我需要在python中更改子图标题,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')

因此,我想将'first_title''second_title''third_title'旋转90度,以使它们彼此不重叠。有可能解决这个问题吗?

您只需在pyo.plot(fig, filename='file.html')行之前添加以下代码:

for annotation in fig['layout']['annotations']: 
    annotation['textangle']=-90

但是,这将导致子图标题与主标题重叠,因此建议您删除它。这是最终代码:

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')

这是您得到的: enter image description here

此答案与 Can you alter a subplot title location in plotly? 相关联,后者寻求正确对齐子图块的答案。

我在 2 x 2 网格上遇到了类似的子图标题问题。答案很简单

fig.update_annotations(yshift=20)
