问题描述
plotly.express 非常方便生成漂亮的交互式绘图.下面的代码生成按国家/地区着色的折线图.现在我需要在情节中添加点.有谁知道我如何向折线图添加点?
将 plotly.express 导入为 pxgapminder = px.data.gapminder().query("大陆=='大洋洲'")fig = px.line(gapminder, x="year", y="lifeExp", color='country')图.show()
解决方案
更新:
截至版本
代码:
将 plotly.express 导入为 pxgapminder = px.data.gapminder().query("continent=='Oceania'")fig = px.line(gapminder, x="year", y="lifeExp", color='country')fig.update_traces(mode='markers+lines')图.show()
plotly.express is very convenient to produce nice interactive plots. The code below generates a line chart colored by country. Now what I need is to add points to the plot. Does anyone know how I can add points to the line chart?
import plotly.express as px
gapminder = px.data.gapminder().query("continent=='Oceania'")
fig = px.line(gapminder, x="year", y="lifeExp", color='country')
fig.show()
解决方案
Update:
As of version 5.2.1
you can use markers=True
in:
px.line(df, x='year', y='lifeExp', color='country', markers=True)
Previous answer for older versions:
Use fig.update_traces(mode='markers+lines')
Plot:
Code:
import plotly.express as px
gapminder = px.data.gapminder().query("continent=='Oceania'")
fig = px.line(gapminder, x="year", y="lifeExp", color='country')
fig.update_traces(mode='markers+lines')
fig.show()
