[Bug]: relativize_data does not take into account sem set to None at experiment definition.

[jultou-raa]

What happened?

When utilizing an output metric with SEM set to None for inference by BOTorch, I encountered a TypeError when using the relativize option in the plot_slice_plotly function.

Error Message:

TypeError: unsupported operand type(s) for ** or pow(): 'NoneType' and 'int'

Cause: The error occurs because the relativize_data function is passing None to the relativize function within the ax.plot.helper method (specifically at line 765).

Expected Behavior: The relativize_data function should handle the None value appropriately, without resulting in a TypeError by using the inferred value.

Please provide a minimal, reproducible example of the unexpected behavior.

You can apply the example from the tutorial page by using relative=True in any function capable of relativizing to the status quo, which will implicitly invoke relativize_data.

Please paste any relevant traceback/logs produced by the example provided.
