ASP.NET Core Line Charts Custom Visuals

You can implement custom visualizations for the Telerik UI for ASP.NET Core Line chart markers and highlights by utilizing the Kendo Drawing API. You can do that by setting a JavaScript function name as a string parameter of the Series:

• Markers -> Visual method: .Markers(markers => markers.Visual("markerVisual"))
• Highlight -> Toggle method -> .Highlight(highlight => highlight.Toggle("toggleHandler"));

Various context information is available through the function argument fields. Such are rect (the kendo.geometry.Rect that defines where the visual should be rendered), createVisual (a function that can be used to get the default visual) and options (different options depending on the item type).

You can read more about it in the ASP.NET Core JavaScript API reference.

This Line Charts example is part of unique collection of hundreds of ASP.NET Core demos, with which you can see all Telerik ASP.NET Core components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for ASP.NET Core or ThemeBuilder.
