参数textangle为您完成。来自 plotly 文档的示例。textangle=-90如何设置旋转注释。
代码:
# import necessaries libraries
import numpy as np
import plotly.offline as py
import plotly.graph_objs as go
z = np.random.randint(1000, 11000, size=20)
# Create a trace
trace = dict(type='scatter',
x=3+np.random.rand(20),
y=-2+3*np.random.rand(20),
mode='markers',
marker=dict(color=z, colorscale='RdBu',
size=14, colorbar=dict(thickness=20)))
# Define axis_style
axis_style = dict(zeroline=False, showline=True, mirror=True)
# Specify layout style
layout = dict(width=550, height=500,
xaxis=axis_style,
yaxis=axis_style,
hovermode='closest',
)
# Update layout with annotation
layout.update(
annotations=[dict(
# Don't specify y position,because yanchor="middle" do it for you
x=1.22,
align="right",
valign="top",
text='Colorbar Title',
showarrow=False,
xref="paper",
yref="paper",
xanchor="right",
yanchor="middle",
# Parameter textangle allow you to rotate annotation how you want
textangle=-90
)
]
)
# Create FigureWidget
fig = go.FigureWidget(data=[trace], layout=layout)
# Plot fig
py.plot(fig)
