How to make scatter points into squares of a given size?

I would like to make a figure where my data points 'c' are squares of a given size instead of points.
The problem with the scatter function is that the points are too small. Making them larger will result in the data points overlaping.
x = (1:121);
y = zeros(1,121);
c = rand(1,121);
scatter(x,y,20,c)
Any help would be appreciated.
Many thanks,
Rob.

scatter(x, y, c, 'Marker', 's')
Note: Many readers would tend to associate the variable name 'c' with "color", but you are using it in a position associated with marker size.

Hi Walter,
Thanks for the reply. The 'c' variable is color. I want to represent the value of my data with color. I used rand in this case for the sake of the question.

scatter(x, y, [], c, 'Marker', 's')
The order is x, y, size, color, then property/value pairs.
