Ok, let me rephrase my question then. HOW can I get the same (complex,
multi-plot) graph in two different windows with different zoom levels/sizes? My
attempts so far have only resulted in a second window showing the exact same
content as the first window - even when I resize the second window, it shows
the same content at the same size, simply cutting off the content at whatever
size the first window is.
If it helps, here is the incorrectly functioning code I used that gave me this
second window:
self.second_view = pg.PlotWidget()
self.second_view.setScene(self._ui.PlotWidget.scene())
self.second_view.show()
Where self._ui.PlotWidget is the initial instance of a pg.PlotWidget (I should
change the name, but whatever).
I suppose an alternate option is to simply make two completely separate graphs,
and graph the same thing in both, but I’m afraid this will kill performance and
memory usage, as my plots are quite large and complicated.
