How to turn off UI slider handle properly?

Hi im making a health bar and i tried deleting the handle object containing the image, but now there is a gap of space between the filled mark and the end of the health bar. So how can i fill this up?

Try changing the Fill Rect Transform left/right (you can edit it visually by dragging it right).

I also wanted a value of 0 to be completely empty so modifying the Rect Tranform on the Fill Area and the Fill achieved this.
