I've read many posts regarding this but I still can't find a solution to my problem.

I currently have a graph (stacked bar) in a report created with Visual Studio designer.

 

I then try to bind some data to the graph, but the graph always appears empty in the previews:

public GraphReport()
        {
            InitializeComponent();

            var h1 = new Person
            {
                Name = "John",
                Age = 28
            };

            var h2 = new Human
            {
                Name = "Carl",
                Age = 31
            };
            var list = new List<Human> { h1, h2 };
            graph1.DataSource = list;
        }

Hello Adrian,

I am not certain which preview is used. If you are referring to design-time preview it will not be available when the data for the Graph item is set in code-behind. To enable design-time preview you can configure ObjectDataSource component to retrieve the collection of Human objects and set it as Graph.DataSource property in the report designer.

In case, the Graph is empty when run-time preview is used my suggestion is to check if Category and Series groupings for the Graph item and the properties of the series are set correctly. Check this example as a reference.

In case the issue persists send us the problematic report in a support ticket so we can check the settings of the Graph item and provide you further suggestions.


Regards,
Katia
