If I have two series, is it possible to show the second series on top of the first?  Any help would be greatly appreciated.  Basically what I am trying to do is show an overlap in time as a red bar and the rest of the bar as a different color.

I figured it out.

myChart.Appearance.BarOverlapPercent = 100

Hello Jason,

The default behavior of the RadChart to horizontally split the available space can be worked around by giving different X values for each of the series. Here is a short example:
public partial class Form1 : Form 
    public Form1() 
    { 
        Random random = new Random(0x65412); 
 
        InitializeComponent(); 
 
        ChartSeries series = new ChartSeries(); 
        ChartSeries coverSeries = new ChartSeries(); 
        series.Type = ChartSeriesType.Gantt; 
        coverSeries.Type = ChartSeriesType.Gantt; 
        coverSeries.Appearance.LabelAppearance.Visible = false
 
        for (int i = 0; i < 10; i++) 
        { 
            ChartSeriesItem item = new ChartSeriesItem(); 
            item.YValue2 = random.Next(50, 100); 
            item.YValue = random.Next(150, 200); 
            item.XValue = i; 
            series.Items.Add(item); 
 
            ChartSeriesItem coverItem = new ChartSeriesItem(); 
            coverItem.YValue2 = random.Next(105, 120); 
            coverItem.YValue = random.Next(130, 145); 
            coverItem.XValue = i + 0.0001; 
            coverSeries.Items.Add(coverItem); 
        } 
 
        this.radChart1.Series.Add(series); 
        this.radChart1.Series.Add(coverSeries); 
    } 

As you can see, the index of the respective item is used as it's X value, but for the second series, a constant of 0.0001 is added. That will make the chart to draw the second series on top of the first one.

Best,
