Thanks Alex, it looks better now. But the labels are actually at the beginning extremities, maybe it would be better to indeed have them at the end? Look at the example to see the current situation, it does not look so good when the lines are long (green and orange line), plus for me it is confusing to have the label at the beginning of the line (blue lines). 

Also, font size is not uniform anymore, I have no idea why this suddenly changed. Not pretty :-(
