Changing line color in a scatterplot without reconnecting points - A seemingly easy task..

Hi!

I'm posting because I have a scatterplot with 100 points, with each 5 points connected by a line, and with each group of 5 points disconnected from one another. Whenever I try to change the line color for the chart, it reconnects all of my groupings. Is there any way around this?

I attached an example file I just made. Basically, I want to change the color of the line attaching the points without reattaching the points where the line has been disconnected. I have to change the color of the line in some data I'm preparing for publication, with over 300 points in each graph, and they aren't always disconnected in equal intervals, so I'm trying to avoid having to change the line color, and then go back and re-separate them.

Thanks!
