As the title suggests, same as the line plots but without the lines would be great for displaying scientific data.

I think if you change the following section in LinePlotAreaRenderer.cs from:

Code:
        matrix.TransformPoints(points);
        gfx.DrawLines(sri.LineFormat, points);
        DrawMarker(gfx, points, sri);


...to:

Code:
        matrix.TransformPoints(points);
        if sri.LineFormat.Width > 0:
            gfx.DrawLines(sri.LineFormat.Width, points);
        DrawMarker(gfx, points, sri);


...this would achieve the result - we'd just need to set the line width to 0.

This brings no success, because SeriesRendererInfo.LineFormat.Width internaly alway is set to ChartRenderer.DefaultSeriesLineWidth.
I think the better way is to set SeriesRendererInfo.LineFormat.Visible to false e.g. setting Series.LineFormat.Visible to false.
I tried this and it works!
