One more thing I forgot to mention is that you could use Swaping rows and columns, and if you have any negative points they will be drawn bellow zero crossing the actual X axis. Here is how to set it up:

ultraChart1.Data.SwapRowsAndColumns = true;

Hi

I tried your suggestion but I don't know If i explained myself correctly!

I need the yellow line to be a continous straight line through the x axis!

Is there any way to achieve this, stop the line changing its direction at month 1?

Thanks

If you also would like to have a line on zero coordinate, while moving X axis below zero, you can handle FillSceneGraph event and draw a line there, here is how:

private void ultraChart1_FillSceneGraph(object sender, Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs e)

        {

            IAdvanceAxis x = (IAdvanceAxis)e.Grid["X"];

            IAdvanceAxis y = (IAdvanceAxis)e.Grid["Y"];

            if (x != null)

            {

                int target = 0;

                int yVal = (int)y.Map(target);

                int xStart = (int)x.Map(0);

                int xEnd = (int)x.Map(5);

                Line line = new Line(new Point(xStart, yVal), new Point(xEnd, yVal));

                line.PE.Stroke = Color.Red;

                line.PE.StrokeWidth = 3;

                e.SceneGraph.Add(line);

            }

        }
