Description
Bug summary
I want to cycle between multiple markerstyles, including those with a numeric value like CARETRIGHT as documentedhere, but I get an exception if I add one of those.
Code for reproduction
#!/usr/bin/env python3fromcyclerimportcyclerimportmatplotlib.pyplotaspltimportmatplotlib.markersasmkcycle=cycler(marker=["+",mk.CARETRIGHT])t=[0,1]y=[5,6]plt.rc('axes',prop_cycle=cycle)plt.plot(t,y)plt.show()
Actual outcome
Traceback (most recent call last): File "/home/mcd/bugs/bug-cycler.py", line 11, in <module> plt.rc('axes', prop_cycle=cycle) File "/usr/lib/python3.11/site-packages/matplotlib/pyplot.py", line 670, in rc matplotlib.rc(group, **kwargs) File "/usr/lib/python3.11/site-packages/matplotlib/__init__.py", line 1062, in rc rcParams[key] = v ~~~~~~~~^^^^^ File "/usr/lib/python3.11/site-packages/matplotlib/__init__.py", line 734, in __setitem__ raise ValueError(f"Key {key}: {ve}") from NoneValueError: Key axes.prop_cycle: Could not convert 5 to strExpected outcome
A plot using CARETLEFT as marker.
Additional information
This seems like it has to do with the fact, that some markers are referred to by number and not by a string like "+".
I don't know whether the problem is in matplotlib, cycler or the combination of both.
