Perhaps I should clarify seeing no responses yet. The key part I'm confused
about is if it is possible to reference graphs across classes. In my class
KinemWidget I have the following lines:
self.p1.setXLink(self.p2)
thermo=ThermoWidget()
self.p2.setXLink(thermo.p6)
The first line should be straightforward in that I am linking the x-axis of
the first graph to the second graph. However, I would also like to link the
x-axis of both of those graphs to a graph in another class (line 3). Is
this possible? If so is that the correct syntax to accomplish that?
If it is not possible to xlink across classes, is there another creative
way to xlink plots in two different tabs?
