ABOUT THIS DEMO:

You may use your own code to bind complex data to the chart. Simply build your hierarchy of Entities, and set the chart's RootEntity property. In this demo, this approach is used, and a different color is applied to each level in the hierarchy. View the code to see how this is accomplished.

    private IDrawnEntity ToEntity(DataTable dt, DataRow dr, IDrawnEntity parent, int level)
    {
        DefaultDrawnEntity newEntity = new DefaultDrawnEntity((string)dr["FullName"], orgDemo);
        newEntity.Identity = ((int)dr["PersonID"]).ToString();

        if (parent != null) parent.AddChild(newEntity);

        DataRow[] children = dt.Select("ParentPersonID = " + dr["PersonID"].ToString());
        foreach (DataRow child in children)
        {
            ToEntity(dt, child, newEntity, level + 1);
        }

        newEntity.FillBrush = new LinearGradientBrush(
            new Rectangle(0, 0, newEntity.BoxSize.Width, newEntity.BoxSize.Height),
            Color.White,
            Color.FromArgb(200, colors[level]),
            LinearGradientMode.Vertical);

        return newEntity;
    }
