我正在尝试使用plotly绘制条形图,我想添加标题和字幕。(在这里,您可以选择任意示例来添加标题和字幕)
我绘制条形图的代码:
import plotly.graph_objects as go
fig = go.Figure()
fig.add_trace(go.Bar(x=["Apple", 'Mango', 'Banana'], y=[400, 300, 500]))
fig.show()

Plotly 获取您的字符串并将其作为 HTML 传递。在标题字符串或 X 轴字符串中添加 HTML 可以让您在 ploty 图形对象和 plotly express 中添加一些快速副标题/标题。
<br>
是换行符,<sup>
是上标,可让您快速制作更小的副标题或标题。
图形对象:
import plotly.graph_objects as go
fig = go.Figure()
fig.add_trace(go.Bar(x=["Apple", 'Mango', 'Banana'], y=[400, 300, 500]))
fig.update_layout(
title=go.layout.Title(
text="Plot Title <br><sup>Plot Subtitle</sup>",
xref="paper",
x=0
),
xaxis=go.layout.XAxis(
title=go.layout.xaxis.Title(
text="Fruits<br><sup>Fruit sales in the month of January</sup>"
)
)
)
fig.show()
情节表达:
import plotly.express as px
fig = px.bar(
x=["Apple", 'Mango', 'Banana'],
y=[400, 300, 500],
title = "Plot Title <br><sup>Plot Subtitle</sup>",
labels = {'x':"Fruits<br><sup>Fruit sales in the month of January</sup>",
'y':'count'}
)
fig.show()

使用fig.update_layout(title_text='Your title')
作为标题。字幕没有内置选项。但是您可以通过将x轴标签移到顶部并同时在右下角插入注释来获得所需的效果。我也尝试过使用其他y值,但是似乎没有办法将注释移出图本身。您还可以更改标题和字幕的字体,以使其在其余标签中脱颖而出。
情节:
代码:
import plotly.graph_objects as go
fig = go.Figure()
fig.add_trace(go.Bar(x=["Apple", 'Mango', 'Banana'], y=[400, 300, 500]))
fig.update_layout(title=go.layout.Title(text="Caption", font=dict(
family="Courier New, monospace",
size=22,
color="#0000FF"
)))
fig.update_layout(annotations=[
go.layout.Annotation(
showarrow=False,
text='Subtitle',
xanchor='right',
x=1,
xshift=275,
yanchor='top',
y=0.05,
font=dict(
family="Courier New, monospace",
size=22,
color="#0000FF"
)
)])
fig['layout']['xaxis'].update(side='top')
fig.show()

也许是这样吗?
import plotly.graph_objects as go
fig = go.Figure()
fig.add_trace(go.Bar(x=["Apple", 'Mango', 'Banana'], y=[400, 300, 500]))
fig.update_layout(
title=go.layout.Title(
text="Plot Title",
xref="paper",
x=0
),
xaxis=go.layout.XAxis(
title=go.layout.xaxis.Title(
text="x Axis",
font=dict(
family="Courier New, monospace",
size=18,
color="#7f7f7f"
)
)
),
yaxis=go.layout.YAxis(
title=go.layout.yaxis.Title(
text="y Axis",
font=dict(
family="Courier New, monospace",
size=18,
color="#7f7f7f"
)
)
)
)
fig.show()
