Did you try the plot function:
plot(x, y, 'b.', 'MarkerSize', 20);
grid on;

Yes, every time I do this it erases the buttons at the bottom and the random point isnt plotted in the axes

I can't run an image. I need code. Attach your .mlapp file (if using App Designer) or .m and .fig file (if using GUIDE).

f= figure;
ax= axes('Parent',f,'Position',[0.05, 0.25, 0.9, 0.7]);
hold on;
my_button = uicontrol('style','pushbutton');
set(my_button, 'units', 'normalized', 'position', [0.05,0.05,0.3,0.15])
set(my_button, 'string','Add Point')
my_second_button = uicontrol('style','pushbutton');
set(my_second_button, 'units', 'normalized', 'position', [0.35,0.05,0.3,0.15])
set(my_second_button, 'string', 'Clear')
my_third_button = uicontrol('style', 'pushbutton');
set(my_third_button, 'units', 'normalized','position', [0.65,0.05,0.3,0.15])
set(my_third_button, 'string', 'Randomize')

No, why are you punishing yourself? That's so tedious. You didn't even specify any callback function. Just use AppDesigner like most everyone else.

What a cruel professor. Then you need to define a callback function, and then tell uicontrol() what the callback function's name is.
