Plotly:如何为所有子图设置 xticks? [英] Plotly: How to set xticks for all subplots?

问题描述

我无法操纵所有子图上的 xticks.我使用的 xticks 方法(根据文档)仅更改最顶层子图的 xticks.

I am unable to manipulate the xticks on all of my subplots. The method for xticks that I am using (as per documentation) changes the xticks of only the top-most subplot.

我该如何更改下部子图的 xticks?

How can I change the xticks for the lower subplot as well?

下面是我的代码:

fig = make_subplots(rows=2, cols=1)

fig.add_trace(
    go.Scatter(x=np.arange(len(df)), y=df['ro2ofst1 ()'], name='ro2ofst1'),
    row=1, col=1
)

fig.add_trace(
    go.Scatter(x=np.arange(len(df)), y=df['ro2ofst2 ()'], name='ro2ofst2'),
    row=2, col=1
)

fig.update_yaxes(range=[0,300],title='mV',row=1,col=1)
fig.update_yaxes(range=[0,300],title='mV',row=2,col=1)
fig.update_xaxes(title_text='data samples',row=2,col=1)

fig.update_layout(title = 'RO2OFST',
                 xaxis = dict(
                 tickmode = 'linear',
                 tick0=0,
                 dtick=25000))
fig.show()

上面的 fig.update_layout 仅更改第 1 行第 1 列子图的 xticks，但底部子图保留默认 xticks.

The fig.update_layout above changes the xticks only for subplot in row 1 column 1, but the bottom subplot retains the default xticks.

谢谢

推荐答案

您可以访问 fig 中的所有 xaxis 并使用 for 循环设置范围，如下所示:

You can access all xaxis in your fig and set the range using a for loop like this:

myRange=[0,6]
for ax in fig['layout']:
    if ax[:5]=='xaxis':
        fig['layout'][ax]['range']=myRange

剧情:

from plotly.subplots import make_subplots
import plotly.graph_objects as go

fig = make_subplots(rows=3, cols=1)

fig.append_trace(go.Scatter(
    x=[3, 4, 5],
    y=[1000, 1100, 1200],
), row=1, col=1)

fig.append_trace(go.Scatter(
    x=[2, 3, 4],
    y=[100, 110, 120],
), row=2, col=1)

fig.append_trace(go.Scatter(
    x=[0, 1, 2],
    y=[10, 11, 12]
), row=3, col=1)

myRange=[0,6]
for ax in fig['layout']:
    if ax[:5]=='xaxis':
        fig['layout'][ax]['range']=myRange

fig.update_layout(height=600, width=600, title_text="Stacked Subplots")
fig.show()
