 | - ThinWeb Chart Control
Nevron Chart contains a brand new AJAX web control called Nevron Chart ThinWeb. This control sets new standards in rich client side interactivity and requires no client side plugins, because it is completely HTML / JavaScript based. The core design goals of the control are:
- Simple Integration in Different Server environments - Nevron Chart ThinWeb can be easily integrated in any server side framework including ASP.NET WebForms and MVC.
- Cross Browser JavaScript - On the client side the control uses the JQuery library to improve cross browser compatibility. It works with all popular browsers including IE, Firefox, Chrome, Safari and Opera.
- Model - View - Controller architecture - The control implements the MVC pattern and provides an API which is consistent with the WinForm MVC implementation of the control. This makes the migration of WinForm applications really easy to the web world.
- Efficiency and Extensibility - The server and client side processing of the control are highly optimized, which results in a smoother web experience and less CPU load. At the same time you have great amount of flexibility to extend or customize the control.
- Some of the core features of Nevron Chart ThinWeb control are:
-
Ability to generate interactive image maps that can redirect the browser to a specified URL, display a customizable tooltip (CSS class, fade in / out delay etc.) or change the browser cursor.
-
Ability to intercept client side mouse events per chart element.
-
Ability to generate server side events.
-
Ability to generate postback events.
-
Support for Chart Zooming, Scrolling and Panning with many settings.
-
Support for interactive 3D rotation (Trackball).
-
Support for interactive gauge indicator dragging.
-
Support for custom requests and commands.
-
Integrated toolbar with lots of predefined actions.
- The new 2012.1 release also introduces the following features and improvements:
- Custom Series - A new series type is introduced that allows for painting of custom graphics in 2D Cartesian, Polar and Radar charts.
- Custom Painting in Overlay - Custom graphics can be painted in a separate layer over the chart control without the chart contents being repainted all the time. This feature can be useful for painting of interactive tools over densely populated charts.
- Triangulated Surface Simplification - The Triangulated Surface series features a data resampling algorithm that is able to significantly reduce the amount of rendered geometry and in the same time preserve the appearance of the surface close to the original.
- Data Import from .CSV files - The control supports direct import from CSV (Comma-Separated Values) files and streams.
- Data Import from Excel files - The control supports direct import from Excel files in XLS and XLSX file formats.
- Data Point Anchor for Pie Charts - A new type of anchor object allows for annotations and other panels to be attached to data points of a pie chart.
- Radar Axis Titles - The Radar Axis Titles are significantly improved and contain many new options for label positioning, layout and wrapping.
- Performance Improvements - The control features significantly improved performance. We've optimized the following features of the control:
- the Chart DOM model is now much more optimized when new objects or data are added or removed to the control. This reflects the configuration speed of all charting types.
- the Chart axes are optimized to perform much better when they have multiple labels and ticks. This reflects the rendering speed of Cartesian, polar and radar charting types.
- the Chart Image Map generation has been optimized - this reflects the legacy Chart WebForm control and Chart ThinWeb controls.
- specific series that require support for huge data sets are also additionally optimized - this includes all series that support sampling (Line, XY Scatter Line, Step Line, XY Step Line etc.) as well as all series that support clustering - Point, XY Scatter Point, XY Scatter Point, Triangulated Surface.
