Problem of memory leak using FigureCanvasTkAgg

[GARCIA PIERRE SIMON p0904379]

Hello,

I'm PhD student in Bioinformatic and I'm working on a project using matplotlib and Tkinter but I've got a big problem of memory leak using these modules. I'll be very grateful if you could help me to solve this problem. Here is the link explaining what happends, with a reduced script:

Thank you in advance,

Sincerly,

It is likely there things are not being garbage collected due to either a missed reference surviving or the circular references between the various objects is delaying gc from collecting them (I do not recall the details exactly off the top of my head, but running gc manually with more generations may help).

However, if you are embedding in a GUI you are probably better off just doing the embedding directly (and skipping `pyplot` entirely, see https://matplotlib.org/examples/user_interfaces/embedding_in_tk.html ).  Re-using the Figures / Axes / Artists to update the data (rather than starting from scratch every time) may also prevent the memory leaks _and_ give you a performance boost.

The stackoverflow posting notes that mpl v1.1.1 was used, which is 5 years old. I am pretty sure we have made a lot of memory leak fixes since then. I noted as such on SO.
