Python 如何在绘图本身之外注释点?
我有一个这样的情节,想在上面加上“今天”的文字 我在尝试注释Python 如何在绘图本身之外注释点?,python,plot,plotly,Python,Plot,Plotly,我有一个这样的情节,想在上面加上“今天”的文字 我在尝试注释 annots.append(dict(x='2020-03-29',y=len(df)+1,text='<b>Today<b>', showarrow=False, font=dict(color='black'))) annots.append(dict(x='2020-03-29',y=len(df)+1,text='Today',showarrow=False,font=dict(color='bla
annots.append(dict(x='2020-03-29',y=len(df)+1,text='<b>Today<b>', showarrow=False, font=dict(color='black')))
annots.append(dict(x='2020-03-29',y=len(df)+1,text='Today',showarrow=False,font=dict(color='black'))
但是输出是这样的,我希望它在绘图上面,而不是改变绘图的结构!
您可以通过三个步骤完成此操作:
fig.update\u布局(margin=dict())
图添加线。添加_形()
add_注释(yref='paper',y=1.06)
在绘图外部添加文本,例如y>1
将注释放置在绘图本身上方# imports
