Key Features
Comprehensive Chart Wizard
Building charts of any complexity is now much easier thanks to the new visual Chart Wizard. Using a Microsoft Excel-like interface the wizard provides control over 95% of the cart functionality. All modifications are previewed in real-time in the Visual Studio Design surface and can be completely rolled back if needed.
Secondary Y axis
RadChart supports secondary Y Axis, which provides the means to display series from different orders. Each chart series has now YAxisType property which sets the corresponding Y axis. The Y axis also supports logarithmic scaling.
See live demo.
Numerical X Axis
The X axis of RadChart can now be easily set as a numerical axis. As a result, you can set the series items on the right location depending on their XValue property. This is especially important when you receive data, which does not come on a regular basis and the chart has a time axis.
Drill-Down
This is a selection process, whereby a sub-set of data is displayed when the user clicks on a data point or corresponding legend item. In RadChart the drill-down functionality is implemented in two ways: using the postback event or by the client-side image maps.
Image Maps
Image maps allow you to define interactive areas within an image, which can be used for navigating to different pages (e.g. drill-down) and displaying tool tips.
Different Chart Types On a Single Chart
With Rad
Chart it is possible to specify a different chart type for each data series. For example, you can combine an Area and a Line chart, or a Bar and a Line chart,
as seen from the example on the left.
Automatic scaling of axes
Axes can automatically expand (or shrink) to accommodate dynamically added (or removed) axis marks, data points, etc.
Gradient fills, hatch fills, image fills
Building highly appealing charts is much easier now thanks to the new support for gradient fills, hatch fills, and image fills, which can be applied to all chart elements. This approach allows you to increase the chart readability, enhance the visual appeal, and achieve a 3D effect. The rich set of options gives you control over the gradient colors (gradient to transparency is also supported), direction, focus, hatch style, etc.
Negative values
RadChart is not limited to positive values or zero only. For all types of charts, excluding Pie charts, negative values are also allowed.
See a live demo.
Functionality
AJAX Zooming and Scrolling
Zooming and scrolling features allow users to explore portions of large charts in details with excellent performance. The user can zoom to a portion of the chart by dragging and selecting with the mouse (see left-most image below) to set a new scale for the chart. AJAX retrieves the visible "chunk" of the chart that was selected. The user can continue to navigate the chart by scrolling.
AutoLayout functionality
The AutoLayout functionality instructs the control to perform out-of-the-box layout arrangement that provides optimal utilization of the whole chart area and ensures that all chart elements are fully readable and do not overlap with one another.
Auto Text-wrapping
RadChart introduces automatic notepad-like word-wrapping functionality for the following text elements:
- Chart Title
- Chart Legend Item Labels
- Axis Item Labels
- Axis Labels
- MarkedZone Labels
- EmptySeriesMessage Label
- DataTable-related text elements
Automatic text-wrapping will be disabled by default but the chart control provides fine-grained API that allows you to enable wrapping for all elements, or alternatively on individual element basis.
Postback Events
With the postback events you can easily control the application behavior depending on a clicked chart item. The postback event handler allows you to get the clicked series, series item or legend item.
See live demo.
Advanced Axis Label Handling
RadChart now provides you with the ability to display time, date, currency, scientific, percent, etc. as axis label. You can also rotate the axis labels, change their color, font, min and max value, etc.
Custom Legends
Now you have the ability to control manually the behavior of the appearance of the legend. Additionally you can also define image map for the legend.
State Management
State management allows you to persist the data and/or properties on the client, instead of retrieving it from a database or remotely. This feature significantly accelerates the process of chart rendering.
Custom numeric formats for values
Allows for custom formatting of item values - i.e. currency, decimal digits, scientific notation, thousands separator, special formatting, etc.
Title and Legend positioning
Chart Title and Legend can be docked inside or outside the Chart Area, specifying alignment and distances from the margins.
Support for 10 image formats
You can choose to stream your charts in 10 different formats, including all popular web-formats - .jpg, .gif, and .png. This option enables you to optimize the quality and memory size of your chart images.
Different colors for series and for items in a serie
Allow you to achieve even better visual representation of data. Available for all chart types, including Bars, Area, and Lines - not only for the one-serie Pie chart, in which the Pieces are in different colors by default. The example below presents a Bar chart in which each item in the series has a different color.
Anti-aliasing control
Greater control over the text appearance is available in RadChart for ASP.NET AJAX thanks to the properties for anti-aliased text/legend and crisp web-style text.
"CandleStick" Chart Type
RadChart now supports CandleStick financial chart.
See live demo.
Support for Spline Curve Areas
The curve behaves the same way the normal spline curve does, but also offers the possibility to fill the belonging area.
See live demo.
“Strict mode” Support
RadChart now features a so-called "strict mode" for bar series. All XValues will be respected and bars will be positioned according to their XValues. If, however, you don't have any series items with XValues then RadChart will resume standard sequential ordering of each item.
See live demo.
Support for Empty Values Approximation
If your dataset is missing a value RadChart can approximate it for you.
See live demo.
Scalebreaks Support
Scalebreaks allow you to "break off" large chunks of the axis so that graphs with great amplitudes are easier to read.
See live demo.
Intelligent Labels
The new intelligent labels dramatically increasing readability in very busy charts. The charting engine now supports newline in all chart labels.
See live demo.
Support for Market Zones
The new Marked Zones now provide another option for chart customization.
See live demo.
Programming
Automatic data binding
RadChart supports now fully supports binding to data source for series and X axis.
See live demo.
Auto format styles and color palettes
The design time behavior of RadChart has been completely revamped to offer truly WYSIWYG experience. As a result, when you change chart styles and colors you can see the effect right away without compiling the application.
Unlimited number of series and data points in series
There is no limitation as to the number of series and data points in series displayed by Radchart. Feel free to add as many points and series as you need.
User-defined ranges for both axes
With Radchart it is possible to define the origin, end, and step for axes, range, or item per item, using the XML configuration file or programmatically.
