How to avoid linking both ends of a Curve Plot

[teratux]

I'd try using two curves. First time through, add data to curve 1. When curve 1 reaches the end, start adding data to curve 2. At the same time, remove points from curve 1 to create the gap, then for each new point you add to curve 2, take one from the start of curve 1 to maintain the gap. When curve 1 has no more points, you have reached the end and now you start the process again by flipping curves.

thanks for the answer, that was my initial approach too, the application I'm developing uses 6 chart objects on screen and I felt having 12 charts at one point could be optimized. I started noticing some issues in performance when the application was running for 1 or 2 days non stop, but I could give it another go and see.
