On pyplot I am able to generate the file like object by writing it the object, but I don't know how to put it into Kivy.
推荐答案
您可以使用StringIO将文件保存到缓冲区中(请参阅:).
You could save the file into a buffer with StringIO (see this: Binary buffer in Python).
类似的东西:
from StringIO import StringIO
buff = StringIO()
plt.savefig(buff)
buff.seek(0)
from kivy.core.image.img_pygame import ImageLoaderPygame
imgdata = ImageLoaderPygame(buff)._data
