Zheng model visualization spec

[plakrisenko]

The data seems to correspond to the Fig. S2, A, NTKO in the supplement. In the publication, aggregated values are visualized, e.g. sum of all observables where K27=0, i.e. K27me0K36me0 + K27me0K36me1 + K27me0K36me2 + K27me0K36me3

As suggested by @plakrisenko the same bounds can be used for the species by using:

   vis_spec_parser = VisSpecParser(
        petab_problem.condition_df, petab_problem.measurement_df, simulation_path
    )
    figure, dataprovider = vis_spec_parser.parse_from_vis_spec(visu_spec)
    figure.size = (40, 30)
    plotter = MPLPlotter(figure, dataprovider)
    axes = plotter.generate_figure(format_=extension)
    for ax in axes:
        axes[ax].set_ylim(bottom=0)
    plt.savefig(os.path.join(figures_dir, "Figure.png"))
