How do I draw a thin line without it breaking up or becoming a dotted line?

I did see an old post on drawing a thin solid line - Any updates on this? The links are old and no longer available. When I draw a line using this method OR the newer drawing canvas, I cant seems to get a good "solid" line. It breaks up at times and becomes a dotted line if I dont draw slowly? Thoughts? Examples?

You need to draw with small segments, that start from the previous touch position and end at the current touch position.

Okay - I tested both of these and even though they work well, they still create "1985 MacPaint" bit-mapped looking lines. Are there any examples of one-pixel lines that are more natural? Like you might see in the app Noteability or Procreate? I realize Procreate is a heavy app, but I am just after a more natural LINE, not all of the fancy paint features. Thank you in advance.

You mean you need a smoother looking line? I think have seen examples here, but you'll have to google.

Yes - just something a bit more natural (smooth) with less bit mapped edges - especially when making a thin line. I will continue to look. But if you've used the mobile/tablet app Notability or Procreate - you'll know what I mean...

did you find a solution for it please?
