I am trying to use tkinter and matplotlib to create an interface to pair with some lab equipment, but right now I am just loading in some old test data. I am trying to add in the NavigationToolbar2Tk navigation bar.
When I run the program the bar pops up properly but every time I click one of the buttons I get the error 'FigureCanvasTkAgg' object has no attribute 'manager'. The funny thing is that all of the buttons except for save will still perform their operations, they just continually spit out the errors. I have tried creating a seperate frame for the navigation box but that hasn't worked.
