How do I draw a smooth line(drawing canvas)?

Looking for some advice for drawing smooth lines with the canvas plugin I'm currently using this

But the lines have lots of gaps in them, the slower I move the mouse/touch, the more gaps there are in the lines.

I've tried adjusting the image points for the dots to center, left and right with the same result.

Any help would be appreciated, thanks.

Try changing "Cap" setting in Draw Line action.

dop2000 I've tried this, but the square cap settings leaves the lines looking like barbed wire lol.
