Scatter slows down exponentially over time

Hello all,

I'm trying to run my code. Within a for loop, it plots x,y using scatter and continues to iterate. My problem is that when I try to see the code running in real-time using pause(1/1000000) (1 microsecond delay), the code starts slowing down exponentially upto the point that each scatter plots takes 1 second or more to appear on the graph. I timed my code and there is nothing slowing it down except scatter. Help is greatly appreciated.

performed a tic/toc of the scatter, results are attached.

Use scatter outside the loop

In other words, reduce the number of scatter objects -- they are expensive. You could aim for one per marker shape (okay, another layer for filled or not, and possibly one branch per marker edge color)

If I recall correctly from some old blog posts, after 100 points in a scatter object, scatter internally switches to patch representation.

Well I figured it out. Found this useful document. The axes limits were slowing the simultion down. May be this will be of help to others who encounter the same issue:
