[Chennaipy] How to increase the speed of plotting in GUI(using Tkinter) using FigureCanvasTkAGG?

[aishwarya selvaraj]

Dear all,

I have 2 files created, one a .pyx file with a class named AndorCamersSDK
which has a function named LiveAcquisition(). The second file, a .py file
with a Class AndorCameraGUI which makes use of Tkinter to create a GUI.
This class has function LivePlot(), and RepeatPlot().Inside
LiveAcquisition() I am acquiring N number of frames and after acquiring
each frame I need to display it using LivePlot() and RepeatPlot(). Without
the display, just acquiring and storing for 300 frames takes 6.2 for
execution, which is fine by me. But When I start displaying it exceeds this
time limit. eg, it takes around 9 seconds for acquiring and displaying 300
images of size 512 x 512. I need to acquire and display within 6 sec for
300 frames.
How do I solve this?
