Real-time chart & LoopPos

[User (Legacy)]

Hi,

I'm doing a real-time chart, and so far everything works great. I use a 

lines series, without markers. My problem, however, is that when the 

chart wraps around, point n (the last one I insert) is linked to point 

n+1 (which is now the oldest point in the chart). I've attached a 

screenshot with this message. Is there anyway I can prevent that?

Thanks,

Maan

This behavior is by design. The last point is always connected with the 

first point. In fact, the Line chart doesn't know that these points is the 

first and last, the data layer hides this and provides to the line chart the 

data in the order in which it appears in the screen.

You can however, control the color of this segment independently, which will 

allow you to make it transparent. Here is how:

chart1.Points.Clear();

chart1.Points[pointIndex].Color = Color.Blue;

Where pointIndex starts at 0 and keeps increasing with every point you add 

and goes back to zero when it reaches the bufferSize. In each iteration you 

would do something like:

pointIndex = (pointIndex + 1) % bufferSize
