Description
When I run or save a modified README code in Jupyter, I get a different image than the generated baseline.
Example code run in a Jupyter cell:
#%%file test.py
%matplotlib inline
import matplotlib.pyplot as plt
import pytest
@pytest.mark.mpl_image_compare
def test_succeeds():
fig = plt.figure()
ax = fig.add_subplot(1,1,1)
ax.plot([1,2,3])
fig.savefig("test")
return figRunning test_succeeds(); in Jupyter gives resulting image and saved test.png with margins:
Next, I generate a test.py file by uncommenting the first line, commenting the second line
and then running the cell
%%file test.py
#%matplotlib inline
...From a command prompt, in the appropriate directory I run the following to generate the baseline image:
> py.test --mpl-generate-path=baseline test.py
In the baseline folder, a comparable image called test_succeeds.png is created without margins:
Aside from the difference in sizes, I notice the baseline image uses the classic mpl style. Perhaps this is the cause for the absence in margins. I report this as an issue as it is ideal that when testing the baseline image, it should be the same image as shown and saved by Jupyter.
I tested this with Anaconda 4.2.
