将Matplotlib图表嵌入iPython HTML

htmlmatplotlibipythonjupyter-notebook
7
我希望能在Jupyter Notebook的代码单元中动态编写和展示HTML。目标是生成HTML以显示表格、div、img标签，以我选择的方式呈现。我想捕获图像数据，并将其放置在自动生成的HTML中。
到目前为止，我已经发现可以执行以下操作：
from IPython.core.display import HTML

HTML("<h1>Hello</h1>")

并且获得：

你好

太棒了。不过，我希望能够做到这一点：

HTML("<h1>Hello</h1><hr/><img src='somestring'/>")

获取类似于Hello的文本，带有一条水平线和一个图像在下方，其中图像与下面的图像相同。

import pandas as pd
import numpy as np

np.random.seed(314)
df = pd.DataFrame(np.random.randn(1000, 2), columns=['x', 'y'])

df.plot.scatter(0, 1)

enter image description here

结果应该像这样：

enter image description here

问题

我需要用什么来替换'something'才能实现这个功能？更重要的是，我该如何通过Python获取它？

我本来以为图形对象上会有一个属性来保存图像的序列化版本，但我找不到它。

经过一些搜索，感谢 Dmitry B. 指明了正确的方向。

解决方法

from IPython.core.display import HTML
import binascii
from StringIO import StringIO
import matplotlib.pyplot as plt

# open IO object
sio = StringIO()

# generate random DataFrame
np.random.seed(314)
df = pd.DataFrame(np.random.randn(1000, 2), columns=['x', 'y'])

# initialize figure and axis
fig, ax = plt.subplots(1, 1)

# plot DataFrame
ax.scatter(df.iloc[:, 0], df.iloc[:, 1]);

# print raw canvas data to IO object
fig.canvas.print_png(sio)

# convert raw binary data to base64
# I use this to embed in an img tag
img_data = binascii.b2a_base64(sio.getvalue())

# keep img tag outter html in its own variable
img_html = '<img src="data:image/png;base64,{}&#10;">'.format(img_data)

HTML("<h1>Hello</h1><hr/>"+img_html)

我得到的结果是：

piRSquared的回答不再适用于Python 3。我不得不将其更改为：

from IPython.core.display import HTML
import binascii
from io import BytesIO
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

# open IO object
bio = BytesIO()

# generate random DataFrame
np.random.seed(314)
df = pd.DataFrame(np.random.randn(1000, 2), columns=['x', 'y'])

# initialize figure and axis
fig, ax = plt.subplots(1, 1);

# plot DataFrame
ax.scatter(df.iloc[:, 0], df.iloc[:, 1]);

# print raw canvas data to IO object
fig.canvas.print_png(bio)
plt.close(fig)

# convert raw binary data to base64
# I use this to embed in an img tag
img_data = binascii.b2a_base64(bio.getvalue()).decode()

# keep img tag outter html in its own variable
img_html = '<img src="data:image/png;base64,{}&#10;">'.format(img_data)

HTML("<h1>Hello</h1><hr/>"+img_html)

具体来说，我从io中导入，而不是StringIO，并使用BytesIO而不是StringIO。我需要将字节解码为字符串以插入HTML中。我还添加了必需的numpy和pandas导入，使示例图表工作，并添加了plt.close（fig），以便您不会在输出中得到两个图形。

from IPython.core.display import Image
import io

s = io.BytesIO()

# make your figure here

plt.savefig(s, format='png', bbox_inches="tight")
plt.close()

Image(s.getvalue())

我会在其他人（piRSquared）的回答基础上继续讲解，因为在Jupyter和Python 3中它对我不起作用。我编写了以下函数，它将接受我定义的任何绘图函数并调用它，并捕获输出而不在Jupyter中显示它们。我个人使用这个来构建基于许多模型迭代的自定义HTML机器学习报告，我使用Livy和Spark执行这些迭代。
from IPython.core.display import HTML
import binascii
from io import BytesIO
import matplotlib.pyplot as plt
import numpy as np
import base64

def capturePlotHTML(plotFunction): 
    # open IO object
    sio3 = BytesIO() 
    plotFunction()
    plt.savefig(sio3)
    sio3.seek(0)
    data_uri = base64.b64encode(sio3.read()).decode('ascii')
    html_out = '<html><head></head><body>'
    html_out += '<img src="data:image/png;base64,{0}" align="left">'.format(data_uri)
    html_out += '</body></html>'
    #prevents plot from showing in output
    plt.close()
    return (HTML(html_out))


# Plot Wrappers

# Advanced Wrapper for more complex visualizations (seaborn, etc)
class plotRegline:
    def __init__(self):
    #// could also pass in name as arg like this #def __init__(self, name):
        reg_line_prepped_pdf = pandas_input_pdf
        sns.lmplot(x='predicted',y='actual',data=reg_line_prepped_pdf,fit_reg=True, height=3, aspect=2).fig.suptitle("Regression Line")

# Basic Wrapper for simple matplotlib visualizations
def plotTsPred():
        ts_plot_prepped_pdf = pandas_input_pdf
        ts_plot_prepped_pdf.index = pd.to_datetime(ts_plot_prepped_pdf.DAYDATECOLUMN)
        ts_plot_prepped_pdf = ts_plot_prepped_pdf.drop(columns=["DAYDATECOLUMN"])
        ts_plot_prepped_pdf.plot(title="Predicted Vs Actual -- Timeseries Plot -- Days", figsize=(25,6))

#building the plots and capturing the outputs 
regline_html = capturePlotHTML(plotRegline)
ts_plot_day_html = capturePlotHTML(plotTsPred)

# could be any list number of html objects
html_plots =  [regline_html, ts_plot_day_html]
combined_html_plots = display_html(*html_plots)
# the following can be run in this code block or another display the results 
combined_html_plotes
我回到终端前会更彻底地检查这个。谢谢你的答案。 - piRSquared

假设您有base64编码的图像数据：

要在iPython单元格中呈现它，您只需执行以下操作：

from IPython.core.display import Image
Image(data=img_data)

但是我该如何获取img_data？我可以通过检查元素来看到它。但是我该如何通过Python获取它？ - piRSquared
好的，我对问题感到困惑。您是要在iPython中显示 df.plot.scatter(0, 1) 的结果还是其他图像？ 我理解的是您有其他图像想要展示，比如 df.plot.scatter(0, 1)。 - Dmitry B.
你的答案硬编码了 img_data。我想访问一些属性或方法来检索img_data。给我那个就是答案。 - piRSquared
从哪里检索它？！ - Dmitry B.
你从哪里获取了赋给img_data的字符串？我猜你是通过检查输出单元格的HTML并复制该字符串来获取的。但我不能每次想要这样做时都进行检查和复制。我需要以其他方式获取该字符串。 - piRSquared

如果你想在iPython单元格中显示DataFrame.plot的结果，请尝试这样做：
import pandas as pd
import numpy as np
%matplotlib inline


np.random.seed(314)
df = pd.DataFrame(np.random.randn(1000, 2), columns=['x', 'y'])

df.plot.scatter(0, 1)
