Eomys / SciDataTool

SciDataTool is an open-source Python package for scientific data handling. The objective is to provide a user-friendly, unified, flexible module to postprocess any kind of signal. It is meant to be used by researchers, R&D engineers and teachers in any scientific area. This package allows to efficiently store data fields in the time/space or in the frequency domain, to easily perform Fourier Transforms, to extract slices, to convert units, to compare several fields, etc. It therefore leads to simplified plot commands.

[CO] Improve error message when calling impossible plot #110

Open BonneelP opened 2 years ago

BonneelP commented 2 years ago

Hello all,

While working on a validation case for pyleecan I had the following issue: This PR https://github.com/Eomys/pyleecan/pull/529 introduces a new test "test_Bore_sym" in Tests/Validation/Magnetics/test_FEMM_periodicity.py where I compute the flux with/without angular sym. In both cases I set Nt_tot=1 and then I call (out of a copy/paste from another test with Nt_tot>1): 

    out.mag.B.plot_2D_Data(
        "time",
        "angle[0]{°}",
        data_list=[out2.mag.B],
        legend_list=["Periodic", "Full"],
        save_path=join(save_path, simu.name + "_B_time.png"),
        is_show_fig=False,
        **dict_2D
    )

and I get the following error: image

I guess the error is that I'm calling a plot on an axis with a size one. If I increase Nt_tot=4, there is no error. So I think it is just a matter of adding a check and a clearer error message (the requested plot doesn't make sense).

From the same copy paste, I also had: image I'm requesting time[1] which doesn't exist, so we could also provide a dedicated error message for this case.

Best regards, Pierre
