rectangle to draw a line

Hi, I'm using rectangle to draw a circle then a line in a for loop. However, when I draw the second line, after drawing the circle, the line width is slimmer than the previous drawn line and even the next drawn lines.
I'm confuzed. I saved the handle and looked at the first created line and compared it to the second line. However, they are identical. Any advice?
Thank you
for m=1:10
rectangle('parent',handles.Axes9,'Position',[x,y,30,30],'Curvature',...
[1,1],'FaceColor',color);
rectangle('parent',handles.Axes9,'Position',...
x+14,y+30,1,h],'FaceColor','black');
text(x+8,y+15, {m},'fontsize',14,'color','black',...
'fontweight','bold','parent',handles.Axes9);
end

You probably need to use "hold on" in between those calls. But why not use line() or plot() to create a line? Why use rectangle to create a line?

This has been a useful example.
The code is correct and the display of the graphics is correct also. You see the effect, that rectangle draws to rounded pixel positions. And sometimes they are nearer to each other, such that the line looks smaller. When you resize the figure, you will see, that other lines are concerned.
