Moving a point in recoil atom distribution does not update the ratio in energy spectrum

[aleekaup2]

When point is moved in recoil atom distribution, the energy spectrum updates correctly but the values calculated by ratio tool will not update until the whole plot is redrawn.

Notes:

• Moving a point sends pyqtsignal which connects to the update_spectra() in matplotlib\energy_spectrum.py

• In the update_spectra() the .simu file gets recalculated by elem_sim.calculate_espe() and the new data is updated to the matplotlib.line2D object with self.plots[espe_file].set_data(data)

• However the ratio is not updated. Calling show_ratio() or on_span_select() again will not update the ratio but uses the old values.

• The on_span_select() seems to check the self.plots again: drawn_lines = { path: self.files_to_draw[path] for path, line in self.plots.items() if line.get_linestyle() != "None" }

• The drawn_lines is used for creating self.lines_of_area. In the show_ratio() the self.lines_of_area is then used in the __calculate_selected_area()

• All in all, for some reason self.plots[espe_file].set_data(data) does not seem to update self.plots.items()
