如何仅删除图表顶部的空间 - matplotlib

Question

I've seen many posts and answers online trying to answer this question.
However using bbox_inches = 'tight' the legend disappears.

This is one of my figures:

Since I have the legend outside the plot frame, I would like to remove only the top and bottom white space.

Anyone knows how to remove at least the top white space?

Thanks a lot!

Answer 1

I usually don't use the bbox_inches = 'tight' feature, since it doesn't work very reliably, as you already found out. I'd rather produce a PDF with bounds and then crop them using external tools. To do this seamless from python, I use

os.system('pdfcrop %s %s &> /dev/null &'%(pdf_in, pdf_out))

Here, pdf_in is the PDF you produced from matplotlib and pdf_out will be your final result.

Answer 2

Have you tried using subplots_adjust() ? See, for example, the answer of @DaveP to this question: Reduce left and right margins in matplotlib plot

Also, look at the answer by @Tian Chu to the same question.

EDIT: This works for me:

import matplotlib.pyplot as plt
fig=plt.figure()
ax=fig.add_subplot(111)
ax.plot([1,2,3],[5,6,7],'gs-')
plt.subplots_adjust(top=0.99, right=0.99)
plt.show()
