我需要在 python 中以 plotly 更改子图标题,即将其旋转 90 度。我很努力,但没有成功。
这是我的代码
import plotly.offline as pyo
import plotly.graph_objs as go
from plotly import tools
trace1 = go.Bar(
x=[1, 2, 3],
y=[10, 11, 12]
)
trace2 = go.Bar(
x=[1, 2, 3],
y=[100, 110, 120],
)
trace3 = go.Bar(
x=[1, 2, 3],
y=[1000, 1100, 1200],
)
fig = tools.make_subplots(rows=1, cols=3,
shared_xaxes=True, shared_yaxes=True,
vertical_spacing=0.001,
subplot_titles = ('first_title', 'second_title', 'third_title'))
fig.append_trace(trace1, 1, 1)
fig.append_trace(trace2, 1, 2)
fig.append_trace(trace3, 1, 3)
fig['layout'].update(height=600, width=600, title='main_title')
pyo.plot(fig, filename='file.html')

所以,我想旋转'first_title','second_title'并'third_title'通过90度,使得它们不重叠对方。有没有可能解决这个问题?

您可以简单地在该pyo.plot(fig, filename='file.html')行之前添加此代码:
for annotation in fig['layout']['annotations']:
annotation['textangle']=-90

但是,这会导致子情节标题与主标题重叠,因此我建议您将其删除。这是最终的代码:
import plotly.offline as pyo
import plotly.graph_objs as go
from plotly import tools
trace1 = go.Bar(
x=[1, 2, 3],
y=[10, 11, 12]
)
trace2 = go.Bar(
x=[1, 2, 3],
y=[100, 110, 120],
)
trace3 = go.Bar(
x=[1, 2, 3],
y=[1000, 1100, 1200],
)
fig = tools.make_subplots(rows=1, cols=3,
shared_xaxes=True, shared_yaxes=True,
vertical_spacing=0.001,
subplot_titles = ('first_title', 'second_title', 'third_title'))
fig.append_trace(trace1, 1, 1)
fig.append_trace(trace2, 1, 2)
fig.append_trace(trace3, 1, 3)
fig['layout'].update(height=600, width=600, title='')
# rotate all the subtitles of 90 degrees
for annotation in fig['layout']['annotations']:
annotation['textangle']=-90
pyo.plot(fig, filename='file.html')

这个答案链接到Can you alter a subplot title location inplotly? 它寻求正确对齐子图块的答案。
我在 2 x 2 网格上的子图标题上也遇到了类似的问题。答案很简单
fig.update_annotations(yshift=20)
