Custom diagram canvas pagination

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.

Virtual Keyboard for Avalonia UI preview

We are soon releasing Avalonia version of our Virtual Keyboard control. It synthesizes keyboard events through Avalonia event routing system, so it should work on any platform supported by Avalonia UI. Unlike MindFusion Windows keyboard controls, events can be sent only to input controls in current process, and not to external processes.

In addition, language support cannot be generated automatically via OS APIs as in Windows controls, but we’ll be creating character maps for each language. Currently supported cultures that can be assigned to VirtualKeyboard.InputLocale property are en-US, fr-FR, de-DE and nl-NL.

If anyone is interested in trying the preview version, please install the nuget package –

Each chart type exposes numerous options to be customized in order to answer fully the requirements of the user. The control is packed with many samples that demonstrate different aspects of a chart type and offer ready-to-use code. The API is documented in details, with helpful tutorials and guides.

The chart component supports flexible data interface, which allows any data source to be used as a provider of chart data as long as it implements the Series interface. Predefined are a set of the most common data sources like XML, numeric lists, DateTime values, SQL database fields.

The innovative approach to styling lets developers control each aspect of the chart’s looks. They can alter the styling on the tiniest elements or concentrate on the bigger picture and create a global theme which can be reused.

Design custom shapes with WPF Diagram

Watch here the video for this tutorial.

This tutorial will run you through the process of creating custom WPF diagram shapes using the built-in Shape Designer. Keep in mind that the Designer is intended as a sample and is limited in terms of functionality. The designer is available inside the installation of MindFusion.Diagramming for WPF but is also included in this tutorial for convenience. For the purposes of this tutorial, we will create an ‘AND Gate’ circuit diagram shape as illustrated by the following image:

Circuit shapes

Run the Shape Designer application through the ShapeDesign.exe. The Shape Designer opens up with a single rectangular shape ready to be modified.

Diagramming WPF Circuit Shapes 1

The Shape Designer does not currently support shape renaming (remember, it’s just a sample), therefore create a new shape through the Shapes menu and name it ‘AndGate’.

Diagramming WPF Circuit Shapes 2

Select the newly created shape from the list on the left. In the editor select the right segment of the shape’s rectangle and press the DEL button on the keyboard. This will delete the segment and make the shape triangular.

Diagramming WPF Circuit Shapes 3

Adjust the end points of the shape segments so that it gets deflated on both sides. To adjust a segment, hover it with the mouse (so that its adjustment handles appear), then drag the handles.

Diagramming WPF Circuit Shapes 4

Select the arc primitive from the list on the right side of the screen. Drag this primitive over the top segment of the shape (until it gets highlighted in red) then drop.

Diagramming WPF Circuit Shapes 5

This will replace the line segment with an arc. Repeat the same process for the bottom segment of the shape.

Diagramming WPF Circuit Shapes 6

Adjust the middle point of both segments so that the shape looks protruded. Then drag three line primitives from the list on the right to the editor pane. Be careful not to drop the primitives over existing elements because this will replace the elements.

Diagramming WPF Circuit Shapes 7

Align the newly created line primitives with the existing shape.

Diagramming WPF Circuit Shapes 8

From the list with anchor points at the right side of the application, drag two anchor points from the first kind (input only) and one anchor point from the second kind (output only) and drop them inside the editor. Align the anchor points with the end points of the line segments created in the previous step.

Diagramming WPF Circuit Shapes 9

This will conclude the creation of the ‘AND Gate’ shape. You can test the shape in the preview diagram at the bottom of the screen.

Diagramming WPF Circuit Shapes 10

Save the shape library. Using the same approach, recreate the other circuit shapes from the image above. The following screenshot illustrates the complete library.

MindFusion Chart Control for WinForms, V4.0 Beta

MindFusion is proud to present you the beta version of Charting for WinForms, V4.0. MindFusion has entirely redesigned the control to create the most agile, lean and smart charting tool on the market. Below is a brief synopsis of the new chart for WinForms component.

New data model
Data that should be drawn in charts is read through an interface called Series, whose instances can be assigned to the Series properties of Chart and SeriesRenderer classes. You could implement this interface in your own model classes to avoid duplicating data. The library includes several pre-defined series classes that let you specify data via IList or array objects. For example, BarSeries lets you specify lists of values, inner labels and top labels, and PointSeries lets you specify data as a list of points.

New rendering model
Chart graphics are drawn inside Plot components by SeriesRenderer -derived objects. Each plot can contain multiple series renderers from same or different types. For example, you can draw area, line and bar graphics in same plot by adding AreaRenderer, LineRenderer and BarRenderer objects to its SeriesRenderers collection. Concrete Chart classes automatically generate a series renderer of appropriate type for their Series.

Dashboard
The Dashboard control can contain multiple plots, axes, legends, images, gauges and text blocks arranged in dynamic layout. Individual components can be added to dashboard’s default RootPanel or LayoutPanel containers, or for more complex layouts add intermediary panels such as GridPanel and StackPanel to the default ones.

The new WinForms Chart  has a built-in dashboard control.

Print and export
The Dashboard control and Chart controls that derive from it expose Print and PrintPreview methods for printing on paper. Call the ExportImage and CreateImage methods to generate bitmap image of the dashboard. The ExportPdf method exports the chart to a PDF (Portable Document Format) file. The ExportSvg method exports the chart to an SVG (Scalable Vector Graphics) file.

Styling
Values of appearance properties can come from several places in the component hierarchy. SeriesRenderer -derived objects can use attributes from their local SeriesStyle, from plot’s SeriesStyle, or from the *Series properties in current Theme. Component classes use either their local properties or ones defined in the theme. By default, appearance properties in SeriesRenderer and Component classes have null values, which makes the drawing code use values from the theme.

You can download the beta version directly from the link below. The archive file contains the control’s libraries, samples in C# and documentation.

About Chart for WinForms: This is a smart WinForms dashboard control that lets you add the perfect chart or gauge to your application in a few easy steps. The control provides an elegant data model, which supports equally well arrays, xml, any .NET data source, lists or any other data model class, that you create by implementing the Series interface.

MindFusion WinForms Chart boasts an innovative rendering model, where each chart graphics is drawn by its own SeriesRenderer on a Plot. Each Plot supports unlimited number of chart or gauge series of any type. Plots, together with axes, legends, gauges, images, and text blocks can be combined in a Dashboard with the built-in dashboard control. Styling the chart is done on various levels – from appearance properties in each SeriesRenderer to more general settings in the Component classes. The control supports themes and comes with a set of stylish themes, which you can customize as you wish or create new ones from scratch.

Persisting the chart is possible in several ways – printing, export to PDF or to Svg images – all of them performed with a single method call.

The newly designed chart control is offered with unchanged prices and license scheme – check it here.
