I am trying to plot (scatter) a series of data and based on the value of each data point, would like to color that marker with a specific color. Can this be done on Matlab? should I set the colormap? how in the m file?

well...
a hint:
- since you already mentioned it...

help scatter;

Thank you for the hint. I actually found out that gscatter would do what I need, which is to group different set of data and assign a color for them:

gscatter(vx,vy,mf4,'wbcr','s',80,0)

However, I need these markers (that are square shape) to be filled with the color that I have specified and everything (i.e. fill, set) I have tried hasn't worked. Anyone had done the same thing before.

Note that I can't use markerfacecolor property, as it will just set one color for all markers, or is there a workaround on that?

I am not familiar with gscatter()

scatter() produces a scattergroup object, which has a set of children,
each of which is a patch object with one vertex. You can adjust the
MarkerFaceColor property on the individual patches.
