如何将多个Seaborn地块保存到同一pdf / png文件中？

Question

I'm struggling to save the a few plots on the same pdf. The data source is a dataframe. I considered saving them as png, but that is not practical at all..

pdf_pages = PdfPages('kde.pdf')
for i in range(1,114):
    for j in range(0,113):
        x=t1.iloc[:,i]
        y=t1.iloc[:,j]
        fig=sns.jointplot(x=x, y=y, kind="kde",dropna=True);
        pdf_pages.savefig(fig)

Answer 1

Seaborn's jointplot does not return a figure , it returns a seaborn.JointGrid instance.

You need to pass a figure to pdf_pages.savefig , so use:

with PdfPages('kde.pdf') as pdf_pages:
    for i in range(1, 114):
        for j in range(0, 113):
            x=t1.iloc[:, i]
            y=t1.iloc[:, j]
            joint_grid = sns.jointplot(x=x, y=y, kind="kde", dropna=True)
            pdf_pages.savefig(joint_grid.fig)
