Plotter class for nematic liquid crystals visualization, with the filters tree, in a Qt window.

Parameters:

  • filenames (list[str], str, or None, optional) – Files to import.

  • q0 (float, optional) – Chiral wavenumber for cholesteric (chiral nematic) ground state, used in free energy calculations.

  • user_settings (dict or None, optional) – Customizations to default plotter settings.

  • data_format (['open-Qmin' | 'Qmin' | 'director'], optional) – Formatting style of data text files to import; used only if parameter reader has value None.

  • sep (str, optional) – Column delimiter for imported text file(s)

  • reader (callable() or None, optional) – Function for reading data from text files; set to None to use the data_format (and, optionally, sep) parameters to determine data import behavior.

  • theme (['dark' | 'document' | 'paraview' | None], optional) – PyVista plot theme

  • dims (tuple(int) or None) – System size; used only if filenames is None.

  • data_stride (int, optional) – Data spacing; used only if filenames is None.

  • kwargs (dict, optional) – Keyword arguments to FilterTreePlot
