Personally, I would use a simple 2D U8 array and keep it in a shift register without ever changing the size. Display it in an intensity graph resized for the correct number of pixels. For each new dot, you would just replace an existing element with a new value.

 

This way you could even  implement a fading. subtract 1 from the 2D array and replace the newest beam with 255. Now the older beam position are dimmer proportional to their age.


Here's what I had in mind.
