Mark lines can be very useful if you use display line charts and would like the legend to show descriptive information about them. In this case you may wish to synchronize the mark line with the line properties of the chart in order to visually associate the chart with the legend item. This is done automatically when the legend operates in Automatic mode.

The following examples adds a new item to the legend and changes the mark line properties.

Visual Basic

Dim legend As Legend = CType(NChartControl.Legends(0), Legend)
legend.Mode = LegendMode.Manual

Dim item As LegendDataItem =  New LegendDataItem() 
item.Text = "New item"
item.MarkShape = LegendMarkShape.None
item.LineProps.Width = 1
item.LineProps.Color = Color.Red

legend.Data.Array.Add(item)

C#

Legend legend = (Legend)NChartControl.Legends[0];
legend.Mode = LegendMode.Manual;

LegendDataItem item = new LegendDataItem();
item.Text = "New item";
item.MarkShape = LegendMarkShape.None;
item.LineProps.Width = 1;
item.LineProps.Color = Color.Red;

legend.Data.Array.Add(item);
