xCenter = 0; yCenter = 0; thetaValue = 0:360; radiusJoint = 1;
jointZerox = radiusJoint*cosd(thetaValue)+xCenter; jointZeroy = radiusJoint*sind(thetaValue)+yCenter;
plot(jointZerox,jointZeroy,'b')

Use fill:
xCenter = 0;
yCenter = 0;
thetaValue = 0:360;
radiusJoint = 1;
jointZerox = radiusJoint*cosd(thetaValue)+xCenter;
jointZeroy = radiusJoint*sind(thetaValue)+yCenter;
fill(jointZerox,jointZeroy,'b')
axis equal

You can use my circles function. Just specify, x,y location, radius, and facecolor.

You might want to take a look at viscircles().
