多轴图#
参考:Multiple Axes | Python | Plotly
重要
Plotly Express 不支持在单个图形上使用多个 Y 轴。要制作这样的图形,请使用 make_subplot()
函数与下图所述的图形对象结合使用。
两个 Y 轴#
import plotly.graph_objects as go
from plotly.subplots import make_subplots
go.FigureWidget();
# Create figure with secondary y-axis
fig = make_subplots(specs=[[{"secondary_y": True}]])
# Add traces
fig.add_trace(
go.Scatter(x=[1, 2, 3], y=[40, 50, 60], name="yaxis data"),
secondary_y=False,
)
fig.add_trace(
go.Scatter(x=[2, 3, 4], y=[4, 5, 6], name="yaxis2 data"),
secondary_y=True,
)
# Add figure title
fig.update_layout(
title_text="Double Y Axis Example"
)
# Set x-axis title
fig.update_xaxes(title_text="xaxis title")
# Set y-axes titles
fig.update_yaxes(title_text="<b>primary</b> yaxis title", secondary_y=False)
fig.update_yaxes(title_text="<b>secondary</b> yaxis title", secondary_y=True)
fig.show()
