    I have a graphic. In this graphic I need to show two moments. One moment, between a year range and other moment in other range. So, each range must be two diferent colors, in same line serie. I think to build two series, but when I put serie = 0, I heve a dot line, but I don't want a dot line, but invisible line. Is posible? Below my code:

    for (int i = 0; i < bl.doubleArray2009.Length; i++)
    if (bl.doubleArray2009[i] == 0)
    chartSeries2.Items[i].Empty = 
    true//Here a dot line and no invisible line 

    chartSeries2.Items[i].Visible = 
    for (int i = 0; i < bl.doubleArray2010.Length; i++)
       if (bl.doubleArray2010[i] == 0)
    chartSeries3.Items[i].Empty = 
    true;//Here a dot line and no invisible line
    chartSeries3.Items[i].Visible =

    You have complete control over the visual style of empty values. Hiding the dot line that appears can be achieved by setting the EmptyValue line color to transparent like this:
    chartSeries2.Appearance.EmptyValue.Line.Color = System.Drawing.Color.Transparent;
    Hope this helps.
