Bug summary
Calling ax.text with a non-finite x or y fails silently in jupyter notebook
Code for reproduction
I ran into this while trying to label a bunch of lines. Some of my x, y were np.NaN because the lines didn't need to exist. Trimming my x and y is a fine workaround, but it took a while to find the error because it fails silently in jupyter notebook.
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots(1, 2)
for axx in ax:
axx.text(1., 2., 'boo')
axx.text(np.NaN, np.NaN, 'boo!')Fails with
ValueError: posx and posy should be finite values
when calling from the command line. But if I execute the above in a jupyter notebook, it draws the first axis and then drawing silently fails, with no error message.
Expected outcome
I guess that __init__ should check if x and y are finite and fail at that point rather than let the rest of the plot be setup and then fail on draw. However, there is a set_xy method, so maybe it has to wait until draw. In which case, I'm not sure why the error is silent in the notebook backend...
