Problem with partial upd .. function, please help.

Hello.

I'm sorry to start another thread for OnPartialUpdate.

I know there is a lot on the forum, but I have not found a solution and an example that would solve my problem.

I will try to describe here what I need to call regularly via this function.

I have five slashes that I created in the font maker.

These slashes appear to me instead of seconds, ie 1 slash = first second.

It is like
"Knight Rider Car" reads slashes from left to right in seconds. 

The problem is that when I do dc.setClip at the bottom of the screen for slash size, width, height, I get to total time fast.

I would ask someone who could help me with this feature.

The best example of how to proceed.

Here's what I'm trying to do in OnPartialUpdate.

I do dcClearClip in OnUpdate...

Thank you

function onPartialUpdate(dc){
		sleepMode = true;

		
		
		dc.setClip(20, 175, 25, 20);
        dc.setColor(Graphics.COLOR_BLUE, Graphics.COLOR_TRANSPARENT);
        dc.drawText(20, 175, $.fontIcon_seconds, $.ICON_SECONDS, Gfx.TEXT_JUSTIFY_CENTER);
    	 
 
    	
        }
         }
