    Hello Rambo,

    The ObjectDataSource component can work with the object types listed in the Supported object types section. To use the class constructor, the class itself should implement a required interface or inherit one of the supported types. For example:
    public class Cars : List<Car>
    {
        public Cars()
        {
            Car car;
            car = new Car("Honda", "NSX GT", 2003 });
            this.Add(car);
     
            car = new Car("Nissan", "Skyline R34 GT-R", 2005 });
            this.Add(car);
        }
    }

    Otherwise, you will need to create a data retrieval method. For more information, please refer to the How to: Bind to a BusinessObject help article.

    Hello Rambo,

    The XAxis should be configured to use a DateTime scale. In this scenario, you will need to set the DateTimeScale properties such as BaseUnit and LabelUnit. If you do not set these properties, the graph might display too many axis labels and fill the whole graph with the raw chunk of data you are observing. For example, if you have data for a time span of a couple of years but the label unit and base unit are set to display every single hour on the axis, you will get so many axis labels that the graph won't be readable.
