This post shows how to add custom graphics to a chart by inheriting the SeriesRenderer class. We’ll use it to show marker lines on top of an area chart, which could be used to emphasize important values (e.g. dates on a timeline).
A frequent requirement for many kinds of diagrams is to keep their underlying graphs acyclic. If your application lets users draw diagrams interactively, you could prevent forming a cycle by rejecting new link between a pair of nodes that are already connected by a path.
Continue readingThis post demonstrates MindFusion.Diagramming API functionality that let you traverse connected diagram elements (following incident edges and adjacent nodes in graph-theory terminology). A diagram is treated as directed graph, where each node exposes incomingLinks and outgoingLinks collection properties, and respectively each link exposes origin and destination node properties. Thus the classic breadth-first search algorithm can be implemented like this for a diagram, with the callback parameter being invoked for each node, also reporting visit order and distance from initial node (as in length of shortest path in the graph):
In this blog post we look how you can create TableNode that render their cells following the logic of a list view: the tables have as many table columns and rows as needed in order to fit their content. The width of each column is fixed. When necessary, tables can be scrolled vertically. This is the final result:
In this post we’ll show how to implement Visio-like dynamic pagination of the diagram canvas, expanding or shrinking it while users draw nodes interactively, and rendering custom page borders. This is demonstrated using MindFusion Windows Forms Diagram control, but equivalent APIs are provided by MindFusion diagramming libraries for other platforms.
