Description
Today we display history data from only one case if multiple cases are selected in the QT plotter
/main/ert_gui/tools/plot/plot_window.py
case = plot_context.cases()[0] if plot_context.cases() else None
plot_context.history_data = self._api.history_data(key, case)
It might add value to the user to display the history data for all the cases selected (if the history data is different)

Research direction
Start in /main/ert_gui/tools/plot/plot_window.py at the history_data assignment and trace how plot_context.cases() and history_data are consumed by the QT plotter. Define how histories from multiple selected cases should appear, especially when they differ, and verify the plotter handles that result for all selected cases.
