I am trying to add some stripes to my floating bar chart using custom code.

NAxisStripe s1 = chart.Axis(StandardAxis.PrimaryY).Stripes.Add(2, 3);

s1.FillStyle = new NColorFillStyle(Color.FromArgb(125, Color.SteelBlue));

s1.SetShowAtWall(ChartWallType.Back, true);

This doesnt show anything, though if i change the code to Primary X, it does show a horizontal line, I am not sure why I cant get a vertical line to show up.

My other question is, can I access my dataset from the embedded code?  I actually want to highlight sections of activities based on the person who performed the activity, but i am unsure how to go about this or even if this is possible?
