I have an image that looks like a read out of an EKG wavy line. It's in .EPS format and I have placed it in an Illustrator .AI file I am creating. I want to make the wavy line thicker looking but I cannot figure out how to do it. I tried increasing the stroke size from 1 to 2 but then at the start of every path a weird little short burr-like line gets added.
Can someone please let me know if there is a way I can make this line more wide/bold or whatever?
