I have fairly large plots, let's say an average of 3 dozens of plots, each with 10,000 points.
That's when I only load 1 file, and I can load 2 or 3 at the same time...
I only load the data that is visible (like the first ten second of data).
I only call replot() when necessary (when new data should be visible), and I unload data that should no longer be visible.
I don't use complex plot customization (line plot filing, big pen size...). I just color the plot from different file in diffenret color.
Also, there's nothing else running in background, whether on the computer or in the application itself.
The amount of data is just that big, and it is quite slow even when I only have one file loaded.
Is there some tricks to improve the performance? Or is it just an hardware limitation?
