如何在 jupyter/matplotlib 图形下方添加乳胶图形标题 [英] How to add latex figure captions below jupyter / matplotlib figures

问题描述

在 jupyter notebook 中，有没有办法在每个内联 matplotlib 图形下方添加乳胶图形标题?这是需要的，以便在运行 nbconvert --to latex 时对每个图形进行注释.

From within the jupyter notebook, is there a way to add latex figure caption below each inline matplotlib figure? This is desired so that each figure is annotated when running nbconvert --to latex.

但我不清楚如何相对于在 egin{verbatim} 块中结束的图形定位 LaTeX.我可以将它放在情节之后的降价单元格中；但是，这并没有像我想要的那样包装数字.

But I am not clear on how to position the LaTeX relative to the figure which ends up in egin{verbatim} block. I can place it in a markdown cell just after the plot; but, that does not wrap the figure as I want.

推荐答案

有点变通方法，但是下面的辅助函数调用 plt.close() 来阻止显示内联图形，只留下为图形生成的 LaTeX 块.

A bit of a workaround but the following helper function calls plt.close() to keep the inline figures from being displayed leaving only the generated LaTeX block for the figure.

bShowInline = True  # Set = False for document generation

def makeplot( plt, figlabel, figcaption):
    figname = figlabel+'.png'

    plt.savefig(figname)

    if bShowInline:
        plt.show()
    else:
        plt.close()

    strLatex="""
    \begin{figure}[b]
    centering
        includegraphics[totalheight=10.0cm]{%s}
        caption{%s}
        label{fig:%s}
    end{figure}"""%(figname, figcaption, figlabel) 
    return display(Latex(strLatex)) 

有没有更清洁的方法?
