MindFusion Pack for WPF 2013.R2

Posted on by

MindFusion has just released Pack for WPF 2013.R2, which adds the following new features to the components in the pack:

chartMindFusion.Charting

Bubble Chart Control

You can now create beautiful bubble charts with the new BubbleChart class. The bubble chart can hold unlimited number of BubbleSeries. The appearance of the chart is completely customizable with various properties for the pens, brushes, labels and the other visual settings of the chart.

3D Charts Improvements

All 3D charts derive now from a new base class – the Chart3D class. This way the control has parallel 2D and 3D chart hierarchies. The 3D chart classes support most of the properties of the 2D classes.

Hit testing in 3D has been improved. The Chart3D.HitTest method returns a ChartHitTestResult3D object, which contains information about the result of the hit-testing operation and a list of ChartElement objects available in the 2D version.

The SurfaceChart exposes a variety of new properties including CloseModelFigure, Effect3D, SurfaceType. The SurfaceType property now enables the surface chart to display its associated data as scatter marks, rather than a surface. You can customize the scatter marks through the new properties in the SurfaceSeries class – ScatterSize, ScatterType, and ShowScatterFlag.

Chart Effects

You can now create visual effects in all 2D charts with the ChartEffect property.

Miscellaneous

Display 3D Graphs

You can use the new DiagramView3D control to display the elements of a diagram in 3D space. Assign the Diagram that should be displayed in this view to the Diagram property. DiagramView3D adds a 3D model to the scene for each node or link of the specified diagram. The positions of nodes in 3D coordinate space are specified via the Position3D attached property.

Import of OpenOffice Draw Files

Use the new DrawImporter class to import .odg files, which you have created with the OpenOffice Draw vector graphics editor. In order to use it, you must add a reference to the MindFusion.Diagramming.Wpf.DrawImport.dll assembly. Various overloads of the Import method can be used to import the OpenOffice drawing into a DiagramDocument whose pages correspond to the Draw pages, or into a single Diagram whose content is merged from all imported pages.

Import of Visio 2003 XML drawings

You can now import Visio 2003 XML Drawing files (*.vdx) into the Diagramming for Wpf wit the new VisioImporter. The standard Visio flowchart shapes, as well as most of the UML and Database entity shapes are imported to their closest representation in the MindFusion.Diagramming object model. The Visio connectors are imported as DiagramLink objects, preserving the relationship between the connected nodes. The Import method imports all Visio pages into a DiagramDocument, creating a DiagramPage for each page from the *.vdx file. The GetPageCount method gives you how many pages there are in a Visio document. Call the ImportPage method to import just a single page.

Miscellaneous

  • Improved appearance of hatch patterns used to draw frames for several HandlesStyle types.
  • Added support for loading HatchBrush objects from files saved by Windows Forms and ASP.NET versions of the diagramming control.
  • AttachTo overloads that attach nodes to link segments or control points now allow specifying negative index values.
  • Negative values are interpreted as relative to the last point or segment, regardless of the current number of link segments. For example, -2 denotes the second-to-last point or segment.
  • And much more.

MindFusion has released a new version of its pack for WinForms. Here is an overview of the new features:

chartMindFusion.Charting

Pie chart interactions

You can now resize every 2D or 3D pie chart by dragging the border between each two adjacent pieces with the mouse. The HitTestAngleOffset property lets you specify the deviation, in degrees, at which a click around the pieces border would still be considered a click on the border.

Support for undefined data values

You can add null (undefined) data values to all charts. The HandleEmptyValue property and the HandleEmptyValue enumeration specify the various ways null values can be handled.

ToolTips

You can now show tooltips for all chart types. In Area charts, tooltips can be displayed for every section between each two adjacent points.

Themes

Chart themes are now represented as XML files and we provide you with an initial set of 8. You can use the SaveTheme and LoadTheme methods to save/load a theme. There is also a theme editor control that lets you create, save and preview themes fast and easy.

Major/minor axis ticks

You can divide all chart axes more precisely using the new MajorTickLength and MinorTickLength properties. When their value is greater than zero, ticks are drawn not only at the axis intervals but also among them. You can customize the number of minor ticks with the MinorTicksPerInterval property.

Miscellaneous

  • Hit testing has been imrpoved in 3D cylinders and area charts
  • custom number formatting has been added to all numeric labels
  • several API changes were introduced

diagram16x16MindFusion.Diagramming

Support for Mono

You can use MindFusion.Diagramming component under the Mono runtime for OSX or Linux. A single version of the mindfusion.* assemblies can be referenced by both Mono and Microsoft .NET applications. The control detects what runtime has loaded it, and provides alternative implementations for features that are currently missing from Mono.

Custom measure units

The type of the MeasureUnit property has been changed from GraphicsUnit enum to MeasureUnit class. This class lets you define custom units by specifying their dots-per inch resolution, a string name, and number of standard divisions for display in the Ruler control. There are two new predefined units available out of the box: Centimeter and WpfPoint.

Shape control points

You can parameterize Shape formulas by associating control points with Shape objects. Each control point is passed to the shape script as a named variable. You can also specify the default, min and max coordinates for each parameter via the ShapeControlPoint constructor, and whether to treat its values as percents or fixed offset.

ContainerNode improvements

  • Child nodes are now drawn by their containers; when containers overlap, the children of a lower container cannot appear in front of the upper container anymore;
  • The ClipChildren property specifies whether to clip child items to container’s boundaries;
  • The ZIndex property no longer changes automatically when dropping nodes into a container;

In order to use it, you must add a reference to the MindFusion.Diagramming.Import.Draw.dll assembly. Various overloads of the Import method can be used to import the OpenOffice drawing into a DiagramDocument whose pages correspond to the Draw pages, or into a single Diagram whose content is merged from all imported pages.

PdfExporter improvements

  • Improved handling of clip regions in custom drawing code;
  • PdfExporter now honors the target Rectangle property of linear gradients;
  • PDF shadings now include all colors from a ColorBlend;

New events

  • The SetSelfLoopShape event is raised when a link becomes a self-loop, giving you a chance to set a custom shape for the link;
  • QueryAlignTarget event is raised to determine if a node should be used as alignment guide target when AutoAlignNodes is enabled;

Report-16x16 MindFusion.Reporting

Several bug fixes and improvements.

ASP.NET Bar Chart with Custom Labels

Posted on by

In this blog post we will look on how to build a bar chart with multiple series, custom X-labels and inner labels using MindFusion.Charting for ASP.NET control.

1. General Appearance of the Chart

We want to show three data series and we want to show the first values of each series in a cluster, then second cluster with the second values of each series etc. In order to render the bars in this order we set the BarType property to BarType.Clustered3D. We correct the Depth3D to make the bars less thick and increase the distance between each series with DistBtwBars. We make the bars wider, setting BarWidth to 30.

    //general appearance
    BarChart1.BarType = MindFusion.Charting.BarType.Clustered3D;
    BarChart1.BarWidth = 30f;        
    BarChart1.Depth3D = 15f;
    BarChart1.DistBtwBars = 10f;

2. Grid

Our bars are vertical e.g. it is a column chart, so we would like to have a horizontal grid. We set the GridType property to GridType.HorScale and we set the AltGridBrush and GridBruh to different gray colors to give us nice alternating grid stripes. For the outlining of the whole plot area we use the PlotAreaOutlinePen.

    //grid settings
    BarChart1.GridBrush= new MindFusion.Drawing.SolidBrush(System.Drawing.Color.FromArgb(242, 239, 224));
    BarChart1.GridPen= new MindFusion.Drawing.Pen(System.Drawing.Color.FromArgb(204, 196, 185));
    BarChart1.GridType = MindFusion.Charting.GridType.HorScale;
    BarChart1.PlotAreaOutlinePen = new MindFusion.Drawing.Pen(System.Drawing.Color.FromArgb(204, 196, 185));

3. Labels Inside Bars

The labels inside bars show the data of each bar – this is done by setting the InnerLabelType property to LabelType.Data. We use a white LabelBrush to draw the labels and set their InnerLabelBorder to Border.RoundedRect. The background of the inner labels is set to gray.

    //inner labels settings
    BarChart1.InnerLabelBackground = new MindFusion.Drawing.SolidBrush(System.Drawing.Color.FromArgb(112, 128, 144));
    BarChart1.InnerLabelBorder = MindFusion.Charting.Border.RoundedRect;
    BarChart1.InnerLabelType = MindFusion.Charting.LabelType.Data; 
    BarChart1.LabelBrush = new MindFusion.Drawing.SolidBrush(System.Drawing.Color.FromArgb(255, 255, 255));

4. Title

We want not only title but also second title – or a subtitle. That’s why we use both the TitleText and SubTitleText properties. We leave no distance between them – we set SubTitleOffset to 0. But we would like the two titles to be well above the plot area, that’s why we set bigger TitleOffset.

    //title and subtitle
    BarChart1.SubTitleOffset = 30;
    BarChart1.SubTitleText = "all major continents";
    BarChart1.TitleOffset = 0;
    BarChart1.TitleText = "Sales";

5. Labels at the Axes

The X-labels are custom text – we set them with XLabels. The title of the Y-axis is rotated, so we use LabelOrientation.BottomToTop.

    //axes labels settings
    BarChart1.XAxisSettings.LabelSeriesIndex = 1;
    BarChart1.XLabels.Clear();
    BarChart1.XLabels.Add(new List(){ "Europe", "Asia", "North America", "South America"});
    
    BarChart1.YAxisSettings.TitleLabel = "in mlns. USD";
    BarChart1.YAxisSettings.TitleLabelOrientation = MindFusion.Charting.LabelOrientation.BottomToTop;
