Running a long program while plotting slows down the program. How can I make it so that Matlab doesn't store so much data in the figure?

Hi, friends! I'm building a program that has to collect data and plot it for a long period of time (sometimes ranging past a week). However, the problem is it slows down when it runs for even more than a few hours. This causes problem with the data as it needs to be collected every second.
Converting data into single precision helped slightly, but the main problem is that Matlab is still storing lots of data somewhere, causing it to slow down. My best guess is the plot itself (which needs to display a 10 window), however, I cannot access it.
Is there a way to access the plot's data and compress it? Is there something else I should be looking at?
Thanks!
Edit: I have not profiled me code yet. I will do that and get back with what section is causing the slowdown.

If you cannot access the plot, then how could the data for the plot possibly be compressed?
Is it a line plot?
Which MATLAB version are you using?

This file exchange entry should help you plot even large data without significant slow-down.
