lifeExp', color="continent")?
I tried looking under help(px.colors) too, but that didn't give much:
