Now I remember the issue with: if not np.iterable(positions):
positions = [positions]This deals with e.g. scalars, but will break later on in EventCollection with: if np.ndim(positions) != 1:
raise ValueError('positions must be one-dimensional')Are there any inputs that are not |

Because of the code above, this cannot happen.

This is added compared to the discussion we had. For similar behavior and it will still break with unequal sizes below.
An option is to skip all these len() == 0 checks, except for colors, and rely on the unequal size below. Fewer checks, but slightly worse error message.

PR Summary
This is not finalized, but more a base for discussion. (Tests will be added once the final solution is decided.)
Closes #7560
There are two issues that are considered here:
eventplot(1)), but one can also consider raising an error with an appropriate error message already there.Finally, an if-statement that I cannot see can even be triggered is removed.
(Issue 2 and the removal came from trying to test these lines, which lead me to find #7560 and the earlier attempts to fix it.)
