### Informations - **Qiskit Experiments version**: - **Python version**: - **Operating system**: ### What is the current behavior? Error in line 159 of curve_plotter if `y_interp_err` is not a float. I fixed this locally with `if type(y_interp_err) is not float: y_interp_err = 0` however, not sure that's the best way to do this... because there should be some awareness that the interp_err is not getting calculated right ### Steps to reproduce the problem Try to fit a curve to some absurd data ### What is the expected behavior? ### Suggested solutions
