    Gauge Overview
    In This Topic

    Nevron Gauge for SharePoint is an advanced web part, which delivers a complete set of radial and linear gauges, numeric displays and state indicators which are driven by pivot data aggregation. This allows the creation of complex gauges, that are tightly integrated with your data to be done visually and directly in SharePoint environment.

     Major Features

    Support for Multiple Gauge Areas - unlimited number of gauge areas are supported. Each gauge area has its own gauge type. Gauge areas can be automatically or manually arranged. Gauge areas can be nested into one another to create sub gauges.

    Support for Multiple Titles - unlimited number of titles are supported. Titles can be manually positioned or docked to gauge, gauge areas and gauge plot areas.

    Gauge Types - a gauge type is assigned to each gauge area. Supported are the following gauge types:

    • Radial - displays axes, ranges and pointers in a circular fashion.
      Sub Types: Radial, Quarter North East, Quarter North West, Quarter South West, Quarter South East, Half North, Half South, Half West, Half East and Custom. When using Custom subtype the user can specify custom begin angle, sweep angle, border style etc.
    • Linear - displays axes, ranges and pointers in a linear fashion.
      Sub Types: Horizontal and Vertical.
    • Numeric Display - displays a value in a fashion similar to a LED display.
      Display Styles: Seven Segment Normal, Seven Segment Rounded, Seven Segment Rectangular, Fourteen Segment Normal, Fourteen Segment Rectangular, Fourteen SegmentInset, Matrix Rectangle and Matrix Circle.
    • State Indicator - supplementary gauges, typically used to visually prompt the user that a value has entered a critical range.

    Axes - radial and linear gauges support an unlimited number of axes, packed with a complete set of features designed to solve even the most complex gauge requirements.

    Ranges - radial and linear gauges support an unlimited number of ranges. Ranges help you visualize the coverage of a values range on a certain axis.

    Pointers - radial and linear gauge types support an unlimited number of pointers. Pointers help you visualize a value on a certain axis. Radial gauges support numerous needle styles. Both linear and radial gauges can display pointers as markers.

    Gauge Formulas - gauges are designed to provide data analysis to sets of numeric values. Gauge formulas can be applied to the aggregated sets applicable to axis ranges {min and max}, ranges {begin and end} and pointer and numeric display values. Supported are the following gauge formulas:

    • Min - finds the min value from a set.
    • Max - finds the max value from a set.
    • Average - finds the average value from a set.
    • Median - finds the value that splits the set in half (e.g. half of the values are smaller than median value and half are larger).
    • First - gets the first value from a set.
    • Last - gets the last value from a set.
    • Sum - gets the sum of all values in the set
    • Count - gets the count of the values in the set
    • Percentile - finds the value that splits the set in a custom percent.
    • Variance - the variance is used to measure the tendency of the values in the set to deviate from the average.
    • Standard Deviation - Returns the standard deviation of the values in the set.


    • Support for different image formats
    • Image sizing options
    • On/off image map rendering
    • Control over text and geometry antialiasing
    • Control over the currently used culture settings. You can select a custom culture or synchronize the currently used culture with the user regional settings.

    Appearance Customizations

    • Fill Style editor - helps you define the filling of an element. Provides options for solid color, gradient and hatch fill types.
    • Stroke Style editor - helps you define the outline/stroke of an element. Provides options for line caps and joins, line pattern and color. 
    • Shadow Style editor - helps you define the shadow which is cast by an element. Provides options for solid, linear, radial blur and gaussian blur shadows.
    • Text Style editor - helps you define the default appearance of a text element. Provides options for font size and type, font filling, outline, shadow, backplane etc. 
    • Frame Style editor - helps you define the frame of the component and its panels. Supports artistic/image borders. 

    Code Embedding - allows you to modify every aspect of the gauge using C# or VB.NET code.

    Templates - allows you to save and load the component state inside the web part designer.

     Unique Features

    Advanced Pivot Aggregation - the pivot data aggregation capabilities embedded in the product are only comparable to the ones provided by leading reporting tools. However none of these solutions provides this level of flexibility and ease of configuration inside SharePoint nor the advanced data visualization of Nevron.

    Expressions Everywhere - nearly all aspects of the web part (from the data source connection, through the data aggregation and data visualization) can be controlled by expressions, which means that you can bind nearly everything to user defined preferences and data.

    Image Filters - the only gauge for SharePoint to provide Adobe Photoshop like image filter effects, which are applicable to all gauge elements - these include bevel, emboss, lighting filters etc. When it comes to shadows it is the only gauge for SharePoint, which has soft shadows (based on Gaussian and Radial blur image filters).

    XML Formatted Texts - this feature is applicable to all elements which display text. It allows you to mix fonts, mix bold, italic underline formatting and many other advanced features like different fill styles, shadows, image filters etc. - all inside a single label, title etc. XML formatted texts use a format similar to HTML, but with many more advanced options.

    Blazing Fast Gauge Designer - Nevron Gauge for SharePoint features an advanced designer, which is built with jQuery UI. The designer supports all major web browsers and does not require any plugins (like Silverlight or Flash). It does not use postbacks, MS ASP.NET controls or MS AJAX, which ensures that the client-server communication is brought to a minimum. The server-side UI processing is pure HTML and script rendering. The client-side is pure HTML, CSS and jQuery JavaScript.
