Sine Wave

[DiscoverIT]

Hello,

I am suffering from a mental block and require some help please.

I am trying to draw an accurate 4pt red sine wave.

I started with a red outline circle with a clear horizontal straight line through it and then slicing it.

I have enclosed an attachment and as you can see I am creating a red horizontal line that I cannot get rid of.

Any help would be appreciated.

Thank you, DiscoverIT
