我有以下代码用Plotly创建线图。如何将Y轴的范围设置为始终在[0; 10]?
layout = go.Layout(
title=go.layout.Title(
text="Test",
xref='paper',
x=0
),
xaxis=go.layout.XAxis(
tickmode='linear',
tickfont=dict(
size=10
),
title=go.layout.xaxis.Title(
font=dict(
size=14,
color='#7f7f7f'
)
)
),
yaxis=go.layout.YAxis(
title=go.layout.yaxis.Title(
text=y,
font=dict(
size=14,
color='#7f7f7f'
)
)
)
)
data = [go.Scatter(x=x1, y=y1)]

如果我理解的正确,您想限制y轴本身的范围。您可以在关键字参数yaxis
中传递字典。可能像go.Layout(yaxis=dict(range=[0, 10]))
之类的东西,希望对您有所帮助。

使用layout = go.Layout(yaxis=dict(range=[fromValue, toValue])

Jupyter Notebook的完整代码:
# imports
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
import pandas as pd
import plotly.graph_objs as go
import numpy as np
# setup
init_notebook_mode(connected=True)
# data
np.random.seed(4)
x = np.linspace(0, 1, 50)
y = np.cumsum(np.random.randn(50))
# line
trace = go.Scatter(
x=x,
y=y,
)
# layout
layout = go.Layout(yaxis=dict(range=[-4,4])
)
# Plot
fig = go.Figure(data=[trace], layout=layout)
iplot(fig)
一些重要的详细信息:
通过此设置,您可以轻松地添加y轴标题,如下所示:
# layout
layout = go.Layout(yaxis=dict(range=[-4,4]), title='y Axis')
)
如果您想进一步格式化该标题,这会有点困难。我发现最简单的方法是使用title = go.layout.yaxis.Title(text='y Axis', font=dict(size=14, color='#7f7f7f')
添加另一个元素。只要您以正确的方式进行操作,就不会在上面的评论中遇到这种情况:
谢谢。我尝试过这个。但是然后我在yaxis中有2个定义 布局:yaxis = dict(range = [0,10])和yaxis = go.layout.YAxis。因此 出现错误。
看看这个:
