自动缩放情节`plotly` [英] autoscale the plot `plotly`

问题描述

我需要绘制真实数组和预测数组之间的误差图.我已经设法用 plotly 做到了，如 Code 1 所示，但生成的图在顶部有太多空间.如果我按下图中的 autoscale 按钮 - 它会修复它.

I need to produce a plot of errors between the true and predicted arrays. I've managed to do it with plotly, as shown in Code 1, but the produced plot has too much space on the top. If I press the autoscale button in the plot - it fixes it.

代码 1:

import numpy as np
import plotly.graph_objects as go

N = 40
y1 = np.random.randint(0, 2, N)
y2 = np.random.randint(0, 2, N)
err = np.where(y1 != y2)[0]

fig = go.Figure()

fig.add_trace(
    go.Scatter(
        x=err, 
        y=np.zeros_like(err), 
        name='Prediction Errors', 
        mode='markers', 
        marker_symbol='x', 
        marker_color='red',
        showlegend=True
    )
)
fig.update_layout(title_text = 'Errors in activity prediction', height=10)
fig.update_xaxes(title_text = 'User index', range=[-0.3, N])
fig.update_yaxes(range=[-0.01, 0.1], visible=False)

我的问题:

是否可以自动完成(即不需要我每次都按下autoscale 按钮)?

Can it be done automatically (i.e.without me needing to press the autoscale button each time)?

提前致谢.

推荐答案

您可以尝试以下操作:

fig['layout']['yaxis'].update(autorange = True)
