python - Jupyter 中 bqplot 图形的更紧凑布局

Question

我使用 bqplot 在 Jupyter notebook 中创建了几个图。这些图已使用 Jupyter 小部件 HBox 和 VBox 布局属性进行排列。但是，我无法弄清楚如何在子图行之间获得紧凑的布局。获得更紧密布局的最佳方法是什么？

下面是在 Jupyter 笔记本中运行的 Python 代码示例。

import numpy as np
from bqplot import *
from IPython.display import Javascript, display, clear_output
import ipywidgets as widgets

size = 100
scale = 100.
np.random.seed(0)
x_data = np.arange(size)
y_data = np.cumsum(np.random.randn(size)  * scale)

x_sc = LinearScale()
y_sc = LinearScale()

ax_x = Axis(label='X', scale=x_sc, grid_lines='solid')
ax_y = Axis(label='Y', scale=y_sc, orientation='vertical', grid_lines='solid')

line = Lines(x=x_data, y=x_data, scales={'x': x_sc, 'y': y_sc})

figy=[]
for i in range(2):
    figx=[]
    for j in range(3):
        figx.append(Figure(axes=[ax_x, ax_y], marks=[line], title='Example' + str(i*3+j), fig_margin = dict(top=30, bottom=10, left=20, right=20)))
    figy.append(widgets.HBox(figx)) 
display(widgets.VBox(figy, align_content = 'stretch'))

Answer 1

这是一个解决方案：

import numpy as np
from bqplot import *
from IPython.display import Javascript, display, clear_output
import ipywidgets as widgets

size = 100
scale = 100.
np.random.seed(0)
x_data = np.arange(size)
y_data = np.cumsum(np.random.randn(size)  * scale)

x_sc = LinearScale()
y_sc = LinearScale()

ax_x = Axis(label='X', scale=x_sc, grid_lines='solid')
ax_y = Axis(label='Y', scale=y_sc, orientation='vertical', grid_lines='solid')

line = Lines(x=x_data, y=x_data, scales={'x': x_sc, 'y': y_sc})

fig_layout = widgets.Layout(width='auto', height='auto')

figy=[]
for i in range(2):
    figx=[]
    for j in range(3):
        figx.append(Figure(layout=fig_layout, axes=[ax_x, ax_y], marks=[line], title='Example' + str(i*3+j), fig_margin = dict(top=30, bottom=10, left=20, right=20)))
    figy.append(widgets.HBox(figx))
display(widgets.VBox(figy, align_content = 'stretch'))

基本上覆盖layout了图形的属性。bqplot 图形具有固定的自然高度。

Answer 2

每个HBoxand都有VBox一个 ipywidgetsLayout实例。您可以修改它的属性。
