Bug summary
Annotation argument has changed from 2.2.3 to 3.0 but I do not think it has been fully documented.
The documentation here is not to date with s still the keyword shown in parameter list (although it has text in the definition) https://matplotlib.org/api/_as_gen/matplotlib.axes.Axes.annotate.html#matplotlib.axes.Axes.annotate
Code for reproduction
#!/usr/bin/env python
import matplotlib
import sys
print(sys.version)
print(matplotlib.__version__)
import matplotlib.pyplot as plt
plt.figure()
a = plt.annotate(s="test", xy=(0.5, 0.5))
print(a)
Actual outcome
Here is the outcome in two different version of matplotlib.
/home/jneal/miniconda3/envs/py36/bin/python /home/jneal/Phd/Codes/annotatetest.py
3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 18:10:19)
[GCC 7.2.0]
2.2.3
Annotation(0.5,0.5,'test')
Process finished with exit code 0
and
3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 18:10:19)
[GCC 7.2.0]
3.0.0
Traceback (most recent call last):
File "annotatetest.py", line 10, in <module>
a = plt.annotate(s="test", xy=(0.5, 0.5))
TypeError: annotate() missing 1 required positional argument: 'text'
Expected outcome
I did not expect it to have changed.
If I change s to text then I have the same problem in reverse if trying to use both versions
( I do know that the arg name can be omitted)
Matplotlib version
conda installed matplotlib from conda-forge
