The fix for #2007 seems to create this issue
http://bugs.teechart.net/show_bug.cgi?id=2007

            tChart1.Legend.Visible = false;
            tChart1.Aspect.View3D = false;

            FastLine fast1 = new FastLine(tChart1.Chart);

            for (int i = 0; i < 20; i++)
                if (i == 10)
                    fast1.Add();
                else
                    fast1.Add(10);

            fast1.TreatNulls = TreatNullsStyle.DoNotPaint;

            tChart1.Axes.Left.SetMinMax(0, 15);
