在下面添加标题 Python Plotly Choropleth Map
Adding caption below Python Plotly Choropleth Map
我想在我的 plotly choropleth 地图下面添加一个标题(使用 Python)。我研究过使用带有 graph_objs 的注释,但它似乎只适用于地图区域内的位置。有没有办法让注释显示在分区统计图下方 and/or 有没有其他方法可以做到这一点?
现在我得到了这个,但希望标题显示在地图区域下方:
我试过输入小于 0 的 y 值,但文本注释根本不显示。
这是我的代码:
import plotly.graph_objects as go
import pandas as pd
import plotly
df = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/2014_world_gdp_with_codes.csv')
fig = go.Figure(data=go.Choropleth(
locations = df['CODE'],
z = df['GDP (BILLIONS)'],
text = df['COUNTRY'],
colorscale = 'Blues',
autocolorscale=False,
reversescale=True,
marker_line_color='darkgray',
marker_line_width=0.5,
colorbar_tickprefix = '$',
colorbar_title = 'GDP<br>Billions US$',
))
fig.update_layout(
title_text='2014 Global GDP',
geo=dict(
showframe=False,
showcoastlines=False,
projection_type='equirectangular'
),
annotations = [dict(
x=0.5,
y=0, #Trying a negative number makes the caption disappear - I'd like the caption to be below the map
xref='paper',
yref='paper',
text='Source: <a href="https://www.cia.gov/library/publications/the-world-factbook/fields/2195.html">\
CIA World Factbook</a>',
showarrow = False
)]
)
fig.show()
设置 y=-0.1
在我这边工作正常:
情节 1
如果出于某种原因您的情况并非如此(也许是版本问题?),您应该尝试将其保留在 y=0
而不是通过调整边距在图形下方腾出空间情节是这样的:
fig.update_layout(
margin=dict(l=20, r=20, t=60, b=20),
paper_bgcolor="LightSteelBlue")
