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 readingIn this blog post we will demonstrate how you can implement methods that save and load part of the information that a diagram renders into JSON format. The Diagram class has built-in toJson and fromJson methods. They serialize completely the diagram with every detail so you can restore it completely, exactly the way you see it. What we are going to do is write custom save and load methods that use only part of the information – namely the size and location of nodes and links as well as their text.
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 blog post we will build the financial chart that you see below. This is a candlestick chart created with MindFusion Charting for JavaScript. We use data from the platform TraderMade. The data comes in a continuous stream as a WebSocket. The blog post explains how to get the data, how to parse it and how to create and customize the chart. The chart also offers the user to change the data interval and to zoom in/out the chart.
