Working with Nevron Chart for .NET - XYZ Scatter Graphs

nevron — Wed, 18 Jun 2008 10:04:00 GMT

Introduction

The requirements for presentation charts are always high and very often simple bars and lines are not enough to impress the audience. The rich feature set of Nevron Chart for .NET enables you to go beyond the limits of "ordinary" charts and opens a field of action for your imagination.

In this whitepaper you can track the process of creating a chart that presents data for the Carbon Dioxide emissions of European countries. We will try to get the most out of the component and set up a chart that is interesting, attractive and informative.

Data

First we have to examine the structure of the data and choose an appropriate form of representation.

The data source contains entries for 10 countries, where the following values are provided per country:

1. Actual CO2 emissions for the year 2005, measured in Million Metric Tons of CO2 Equivalent (MMTCO2). They are split into three categories by economy sectors that are major sources of energy-related CO2:

Electric Power Production
Transportation
Industrial, Commercial and Residential

2. Proposed emissions caps for the period 2008-2012 (MMTCO2 per year).

3. Granted emissions caps by the European commission for the same period (MMTCO2 per year).

Chart

The values in the first three columns add up to the total emissions for the year 2005, so they can be naturally represented as a stack. The fourth and the fifth values can be placed next to the stack, so that the proposed and granted emissions caps can be easily compared to the actual emissions. The cluster-stack combination that is formed can be displayed as a 2D plot:

An interesting idea is to make the chart 3-Dimensional and place the bars on top of the Europe map. For this purpose we'll create a Mesh surface series and texture it with a pre-rendered image of the Europe map. We'll also set the ratio of the X:Z chart dimensions to be equal to the X:Y ratio of the map image, so that the map is not distorted. For example if the image size is 540 x 650 pixels, we set the chart width to 54 and the chart depth to 65.

The XYZ cluster bar chart is a unique feature of Nevron Chart for .NET. It gives us the ability to place each cluster at arbitrary positions along the X and Z axes. We just have to fill the X and Z values in the first bar series of the cluster and set the UseXValues and UseZValues properties of the series to true.

The Y axis shouldn't be very long because otherwise the bars will get taller and will obstruct greater part of the image. With shorter bars the readability is decreased a little bit compared to the 2D chart, but in return we have a chart that looks really impressive.

Only a few finishing touches remain before the chart is complete. We'll place a title above the chart and a legend that explains the color coding of the bars. The built-in xml formatted texts will come helpful for splitting the long title into two lines and displaying the subscript in "CO2". A soft blurred shadow behind the title gives depth to the final image.

Nevron Chart for .NET has support for XYZ Scatter Stack/Cluster Bars, Line, Smooth Line, Point, Bubble, Shape and Error Bar Graphs.

Conclusion

Nevron Chart for .NET is in a class of its own when it comes to displaying true 3D charts like surface plots and XYZ scatters. The component offers a wide range of charting types with variety of applications and can be used for the creation of presentation charts with great visual impact. More information about the discussed features is available in the Users Guide shipped with the fully functional, not time restricted evaluation of the component available at http://www.nevron.com.

Nevron Diagram for .NET Q1 2008 - Released

nevron — Wed, 11 Jun 2008 14:16:00 GMT

Nevron Diagram has been designed from the ground up to meet a vast number of customization and extensibility requests. Built on top of the solid Model - View - Controller architecture it will provide your applications with consistent, intelligent and powerful diagramming abilities. Nevron Diagram for .NET is a unique component, since it integrates state-of-art vector and raster 2D graphics technologies and wraps them in an easy to use - yet completely customizable framework. As a result your applications can easily reuse it to instantly gain significant advantage in visual impact and intelligence. Following is a list of the new features introduced in this release:

Support for inward–outward port connections.
In this release we have implemented support for inward-outward ports. This feature lets you interactively glue an outward port to inward port. When an outward port of a shape is connected to an inward port, the shape will translate and rotate together with the shape owning the inward port. The translation aims to match the outward port location to the inward port location. The rotation aims to match both ports direction angles. For each type of port we have provided an extensive set of predefined modes in which a port can automatically determine its direction angle. Custom (user specified) direction angles are supported by all ports. This feature is extremely useful for interactive construction of connected shapes structures without edges. For example: in a floor plan diagram you can have a table with 4 inwards ports designated for the possible places where chairs can be placed. Chairs can have a single outward port. The placement of the chairs around the table is then a matter of simple drag and drop – Nevron Diagram will perform the snapping and glueing of the chairs to the table for you. When you move, rotate or resize the table the chairs will stay on their places.

Powerful support for graph, tree and cells layouts.
In this release we have added enterprise quality support for automatic layouts. The layouts are generally grouped in the following categories:

Graph Layouts – perform automatic arrangement of graph vertices and edges. Included the following layouts:
Force Directed Layouts - barycenter, spring and symmetrical. The implementation provides supports for lots of supplemental data provided on per edge and vertex basis. It addresses issues like magnetic fields, gravity force and vertex overlapping. The performance is significantly optimized due to the use of local temperatures. The overall quality of drawing is also improved because of the used global cooling method. It is suitable for any type of graph. Produces straight line graph drawings.
Layered Graph Layout – represents a classical implementation, which layouts a graph in layers. The layout addresses issues like crossing and bending minimization. It is suitable for any type of graph. Produces polyline graph drawings.
Orthogonal Graph Layout – represents a layout, which draws a graph only with horizontal or vertical line segments. The layout addresses issues like crossing minimization, bends minimization and overall compactness of the drawing. It is suitable for any type of graph. Produces orthogonal graph drawings.
Radial Graph Layout - represents a layout, which draws a graph in radial circles. It is suitable for any type of graph. Produces straight line graph drawings.
Tree Layouts – perform automatic arrangement of tree vertices and edges
Layered Tree Layout – layouts a tree in layers. The layout addresses the breadth compaction of the drawing. Produces straight line and orthogonal tree drawings.
Compact Depth Tree Layout – layouts a tree with minimal depth. The layout also addresses the breadth compaction of the drawing. Produces straight line and orthogonal tree drawings.
Tip Over Tree Layout - layouts a tree by placing children in either a row or a col. The row column children placement is controlled on a per vertex basis. Addresses the overall compaction of the drawing. Produces orthogonal tree drawings.
Balloon Tree Layout – layouts the tree in by placing the vertex children in a circular fashion. Addresses the overall compaction of the drawing. Produces straight line tree drawings.
Cell Layouts – perform automatic arrangement of the vertices of a graph
Stack Layout - represents a directed constrained cells layout, which stacks the cells in horizontal or vertical order. Depending on the layout direction the layout is constrained by either width or height.
Flow Layout - represents a directed constrained cells layout, which arranges the cells in horizontal or vertical lanes.
Dock Layout – represents space eating cells layout, which places vertices at per-vertex specified docking areas of the currently available layout area. Table Layout - represents a directed constrained cells layout, which arranges cells in a tabular manner.

Dynamic image map in AJAX mode
In Q1 2008 Nevron web components now support a dynamic image map that can be automatically updated at the client on every callback. The developer has control over when the image map is generated when is and updated on the client. The dynamic image map allows client side filtering of mouse events and prevents unnecessary callbacks for server side hit testing.

Controller-Tools Architecture in AJAX mode
Controller and tools are added to the Nevron client side JavaScript framework. All mouse events are now processed by the controller, which allows for implementing complex mouse handling logic and combining callback event processing with pure client side event processing.

New AJAX tools
Based on the controller-tools architecture, the following tools were added: - Click, double click, mouse down, mouse up, mouse move, mouse over and mouse out callback tools – intercept the mouse events and route them to the server for processing; - Dynamic cursor tool– changes the mouse cursor over interactive visual elements; - Redirect tool– redirects the browser to a specified URL when interactive visual elements are clicked; - Tooltip tool– displays tooltips over interactive visual elements.

Print Manager for Web Forms
None of the most popular web browsers is capable of printing really large images. Nevron .NET Vision Q1 2008 introduces a new HTTP handler that generates HTML, suitable for printing.

Future Improvements
The following list includes the improvements currently being developed in Nevron Diagram. Since they are beyond the scope of a single quarterly release, they will be embedded in the diagram when completely tested and implemented.

Pages
The diagram component will support pages. Each page will support different logical and display units, layers etc. The page will be controlled by a formula sheet.
Formula Shapes
Nevron diagram will support formula shapes. More details on this feature will be published additionally.

The suite introduces lots of modern custom controls such as MS Outlook 2003 NavigationPane, Windows XP ExplorerBar and complete set of extended Windows Forms controls making it easy to create a distinguished, stylish and modern end-user presentation layer.

What is new in version Q4 2007

NtreeList
The Q4 2007 release of Nevron User Interface for .NET introduces a powerful new control named NTreeList. This control combines the functionality of a tree-view and list-view and allows the display of tabular data with hierarchical relations . Supported are features like data-binding, multi-level grouping, sorting, clickable and resizable column and row headers, best fitting for both nodes and columns, column header drag-and-drop, etc. The control derives from the NTreeViewEx and inherits its speed, memory optimization and instant painting. Each row in the component is represented by an NTreeListNode which stores a collection of NTreeListNodeSubItem instances. Each sub-item may be attached to a desired column dynamically. Five predefined sub-items are provided:

NtreeListNodeStringSubItem – represents a node that displays simple text
NtreeListNodeImageSubItem – represents a node that displays a raster image
NtreeListNodeBooleanSubItem – represents a node that displays a Boolean value in the form of a check-box
NtreeListNodeNumericSubItem – represents a node that displays a formatted numeric value such as integer, float or double
NtreeListNodeDateTimeSubItem – represents a node that displays a formatted date-time value

Complete set of appearance formatting properties are provides allowing you to adjust the look-and-feel to your specific needs. Further more you may plug custom renderers and achieve virtually any specific visual requirement.

NfileExplorer
The NFileExplorer is a predefined NTreeList which may be used to browse the file system on the current machine. Each node is populated on demand, when expanded. The control retrieves the images used by the system for each drive, folder or file. An optional “Open file on activate” feature is provided enabling you to use shell execute of the selected file (open the file with the application associated with it).

Skinning – Individual Controls
The Nevron skinning support has been further improved and now you may assign a local skin to each INSkinnableControl instance. This gives you the freedom to combine different skins in one GUI layer.

ToolStrip Skin Renderer
An NToolStripSkinRenderer component is provided which allows you to make your .NET 2.0 tool-strips use the Nevron Skinning Logic. The renderer is applicable at either global or local level. It may be assigned different local skins or inherit the global skin from the NSkinManager.

Masked TextBox
The NMaskedTextBox control is an override of the standard .NET 2.0 MaskedTextBox and extends its appearance to match the Nevron one.

NTreeViewEx – added sorting, filtering and searching functionality
The NTreeViewEx has been extended with new useful functionality. The control can now be assigned a valid INFilter value which controls the visibility of the nodes. If a node becomes hidden by a filter it continues to exist in its parent collection but is no longer displayed. An NTreeNodeCollection can now be sorted, optionally recursively (all nested collections will also be sorted). A collection can be searched for specific nodes using filters logic. Provided are the predefined FindByText and FindByName methods.

Gallery panel – system images
The NSystemImages helper class can now retrieve an image from the system’s cache. The NGalleryPanel provides two special methods that can be used to load and display all the system images – either the small (16x16 pixels) or the large (32x32 pixels) ones.

Gallery Panel
The NGalleryPanel is an item-container control which mimics the Microsoft® Office 2007 galleries. 4 different types of item layout are provided so that the panel may be used as an extended list-box or list-view. Based on the Nevron generic UI element, the NGalleryItem component is highly customizable in each aspect of visual representation, including rich texts, alpha-blended images, custom item size, etc.

ListView
The NListView extends the standard Windows Forms ListView control and adds missing features like complete control over header and header items, alternating rows, column sorting, sorted column glyph, sorted column shading, custom scrollbars, etc.

Rotator
The NRotator is a very useful control which brings the popular "Rotator" feature from ASP.NET to your Windows Forms. The control contains a collection of frames where each frame is described by a generic UI element providing complete control over visual appearance, image and text. The well-designed set of properties will enable you with fine-tune control over frame duration, animation speed, animation direction plus much more.

Command Bars – ImageTextRelation
Provides complete control over the image and text entities of an NCommand object by specifying the ImageTextRelation property of its parent.

Task Dialog - Radio Buttons
The NTaskDialog is further extended and now it supports a set of radio-buttons for richer user experience. The radio buttons are layouted just below the Content section of the dialog.

Docking Panels - Sizing Restrictions
Nevron Docking Panels are now enabled with sizing restrictions in floating state. You may alter the MinimumSize, MaximumSize and Sizable properties of a floating container directly.

Docking Panels - Visual Tab Navigation
Nevron Docking Panels are the only Docking Library which enables you with the advanced CTRL+TAB visual navigation found in Microsoft® Visual Studio 2005. Pressing Ctrl+Tab will display a NPopup containing two gallery panels - one containing all active docking panels and one containing all active documents. Optionally this feature may be turned on and off via the VisualTabNavigation property of an NDockManager. You may also change the shortcut which triggers the pop-up.

Navigation Pane - Expand/Collapse
The NNavigationPane is extended with the Collapse/Expand feature found in Microsoft® Office 2007. By clicking the button on the caption of the pane you toggle its state. When the pane is collapsed you may display the currently active band by clicking in the area below the caption and above the buttons stack.
