python - 如何将输出集中在 Python Jupyter 笔记本上？

Question

我有一份在 Jupyter Notebook 中创建的报告。出于美学原因，我希望输出(绘图)居中。

我试过这里给出的答案:

Centering output on IPython notebook

但是这个不行。

我确实发现这个在 Stackoverflow 上有效(Center align outputs in ipython notebook)

CSS = """
.output {
    align-items: center;
}
"""

HTML('<style>{}</style>'.format(CSS))

但是，虽然它使绘图居中，但当绘图很宽并且不需要居中时，它会扩展它并使其比我不想要的页面更宽。我试过像它说的那样调整输出边距区域，但它要么将它再次推到左边，要么将它挤压到需要滚动条的程度(我再次不想那样)

有人有什么建议吗？我认为这将是标准且简单的，但显然不是(如果无法实现我想要的，仅将代码块居中的方法将是一个完美的解决方法？)

即将此表居中:

这是由这段代码产生的:

df = pd.DataFrame(a01) 

new_df01 = df[['Call','FirstReceivedDate','Value']]
new_df01['month'] = pd.Categorical(new_df01['FirstReceivedDate'].dt.strftime('%b'), 
                                         categories=vals, ordered=True) 

groupA01 = new_df01.groupby(['Call']).agg({'Value':sum, 'FirstReceivedDate':'count'}).rename(columns={'FirstReceivedDate':'Count'})
groupA01['Value'] = groupA01['Value'].map('{:,.2f}'.format)

def hover(hover_color="#F1C40F"):
    return dict(selector="tr:hover",
                props=[("background-color", "%s" % hover_color)])

styles2 = [
    hover(),
    dict(selector="th", props=[("font-size", "80%"),
                               ("font-family", "Gill Sans MT"),
                               ("color",'white'),
                               ('background-color', 'rgb(11, 48, 79)'),
                               ("text-align", "center")]),
    dict(selector="td", props=[("font-size", "75%"),
                               ("font-family", "Gill Sans MT"),
                               ("text-align", "center")]),
    dict(selector="tr", props=[("line-height", "11px")]),
    dict(selector="caption", props=[("caption-side", "bottom")])
]


html2 = (groupA01.style.set_table_styles(styles2)
          .set_caption(""))
html2

谢谢!

添加代码以显示热图的绘制:

dfreverse.reverse()

colorscale = [[0,'#FFFFFF'],[0.5, '#454D59'], [1, '#F1C40F']]

y = ['March', 'February', 'January', 'December', 'November', 'October', 'September', 'August', 'July', 'June', 'May', 'April']

hovertext = list()
for yi, yy in enumerate(y):
    hovertext.append(list())
    for xi, xx in enumerate(x):
        hovertext[-1].append('Count: {}<br />{}<br />{}'.format(z[yi][xi],yy, xx))

请试用这个类来使您的图表居中，因为没有提供数据框，我正在创建一个带有随机数据框的图来演示该类的功能。请检查一下。

代码:

from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
from IPython.display import display, HTML
from plotly.graph_objs import *
import numpy as np
init_notebook_mode(connected=True)

display(HTML("""
<style>
.output {
    display: flex;
    align-items: center;
    text-align: center;
}
</style>
"""))
iplot([{"x": [1, 2, 3], "y": [3, 1, 6]}])
iplot([Box(y = np.random.randn(50), showlegend=False) for i in range(45)], show_link=False)
x = np.random.randn(2000)
y = np.random.randn(2000)
iplot([Histogram2dContour(x=x, y=y, contours=Contours(coloring='heatmap')),
       Scatter(x=x, y=y, mode='markers', marker=Marker(color='white', size=3, opacity=0.3))], show_link=False)

输出:
