python - How to change the path of matplotlib.pyplot.save

Question

By default, it is always saved in the same folder as the py file. How can I change the path and save the generated image on the path I want?

Answer 1

In matplotlib, pyplot does not have a save function. If you want to save a picture, you can refer to the following simple example:

>>> from matplotlib import pyplot as plt
>>> x=[2,5]
>>> y=[4,9]
>>> plt.plot(x,y)
>>> plt.savefig('D:\img.jpg')

Of course you can also save it in PDF format:

>>> plt.savefig('D:\img.pdf')

matplotlib will handle this part of the work automatically.
