speed error

[matin7777]

We wrote a program for our staff that we had two major bugs.
The program will generate a signal, and start plotting several figures. But after some time, the program gets slower and slower response to the user input.  it will not respond immediately. This is the first bug.
The second bug is the constant increase in the time of data processing . At one point the buffer overload and the software either hangs or stops drawing the maps. Obviously, it should not do that, and the whole image should be displayed.

We cannot help unless you show us some code.

(Obviously, you are growing data structures without bounds. What are you he "maps" you are drawing? 2d pictures? Xy graphs?)

Can you attach your code? There's really not much we can say without seeing what you are doing.
