You can get a handle (hl) to the "polyline" through several steps:

-->f = gcf();
Handle of type "Figure" with properties:
========================================
(here you can see all Figure properties with actual values)

-->a = f.children
 a  =
Handle of type "Axes" with properties:
======================================
(here you can see all Axes properties with actual values)

-->hl = a.children
 hl  =
Handle of type "Compound" with properties:
==========================================
parent: Axes
children: "Polyline"
visible = "on"
user_data = []

-->hl = hl.children
 hl  =
Handle of type "Polyline" with properties:
==========================================
(here you can see all Polyline properties with actual values)

Set the color to red:

-->hl.mark_foreground = 5;

Increase the point size:

-->hl.mark_size = 1;

If you change hl.mark_size_unit from "tabulated" to "points", you can get more sizes.
