Bug summary
With Matplotlib 3.8+ I'm seeing spurious lines that get added with manually labeled contours via clabel.
It seems to only happen in locations where the contours are more complex or near those areas, but I haven't been able to track down why this happens.
Code for reproduction
Example code (here working with Matplotlib <3.8): https://geocat-examples.readthedocs.io/en/latest/gallery/Contours/NCL_coneff_8.html
I'll work on stripping down this example though.Actual outcome
when run in a script that provided a manual list of contour label locations:
when locations were manually clicked:
Expected outcome
similar, but without the spurious straight lines.
Additional information
What are the conditions under which this bug happens?
- happens with both "clicked" and specified manual contour labels in certain locations
- seems to happen only near areas with more complex contours
- interestingly, this also happens when you specify contour label locations this way on a cartopy map and the specified points are not on the projected map. however, this is not the case here.
Has this worked in earlier versions? - worked prior to 3.8
Do you know why this bug is happening? - unfortunately, no. will look into it a bit more though.
