Description yeray alonso 2014-03-19 08:10:12 EDT
Deppending on the Chart's width, the daMinMax DrawAllPointsStyle gives a strange result.
See the following example and resize the form to see how some "stairs" are drawn for the second series, while one would think it should be similar to the first series.
            this.Width = 820;
            tChart1.Aspect.View3D = false;
            tChart1.Legend.Visible = false;
            tChart1.Panel.MarginLeft = 7;
            tChart1.Panning.Allow = ScrollModes.Horizontal;
            tChart1.Dock = DockStyle.Fill;
            Axis cust1 = new Axis(tChart1.Chart);
            Axis cust2 = new Axis(tChart1.Chart);
            tChart1.Axes.Custom.Add(cust1);
            tChart1.Axes.Custom.Add(cust2);
            cust1.EndPosition = 48;
            cust2.StartPosition = 52;
            FastLine fast1 = new FastLine(tChart1.Chart);
            FastLine fast2 = new FastLine(tChart1.Chart);
            for (int i = 0; i < 1440; i++)
            {
                fast1.Add(100 * (i % 2));
                fast2.Add(100 * (i % 2));
            }
            fast1.CustomVertAxis = cust1;
            fast2.CustomVertAxis = cust2;
            fast2.DrawAllPoints = false;
            fast2.DrawAllPointsStyle = DrawAllPointsStyle.MinMax;

He is waiting for this to purchase the component. So he will want an evaluation dll to check this works as he wants...
